How to Clean Holmes Air Purifier – A Step-By-Step Guide


You must be wondering how to clean Holmes air purifier if you’re a proud owner of this brand.

Regular cleaning and maintenance are crucial to ensure optimal performance.

Think of it like giving your car a routine check-up. You want to make sure it’s running smoothly and efficiently. 

Not to mention, it can also save you money over time by avoiding expensive repairs. 

Today, we will dive into the world of Holmes air purifiers and give you all the tips and tricks you need to keep your unit in tip-top shape. 

Let’s get started, shall we?

How to Clean Holmes Air Purifier – Cleaning the Exterior Unit

Before diving into the nitty-gritty of cleaning your Holmes air purifier, you must prepare. 

First things first, unplug your unit! You don’t want any accidental turn-ons or shocks.

Next, remove the filter. This will let you clean it properly and separately from the rest of the unit. 

Now, gather all the necessary cleaning supplies:

  • damp cloth or sponge
  • toothbrush
  • brush
  • vacuum
  • mild detergent 

If you’re all set, let’s get cleaning!

STEP #1: Wipe to Clean

Begin by wiping the unit’s exterior with a damp cloth or sponge, paying special attention to buttons, handles, and other areas where dirt and grime may have accumulated.

If you need to use a mild detergent to remove any stubborn stains or grime, rinse the unit thoroughly with water to remove any residue.

STEP #2: Wipe to Dry

Dry off the unit with a clean cloth or towel, making sure to buff it to a shiny finish

Add some personality. Give it a name, or make it fun by adding some music.

Take a step back and admire your handiwork. You’re off to a great start!

Now let’s talk about how to clean Holmes air purifier filters.

How to Clean Holmes Air Purifier – Cleaning the Filters

Depending on your model, your air purifier may run a True HEPA filter or a HEPA-Type filter. 

If it uses a True HEPA filter, it can trap almost all particles 0.3 microns or larger.

On the other hand, HEPA-type can capture particles up to 2 microns in size, with an efficiency of 99%.

Clean Holmes Air Purifier HEPA filters

Okay, so you’re ready to give your Holmes purifier a little TLC and give that HEPA filter a good cleaning. 

No worries, it’s a simple process. 

STEP#1: Remove the HEPA filter

Most Holmes models have a removable panel on the front of the unit. 

This panel is where dirty air comes in, and clean air comes out. All you have to do is take out the grille to retrieve the HEPA filter.

STEP #2: Fill a sink with warm water

It’s time to give your Holmes air purifier’s HEPA/HEPA-type filter a good cleanse. 

First, head over to the sink and turn on the warm water. 

Next, add soap to the water. 

Take the filter and give it a nice soak for 10-15 minutes. 

The warm soapy water will help loosen up any built-up dirt or grime.

But watch out. Before submerging the filter, turn off the water to prevent it from hitting it directly with too much force. 

Give the filter a few gentle movements in and out of the water to let the water flow through it.

STEP #3: Rinse with warm water

Time to give your filter a rinse! 

First, take it out of the soapy water. 

Next, turn on the warm water and let it run in the sink. 

Now, put the filter back in the water and give it a few gentle movements in and out of the water, allowing the water to flow through it. 

You may need to do this step twice to ensure it’s extra clean. 

And that’s it! Your filter is now clean and ready to go.

STEP #4: Sterilize (Optional)

If you want to give your filter an extra TLC, sterilize it before drying. 

Grab a half sinkful of warm water and add bleach.

Dip the filter in and give it a gentle swish. 

However, some manufacturers don’t recommend it, as bleach can damage the filter. 

Instead, use a natural sterilizing option like hydrogen peroxide or white vinegar. 

Simply mix a small amount with warm water and dip the filter in the solution for a few minutes. 

But keep in mind that this step is optional. You can skip it if you want.

STEP #5: Dry the clean filter

Now that your Holmes HEPA-Type filter is clean and sparkly, it’s time to dry it off! 

Find a dry, fluffy towel and lay your filter on top. Let it sit for about 30 minutes. 

Or, if you’re feeling lazy, you can pop it back in the purifier and let the unit’s air circulation do the work for you. 

Either way, your filter will be good as new and ready to tackle those pollutants!

Clean Holmes Air Purifier Pre-filters

Cleaning your Holmes air purifier’s pre-filters is a breeze! 

These washable foam filters are a lifesaver, trapping pet hair, dust, and other big debris before they reach the main filter. 

The manufacturer suggests giving these filters a good clean once a month. 

But first, you must check the pre-filter every three weeks to see if it needs cleaning.

If it looks worse for wear, it’s probably time to swap it out for a new one. 

But if it’s just a bit dusty, give it a quick shake to freshen it up. 

And if it’s covered in pet fur, lint, and other debris, it’s time for a good cleaning session.

Now, how can you clean it? Follow these steps to learn how to clean Holmes air purifier filters.

STEP #1: Remove the Pre-filter

Start by opening the unit’s front cover and removing the pre-filter. Pretty straightforward.

STEP #2: Wash the Pre-filter

Gently wash the pre-filter in a sink or bucket of warm water with a bit of mild soap.

Give the soiled pre-filter a good scrub with your hands. You can also use a soft-bristled brush or cloth.

STEP #3: Rinse and Dry

Rinse off all the soap with warm water and place the pre-filter on a terry cloth towel to dry.

Dry off the pre-filter by placing it on a towel or leaving it in the sun for 15 minutes if the weather is nice. If not, use a fan to speed up the drying process.

Once it’s dry, pop the pre-filter back into the unit. Voila! A fresh, clean pre-filter for your Holmes air purifier.

Clean Holmes Air Purifier Carbon Filters

Activated carbon filters, also called charcoal filters, are a powerful addition to any air purification system. 

Think of them as a secret weapon, if you will. 

They help capture particles that HEPA can’t handle efficiently. 

This includes exhaust fumes, VOCs, and wildfire smoke. 

But like any secret weapon, they need maintenance to keep working properly.

Holmes suggests changing the filters every three months and warns against washing. 

The good news is; you don’t have to wash these filters. Instead, you use a vacuum to light-clean. 

Not only is it easy, but it’ll also help extend the life of your filter.

Follow these steps to keep your Holmes carbon filter in top condition.

STEP #1: Unplug your Device

First things first, switch off your unit and unplug the air purifier.

STEP #2: Use your Vacuum

Now it’s time for a bit of cleaning. Use a vacuum and attach a crevice tool.

Work gently in long, smooth strokes. You can do two passes over the filter to clean it effectively.

or STEP #3: Replace the Filter

If it still looks dirty, replace the carbon filter, and that’s it!

Which Filter Types Are Cleanable and Reusable?

Not all air filters are cut from the same cloth. 

You can give some filters a good clean and reuse them while others need replacement. 

For example, if you live in an area with lots of VOCs, replace True HEPA filters every six months or yearly. 

But don’t despair! Electrostatic and activated carbon filters are generally good to go after a good cleaning. 

You can also clean and reuse some HEPA-style filters.

On the other hand, air ionizers and ozone air purifiers don’t require filters. 

So you don’t have to worry about cleaning or replacing them. 

But if your air filter is labeled permanent or washable, feel free to clean and wash it for continued use. 

And you’re in luck! This article has outlined helpful instructions describing how to clean Holmes air purifier filters.

Why Is Cleaning Air Purifier Filters Important?

Cleaning your air purifier filter is a no-brainer. 

Well, it’s not just a money saver but also keeps your air purifier running at peak performance. 

Let’s face it, air filters get dirty and clogged over time, and if you don’t clean them, your air purifier is just a fancy fan. 

So, instead of constantly buying new filters, why not clean your current one well? It’s just the logical thing to do.

Maintaining Your Holmes Air Purifier

Now that you know how to clean Holmes air purifier and filter, let’s talk maintenance.

Keeping your Holmes air purifier running at its best is easy. 

One easy tip is to check the filters every few weeks. 

Remember, the lifespan of your filters can vary, depending on the air quality and how often you use it. 

Generally, true HEPA filters last for about 12 to 18 months under normal conditions. But you must replace carbon filters every 60 to 90 days.

For those who don’t know when to replace filters, your Holmes air purifier will give you a clear sign. 

Typically, the filter reset button will turn red, telling you it’s time to get new filters. 

And replacing them is as simple as 1, 2, 3! Here’s how:

  • Switch off the air purifier and unplug it from the wall outlet.
  • Press the Door Release Button and open the front air inlet grill door to get to the filter compartment.
  • Gently pull out the filters from the unit.
  • Inspect the filters; if they appear dirty or clogged, it’s time to replace them.
  • Replacing the carbon filters is simple. Just take out the old ones and put in the new ones. Remove the plastic bag first and use the plastic tab as a guide.
  • To replace the HEPA filters, pull the old one and put the new one in its place.
  • Once you’ve replaced the filters, close the front air inlet grill door and connect the air purifier back to the wall outlet.
  • Press and hold the Filter Reset Button for three seconds to reset it. If a green indicator light appears, you’ve successfully reset the Filter Life Monitor. Easy peasy!

How to Clean Holmes Air Purifier? – FAQs

Does an Air Purifier Help with Dog Smell?


Are you a dog owner who wonders if an air purifier help with dog smell?

You’re probably like me, who loves your dog but is not so thrilled with that less-than-pleasant odor. Trust me, I feel you!

Lucky for us, the following will be more information that we could/would ever want to know about air purifiers and odors—from a pet and otherwise.

I’ll be nice and give you the TLDR version up front. Yes. An air purifier can help with dog smell and a variety of other smells too. 

But not all air purifiers or filters are capable of removing odors, mind you!

While a HEPA filter is your go-to for catching airborne particulates, you need a purifier with a carbon filter to trap and neutralize odors.


Why Does Your Dog Smell?

Don’t worry – it’s not because you’re a terrible pet owner.

For the most part, your dog — or any other furry pet — smells because of the production of bacteria and yeast. This is entirely natural, so don’t freak out.

This bacteria and yeast form on dark or damp spots on your dog’s body — like inside their ears — and the odor is typically worse when your dog is wet. 

However, suppose you find the smell overwhelming. In that case, your dog could have a health-related problem that should be diagnosed and treated.

And there are a few other reasons behind dog smells that bring you here to this article.

Mouth Odors. Yes, dogs get bad breath too. Particularly stinky breath could indicate an infection in a tooth, or more seriously, it could be a sign of kidney disease or diabetes.

Skin Folds. Breeds like Pugs or Shar-peis can start to smell bad because of dermatitis in their skin folds, so make sure you clean the folds regularly.

Ear infections. Yeast and bacterial infections in the ear can be stinky.

Bad Gas. This shouldn’t require any explanation, but here goes. If your dog’s farts can clear a room, there’s a good chance it’s eaten something it shouldn’t have. Unfortunately, there’s also a chance it indicates a serious health problem.

Avoid the Need for an Air Purifier for Dog Smells!

If you don’t have a stinky dog, you won’t need an air purifier to help remove dog smells.

So what can you do to avoid the situation in the first place?

Make sure you regularly bathe and groom your dog; just be sure not to bathe it too often. 

According to the American Kennel Club, over-bathing your dog can strip the oils from its skin and fur.

Most dogs should be bathed every month or so, but use some common sense.

Dogs with long, lush coats require more frequent baths, but shorter-haired dogs can go longer between baths.

Waterless dog shampoos on the market can be used in between— if spot cleaning is necessary. 

This is especially beneficial for dogs that have the skin folds mentioned above.

Finally, you might consider using — very lightly — baby powder or cornstarch. Both can absorb odors.

Does an Air Purifier Help with Dog Smell? Filters Matter!

As mentioned, if you need an air purifier that helps with dog smell, you need an air purifier with carbon filters. 

It could be a carbon filter paired with a HEPA filter or a carbon filter on its own.

HEPA filters and carbon filters have two entirely different processes. Let’s start with carbon filters.

Carbon Filters — What Are They and How Do They Work?

Carbon filters — also known as activated carbon or charcoal filters—can trap odors. 

This is done through absorption, but it’s a bit different than the absorption you might be familiar with.

In this case, molecules attach to the outside of the filter instead of soaking into it. 

The higher the quality of the filter, the more porous it will be. 

And the more porous it is, the better it can trap contaminants since the increased porosity also increases the amount of surface space.

And while you’re here because you’re interested in its ability to remove pet odors, a carbon filter can also remove the following:

  • Cooking odors
  • Mildew odors
  • Musty smells
  • Smoke

But it doesn’t stop there. Carbon filters also remove harmful VOCs (Volatile Organic Compounds). These are gases that certain liquids or solids emit into the air. 

They typically include a variety of chemicals, and some of them may have either short or long-term serious health effects.

Here are some VOCs that a carbon filter can remove:

  • 1,4-dichlorobenzene 
  • Acetone
  • Acrolein
  • Benzene
  • Ethanol
  • Formaldehyde
  • Methylene chloride
  • Toluene
  • Xylene

I don’t know about you, but to tell the truth, I don’t know what most of these are. 

What I do know, however, is that I probably don’t want to be breathing them in.

Who Should Have an Air Purifier with a Carbon Filter in Their Home?

Anyone who smokes or lives with a smoker, has a damp or musty basement, or owns a pet should invest in an air purifier with a carbon filter in their home.

But what if you want to remove airborne contaminants as well? That’s where the HEPA filter comes in.


HEPA Filters — What Are They and How Do They Work?

We hear a lot about HEPA filters because they’re so freaking awesome! Yeah, let’s dial that back a little bit.

Yes, HEPA filters are, but they’re only fantastic at what they can do – capturing and trapping solid airborne particulates. 

And as you probably know, odors are not solid.

HEPA filters undergo stringent testing and certification to be classified as 99.97% effective and efficient at removing airborne particles down to 0.3 microns in size. This is a guarantee.

So what solid airborne particles are included? 

Here’s a short list:

  • Allergens
  • Dust
  • Mold
  • Mold spores 
  • Pet dander
  • Pollen
  • Some bacteria
  • Some viruses

The good news is if you live in a household where you need an air purifier that will help with dog smells and can remove a variety of airborne particulates, there is a solution.

Air purifiers that come with multiple filters are very common. 

Specifically, multiple filters of a different type — so at least one HEPA filter and one carbon filter in the same unit.

That combination means you can clean your home of various pollutants.

Using an Air Purifier Will Help with Dog Smells, but Try These Too

Now that you understand what type of air purifier will help with dog smells, let’s talk about a few other measures to freshen up the air in your home.

Odor Eliminators

There are several things that naturally absorb odors, so you can give your air purifier a boost in helping remove dog smells. 

Place large bowls of your odor eliminator of choice where it’s most needed.

  • Baking soda
  • Coffee grounds
  • Oats
  • Tea
  • Vinegar

But don’t stop there. Here are some other things you can do.

Tips to Freshen the Air

These are general tips to help remove household odors. Still, they can also be used with your air purifier if you’re targeting dog smells.

These aren’t odor-absorbing materials like those mentioned above, but doing the following will help freshen your air.

First, open windows whenever possible! Then try some of these:

  • Add a few drops of essential oil to your HVAC filter
  • Put ground citrus peels in the garbage disposal
  • Neutralize carpet smells with baking soda
  • Simmer something aromatic on the stove
  • Put vanilla extract or essential oils on cotton balls

Does an Air Purifier Help with Dog Smell? – FAQs

What’s the best pet odor eliminator on the market?

Results will vary, but you can try Angry Orange Pet Odor Eliminator.

What is the best dog shampoo to get rid of the dog smell?

Rocco and Roxie Dog Shampoo for all Dogs and Puppies.

Should you wash your dog’s face?

Yes. Especially if your dog’s face has clumps of dried food on their faces.


Does an Air Purifier Help with Dog Smell? – Conclusion

So yes, there is good news for those of you with a stinky pet. 

Getting an air purifier will help with the dog smell.

Just remember that all air purifiers are not created equal. 

More specifically, all filters are not created equal.

To eliminate odors, you need an air purifier that has a carbon filter. 

And if you’d also like to remove airborne particles like your dog’s dander and hair, get an air purifier with dual filters – a HEPA filter and a carbon filter.

Does a Dyson Air Purifier Detect Carbon Monoxide?


I’ve seen several people asking if a Dyson air purifier detect carbon monoxide. Or if purifiers, in general, can detect or remove carbon monoxide. 

And I’ve seen a variety of answers.

Looking for the correct answer? Then here you go.

Yes. The Dyson air purifier does detect and absorb carbon monoxide. Or at least the Dyson Pure Hot + Cool Link does. 

The HEPA filter in this unit is in a sealed glass. It can absorb a variety of household gases, including carbon monoxide. 

Dyson has confirmed this information. But for some reason, the information is not freely available on their website, product descriptions, or even the user manual for the Dyson Pure Hot + Cool Link.

But now that that’s out of the way, are you looking for an air purifier that does detect CO?


Monitoring and Detecting Carbon Monoxide in the Home

Carbon monoxide has been dubbed the silent killer since people often die unaware that they’re being slowly poisoned.

It has no odor or color. It’s virtually undetectable. And it’s just as dangerous for your pets.

The symptoms of carbon monoxide poisoning include:

  • Chest pain
  • Confusion
  • Dizziness
  • Headache
  • Nausea
  • Vomiting
  • Weakness

If enough carbon monoxide is in the air, these symptoms can hit within two hours. 

High levels will lead to unconsciousness and eventually death.

Carbon monoxide symptoms in dogs include:

  • Bright red lips, gums, and ears
  • Difficulty breathing
  • Drowsiness
  • Sudden changes in behavior, such as aggression or anxiety
  • Uncoordinated movements
  • Vomiting

Carbon monoxide symptoms in cats include:

  • Depression
  • Difficulty breathing
  • Dizziness
  • Lethargy
  • Loss of hearing
  • Loss of stamina
  • Nausea
  • Red skin around the nostrils, lips, ears, and genitals
  • Seizures
  • Uncoordinated movements
  • Vomiting
  • Weakness

Note that in any situation, including humans and pets, the smaller the body, the quicker symptoms appear. 

The symptoms in a baby could appear within minutes instead of hours, and in a small dog or cat, much quicker than a large dog.

That’s why every home should have a carbon monoxide detector of some kind. 

It’s just as important as the smoke detector. Some might say even more important than a smoke detector since there are no clues to its presence. 

You can see, feel, hear, and smell fire.

Dyson Pure Hot+Cool Link Features

Dyson has 4 purifiers in their lineup, plus the Pure Hot+Cold Link, which is basically a purifier in steroids. 

It doesn’t just clean your air; it also raises or lowers the temperature in your room.

Here’s a quick rundown of the features.

  • A state-of-the-art, 2nd generation filter with a 360° Glass HEPA filter made from borosilicate microfiber and pleated 333 times. The 360 glass filtration will capture odors and gases—including carbon monoxide—while the HEPA filter will remove 99.97% of particles 0.3 microns in size. 
  • Long-range projection and smooth oscillation—up to 70%—ensure that the air of your entire room is circulated and purified. 
  • Two airflow modes mean you can focus it where you need it most. 
  • Depending on the season, you can heat or cool your air while you purify it. 
  • Remote control. 
  • Certified by the Asthma and Allergy Foundation of America.

Should a Dyson Air Purifier That Detects Carbon Monoxide Replace Standard CO Detectors?


A Dyson air purifier that detects carbon monoxide — or any Dyson product — is a pretty big investment. 

And you may feel that having one in your home is sufficient for purifying your air and detecting a variety of VOCs and gases.

But should it replace standard CO detectors?

The answer is no. CO detectors are supposed to be placed throughout the home in various locations. 

Experts say, at the very minimum, one should be installed on each level of the home. 

If not on every level, then at least every level with a fuel-burning appliance like a furnace, stove, or fireplace.

Additionally, a CO detector should be placed in hallways outside of bedrooms.

Even if your Dyson air purifier is placed in a central location, it isn’t capable of detecting carbon monoxide until it reaches the filter. 

And for some, that may be far too late.

The Best Placement for Your Dyson Air Purifier

Whether or not a Dyson air purifier detects carbon monoxide — I’m not sure if all of them do — where’s the best place to situate one in your home?

To some extent, where you place an air purifier can have a larger impact on your home than the air purifier itself. 

In fact, tests have shown that it’s possible to increase the overall efficiency of an air purifier by about 20% if you’ve placed it in an optimal position.

The flip side is if you place it somewhere, like in a corner or perhaps behind some furniture, you’ll see a decrease of about 50% in its air purifying capacity.

So where should it go? 

Consider each point to help determine where you should or should not put your air purifier.

Largest concentration of pollutants. Take some time and decide which area of your home generates the most pollutants. 

That could be odors, smoke, mold, a pet’s bed or litter box, or something else.

Elevate it off the ground. Putting a purifier 3 to 5 feet off the ground allows you to capture air movement in both directions — air moves horizontally and vertically. 

Of course, if you have a sizeable floor-standing model, the fan may already be at that height.

High airflow areas. Give your air purifier as much help as possible by positioning it somewhere with increased airflow.

Don’t try to hide it. Your air purifier must be out in the open, so don’t put it in a corner, behind your furniture, or any other out-of-the-way place. 

None of these places will have sufficient airflow.

Avoid humidity. Your air purifier shouldn’t be in a kitchen, laundry room, or bathroom. 

Moist air is heavier and will reduce the capacity and efficiency of the filters. This is especially true with HEPA filters.

If you have a mold situation in a high-humidity spot, consider a dehumidifier instead of an air purifier.

Don’t get too close to your electronics. This is especially true with high-end, state-of-the-art air purifiers like Dyson. 

Keep it at least 5 feet from anything that might produce electronic interference.


Does a Dyson Air Purifier Detect Carbon Monoxide? – FAQs

What VOCs does Dyson detect?

Most Volatile Organic Compounds can be detected by a Dyson air purifier, including formaldehyde down to 0.1 microns.

What air purifiers remove carbon monoxide?

Along with Dyson, Mila, and Magic Clean air purifiers can also remove carbon monoxide.

Should I leave my Dyson air purifier on all the time?

Yes. You should run your Dyson air purifier 24/7 to achieve and maintain the highest possible level of air quality.

Your Dyson Air Purifier Detects Carbon Monoxide!

So there you have it. 

Despite many sites saying the opposite, a Dyson air purifier does detect carbon monoxide. In fact, it’s not the only brand to do so.

However, there are a few things to consider. 

The ability to detect CO comes with a premium price tag. You still need to have standard CO detectors placed throughout your home.

Will an Air Purifier Help with Cat Allergies?


You love your cat but hate what its dander does to you. Will an air purifier help with cat allergies?

Yes, an air purifier will help remove pet hair and dander from the air – two of the most common allergens.

The very purpose of an air purifier is to remove allergens and contaminants from your air, so it’s doing its job.

That’s great news for cat owners who are also allergic to cats – but it isn’t the whole story. Not all air purifiers are created equal.

So what more do you need to know? Glad you asked!


Is it True? Does an Air Purifier Help with Cat Allergies?

It’s true! Using an air purifier helps with cat allergies.

Not sure if that’s the truth or fiction? Good. Don’t take things at face value!

Here’s some proof. 

The United States Environmental Protection Agency has a page on indoor air quality. To be more specific, they address HEPA filters.

HEPA stands for High-Efficiency Particulate Air. HEPA filters are tested and certified to remove 99.97% of the following:

  • Bacteria
  • Dust
  • Mold
  • Pollen
  • … and any airborne particulates with a size of 0.3 microns

It’s that last line that’s really important. 0.3 microns is roughly the size of 1/3000th of a pinhead. 

Pet dander and hair—more specifically, your cat’s hair and dander—will get trapped by a HEPA filter.

Considering that 65% of US households have at least one pet, and 30% of those people are allergic to cats or dogs, that’s very good news.

But wait. I know some skeptics and people smart enough to check facts are out there.

And the fact is, pet dander can be as small as 0.1 microns—smaller than 0.3 microns. 

So how dare we claim a HEPA filter can capture pet dander, right?

Air Purifier and Cat Allergies: Understanding HEPA Filters and Particle Sizes

As is widely claimed, a HEPA filter is guaranteed to have 99.97% efficiency in removing particles that are 0.3 microns or larger. 

So what’s the deal with claiming it can capture particles as small as 0.1 microns?

In reality, HEPA filters can capture particles of all sizes — both smaller and larger than 0.3 microns.

How is this possible?

Part of the problem is that we think of filters as being like a sieve, with holes that either allow something through or block it. 

But that’s only partly true. In reality, a HEPA filter uses several different methods to capture even the smallest of particles.


Here’s a breakdown of how a HEPA filter captures particulates. And sorry, but this will get a little bit like science class.

  • Sieving. The filter acts like the sieve mentioned above, where anything larger than a specified size can’t get through.
  • Inertial Impaction. This happens when a particle has inertia which moves it in a specific direction— in this case, toward the filter and its fibers. Particles that are 0.5 to 5 microns will get trapped in the fibers.
  • Interception. These particles aimlessly float through the air until they’re intercepted by the filter. Any particles that are 0.1 to 1 micron will stick to the fibers.
  • Diffusion. The tiniest particles, measuring smaller than 0.1 microns, bounce off gas molecules — remember, the air is gas, eventually landing on and sticking to the filter’s fibers.

So pet dander, which is 0.1 microns in size, can still be filtered out of your environment.

Cat Allergies, Specifically Dander and Hair

First up, let’s talk about the causes and symptoms then we’ll get into more information on how air purifiers help with cat allergies.

A lot is said about cat hair, but is it the hair that triggers the allergy?

No. It’s what’s collected in the hair. More specifically, dander. 

And if you want to get even more specific than that, the proteins found in the dander trigger the allergy.

Dander, a dead skin cell, carries this protein, as does the cat’s saliva and urine. 

Your cat’s hair not only collects and holds onto the dander, but it can also carry a variety of other allergens, such as dust mites, mold, and even pollen.

This is why people are most allergic to furry animals. But anything with hair or feathers can trigger the same allergic reaction. 

As soon as the protein in the dander reaches your respiratory system, eyes, or skin, it can trigger an allergic reaction.

Pet dander is microscopic, so it floats through the air unnoticed. However, thanks to its jagged edges, it will stick to anything it lands on.

That could be your upholstery, your draperies, your clothes, you’re bedding, and even your body.

Air Purifiers Help with Cat Allergies, but They Could Use Some Assistance

Now that we’ve helped you to understand how your air purifier can help with cat allergies, how about taking it one step further?

You can do a few things in your home that will further improve the air quality for allergy sufferers. 

So apart from using an air purifier with a HEPA filter, take a holistic approach and consider doing the following:

  • Vaporizers and humidifiers aren’t necessarily your friend. Allergy sufferers should keep indoor humidity levels below 50%.
  • Air purifiers aren’t the only appliances that come with a HEPA filter. Consider purchasing a vacuum cleaner with a HEPA filter to help further reduce dust, pet dander, pet hair, and other allergens.
  • Don’t allow anyone in the home to smoke.
  • Pollen sticks to your clothes, so during allergy season, be careful not to track it into your home on your shoes or clothes. Take those shoes off at the door.
  • Don’t groom your pet inside. Cut down on the amount of hair and dander in the air by taking your pet outside to groom them.
  • Keep mold under control in bathrooms, basements, and wherever it may grow.

Will an Air Purifier Help with Cat Allergies? – FAQs

What is the fastest way to get rid of cat dander?

Brush your cat daily with a soft brush, but do it outside.

What neutralizes cat dander?

You can try dander shampoos such as Tropiclean Dander Reducing Waterless Cat Shampoo.

Can I build immunity to cat allergies?

Do You Need an Air Purifier in Every Room?


If you’re someone who wants to make sure the air you breathe at home is clean, you may be wondering if you need an air purifier in every room.

After all, most of us appreciate a clean home and someone – or something – that’s doing their share in keeping it that way. 

So you dust, clean, and vacuum, but do you need an air purifier in every room too?

The short and sweet answer is no. You don’t need an air purifier in every room—at least in most cases. 

Having said that, there are several factors to consider. For example, do you have a tiny air purifier that only covers the area of a typical-sized powder room?

Let’s dig deeper into why you may or may not need an air purifier in every room. 

But first, a little air purifier 101 is in order, as it will help you understand why you may or may not need multiple air purifiers.

Size Matters: Do You Need an Air Purifier in Every Room?

When asking yourself if you need an air purifier in every room, there are two very important factors you’d want to consider: the size of your air purifier and the size of your home.

The Size of your Air Purifier

How big is your air purifier, and how big is your home or the rooms in which you want to put a purifier?

This isn’t rocket science, so you should know that just like homes come in various sizes, air purifiers do too. 

You can find models that will cover the area of a small room to whole home air purifiers—but the latter are typically attached to your HVAC.

Regardless, every air purifier will have the coverage area listed on the packaging. 

If you’re buying something used, Google the model number, and you should be able to find out the coverage.


The Size of your Home

Next, the size and layout of your home.

Do you have a home with many small—or large—rooms, or is it more of an open concept with no actual rooms? 

Where do you spend the most time? Do you have pets, and where do they spend most of their time?

This should help you determine the priority rooms you’d want to put your purifier in.

Choosing the Right Size Means You Won’t Need an Air Purifier in Every Room

Choosing the right size, to begin with, means there’s a good chance you won’t have to question whether you need an air purifier for every room.

Since air purifiers are available in four basic sizes, it’s easy to narrow down the right size for you and your home.

  • Small purifiers are suitable for rooms and spaces up to about 200 square feet
  • Medium purifiers will work for rooms or areas between 200 and 400 square feet
  • Large air purifiers are best when you need coverage for 400 to 1500 square feet
  • Whole home air purifiers will clean the air in your entire home using your ductwork

Based on that, assuming you’re not only looking for a purifier for one specific room, a large air purifier will be sufficient for a large apartment /condo or smaller house.

Figure out the square feet you need or want to cover and work from there.

Air Purifier Placement

As mentioned above, the best place for an air purifier is where your family spends the most time. 

It could be in a media room, the kitchen, a home office, or perhaps a bedroom.

But if you have multiple small rooms in your home that would benefit from cleaner air, deciding to have an air purifier in every room makes more sense.

Once you’ve determined where you’d like to place your air purifier, it’s time to do some measuring.

Air Purifier Coverage Area


Since some people are completely math challenged — raising my hand — we’ll follow the KISS (Keep It Simple Stupid) method so everyone will understand.

Air purifier coverage will be based on square feet or square meters, depending on where you live. 

Fortunately, calculating square feet is ridiculously simple — especially for just one room.

Grab a measuring tape and measure the length and width of your room. 

If your room is not a perfect square or rectangle, for example, there’s an alcove, take two measurements and add them together. 

The length times width of the room plus the length times width of the alcove—or whatever.

For example,

Room = 10 x 13’ = 130 sq ft

 Alcove = 2 x 3’ = 6 sq ft

 Total = 136 sq ft

If you hope to clean the air of two or more adjoining rooms, use the same method as above, adding the square footage of each room to come to your final total.

Assuming you’re hoping to purify the air of your entire apartment or home, you probably already know your square footage.

If you’re basing your calculation on the square footage of your home, keep in mind that not everything is always included in this measurement. 

Any finished space like staircases and closets would be included, but porches, garages, and unfinished basements likely aren’t.

And one more thing to keep in mind. When you see the coverage area on the box or literature of an air purifier, it’s not an exact number. It’s just an estimate. 

And depending on the layout of your area, it may be more or less efficient as it gets to the outer limits of the coverage area.

Now that you’re able to determine what size air purifier you need — and whether or not you need an air purifier in every room — there’s still something else you need to consider.

CADR Ratings—What’s That All About?

Another very important consideration is the CADR rating.

CADR is an acronym for Clean Air Delivery Rate. 

Essentially, that means the volume of filtered air the purifier can exchange – how much dirty air gets replaced by clean air in a specified timeframe.

The higher the rating per pollutant, the more it will remove.

If the air purifier you already own or the one you’re thinking of buying doesn’t have this rating, it is neither tested nor certified—and there’s a very good chance it doesn’t meet industry standards.

What Pollutants Do You Need Your Air Purifier to Remove?

Just as air purifiers can clean air in smaller or larger areas, different models also come with different features and filters that will clean different things from the air.

So what do you need to be cleaned from your air? And what are purifiers capable of removing from the air? Will you need an air purifier in every room—each targeting different airborne pollutants?

If that works best for you, go for it.

Here’s a breakdown.

HEPA Filters

Assuming you choose an air purifier with a HEPA filter, these highest-rated filters can capture 99.97% of airborne particles up to 0.3 microns. 

In perspective, 0.3 microns is smaller than a strand of fine human hair. 

And they can remove the following:

  • Bacteria
  • Cigarette smoke
  • COVID-19 (according to the National Library of Medicine, COVID particles range from 0.06 to 0.14 microns)
  • Dust
  • Mold spores
  • Pet dander
  • Pollen
  • VOCs (volatile organic compounds)
  • Wildfire smoke
  • …and more

You may not need an air purifier that removes smoke — from tobacco or wildfires — but you might need something that removes pet dander. Or you may have someone in the house who has a pollen allergy.

So you have an option. 

You can buy a purifier with a top-rated HEPA filter that will remove any and everything, but it will cost you. Or you can choose one with the lower MERV-rated filter that targets what you need and doesn’t cost as much.

But wait. There’s another, even better option.

Most air purifiers only clean or purify the air; they don’t sanitize it. And depending on the severity of a family member’s need for clean air, sanitizing may be required.

If you have a central system, the best option for this is a UV light attached to it. 

Portable air purifiers offer this ability as well. Another option is an ionizing model.

True HEPA vs. HEPA

Don’t get caught up in marketing ploys. 

Marketing aims to make you buy a product, not necessarily tell the truth.

If you’re buying a product headquartered in a country with the highest of regulatory standards—note this doesn’t mean the product is also manufactured in that country—there must be a measure of truth in marketing statements. 

But not the whole truth and nothing but the truth.

Be suspicious if you’re looking at cheap air purifiers on Amazon or any other online retailer. 

If you’ve never heard of the brand name, do some research. There’s a good chance that the product is cheap for a reason. 

There’s also a good chance any claims made in their marketing material could be outright lies.

Does this mean that any product developed and manufactured in some country that doesn’t have the stringent regulatory demands most western countries have should be ignored?

No. It just means you need to do some research. 

Western manufacturers operate under strict regulations—but other parts of the world? Not so much.

So just because a product says the filter is a HEPA filter or True HEPA doesn’t mean it is. And True HEPA is a marketing or branding term. 

Assuming it’s a genuine HEPA filter, it’s the exact same thing as any other genuine HEPA filter.

The important word there is genuine.

Don’t buy anything with a name such as HEPA-Like, HEPA-Ready, HEPA-Type, etc. 

A legitimate, genuine HEPA filter will be labeled and signed off. 

This lets you know it has passed testing and inspection and can do the job it claims to do.


Do You Need an Air Purifier in Every Room? – FAQs

If you’re wondering whether or not you need an air purifier in every room, there may be other questions in your mind as well. Maybe one of these!

Is it okay to leave an air purifier on all day?

Yes. Leaving your air purifier running 24/7 is optimal.

Is it okay to sleep next to an air purifier?

Yes, it’s okay. However, depending on the dB rating, it may disturb your sleep.

Do air purifiers make a room smell fresh?

Air purifiers can reduce or remove some odors, but there is no guarantee they will completely freshen your air.

So, Do you Need an Air Purifier in Every Room?

Having an air purifier in every room is welcome and beneficial, although not really necessary. But ultimately, the answer to that will depend on your space and needs.

If you’re still in the research stage, knowing the relevant details about your room and the air purifier you’re eyeing is essential in buying the right one for your needs.

So be sure to follow the guidelines above!

How Long Does an Air Purifier Filter Last?

different filter - how to clean holmes air purifier

How long does an air purifier filter last?

We know that air purifiers are costly, especially if you buy a top-of-the-line air purifier with high-quality HEPA filters. 

The last thing you want is to purchase a hundred-dollar air purifier and then have it break down after six months.

In reality, air purifiers usually use several different filters, each with a different lifespan. 

And there are a few tips and tricks that you can use to make sure your air purifier filters last as long as possible.

How Long Does an Air Purifier Filter Last – HEPA Filters

One of the most common filters that air purifiers use is the High-Efficiency Particulate Air or HEPA filter. 

These filters can filter out 99.97% of particles at 0.3 micrometers in size, making them one of the most popular filters for people with allergies.

Their ability to filter out tiny particles also made them a popular tool during the pandemic. 

They can pull virus-containing droplets out of the air and contain them before transmitting an illness to someone else.

As a HEPA filter is used, it will slowly become saturated with particles that it pulls out of the air. As the filter becomes saturated, it stops functioning and must be replaced.

The average recommendation is changing your HEPA filter every 18 months to 3 years

This will help to ensure that your HEPA filter is still doing its job and filtering your air efficiently.


How to Know When to Change a HEPA Filter

There are two ways to check if your HEPA filter is still working without calling in a team of professionals. 

You can track how old the filter is and look at the filter’s appearance.

On average, a HEPA filter must be changed out every 18-36 months, depending on how many hours per day you are running it. 

If your HEPA filter has already been used for a year, you can change it to maintain the high air quality in your home.

If you’re not sure how old your HEPA filter is, you can get a lot of clues about how well it’s functioning just by looking at the filter. 

If the filter has turned yellow or gray or has a thick layer of dust and other particles stuck to it, it’s probably time to change your filter.

Suppose the filter still looks relatively new and has no significant buildup. In that case, you’re probably good to keep using your filter for another several months.

One last option is having a professional team come out and check on the filters. 

They can tell you whether the filter is still cleaning your air and if air quality is being maintained.

How Long Does an Air Purifier Filter Last – Carbon Filters

Some air purifiers also use a carbon filter placed right before the HEPA filter. 

The purpose of this filter is to absorb odor-causing molecules that are too small to be trapped by the HEPA filter.

Deodorizing filters use activated carbon to absorb odors. 

The spaces between the carbon molecules can absorb even the tiniest particles, making them a great choice if you struggle with odor in the home.

On average, carbon-based air purifier filters will last anywhere from 6-12 months in an air purifier before they should be replaced. 

Just like with HEPA filters, carbon-based filters continue functioning based on how saturated they are.

Once the activated carbon in the filter becomes saturated, it will stop absorbing odors.

How to Know When to Change a Deodorizing Filter

Like with HEPA filters, the easiest way to know it’s time to change your deodorizing filter is by tracking how long you’ve been using it.

Once you hit the one-year mark, it’s time to throw your deodorizing filter out and purchase a new one.

Another easy way to know that it’s time to change your deodorizing filter is by smelling the air. 

If you notice that odors start to build up again when they were previously well-controlled, it’s time to get a new deodorizing filter.


How Long Does an Air Purifier Filter Last – Pre-Filters

When you search for “How long does an air purifier filter last?” you’ll likely find answers about HEPA and deodorizing filters. 

However, that is not the only filter that your air purifier contains.

Most air purifiers also contain a filter layer called the pre-filter. 

This pre-filter is made from a mesh-like material designed to catch larger debris and prevent it from clogging your other filters.

Since pre-filters can accumulate large debris so quickly, most are designed to be reusable, unlike the more delicate internal filters.

You’ll want to remove and clean your pre-filter every 2-4 weeks, possibly more if you deal with a lot of pet hair clogging your filter. 

To clean your pre-filter, gently brush it off, vacuum it, or rinse it under running water.

Eventually, after many uses, your pre-filter will begin to break down and should be thrown away and replaced. 

You’ll know that your pre-filter needs to be replaced as the material stretches out or when you notice small holes in the filter.

Maximizing the Lifetime of Air Purifier Filters

All filters will give out and need to be replaced at some point. 

However, by following a few simple guidelines, you will be able to maximize the lifetime of your air filters and save money by not having to repurchase them constantly.

Use a Pre-Filter

The best thing you can do to maximize the lifetime of your disposable HEPA and deodorizing filters is to use a pre-filter.

The purpose of a pre-filter is to filter out the larger debris, like hair and larger dust particles. 

If these particles are not filtered out, they will rapidly clog your HEPA filter, resulting in prematurely replacing it.

To keep your pre-filter functioning correctly, you’ll need to clean it out every 2-4 weeks to remove all of the debris that it has accumulated.

Pick a Large Air Purifier

When you pick out your air purifier, try to select a model that is larger than necessary. 

This will ensure you can run your air purifier on one of the lower settings while maintaining good air quality.

When you constantly run your air purifier on the highest setting, it can create unnecessary drag. This can damage the filter and result in having to replace the filter more quickly.

Using a smaller air purifier also means smaller air filters that will fill up more quickly. 

A larger air purifier will have more space in its filters for debris and will take longer to need replacements.

Purchase High-Quality Filters

When you purchase your next set of air purifier filters, don’t automatically go for the cheapest filter available. 

Yes, this filter will have the lowest upfront cost. However, the cost will add up as you have to replace the filter more frequently.

High-quality air purifier filters are made from a denser material and typically have more surface area. 

This means that more filter must be “filled up” before it needs to be replaced.

Use an Air Purifier with Filter Monitoring

For most types of air purifier filters, there is an extensive range of times when it’s recommended to change them. 

Some companies say that your air purifier filter can last several years. In contrast, others say that an air purifier filter only lasts for a short time and should be changed every six months.

To avoid changing a filter too soon and wasting money on an unnecessary replacement, try purchasing an air purifier with filter monitoring.

These air purifiers will monitor how easily the air flows through the filter and how long it’s been since you installed it.

Once the airflow decreases, the filter will signal that it is time to change your air filter. 

This technology will help avoid unnecessary filter changes and help you remember to change your air purifier filter regularly.


How Long Does an Air Purifier Filter Last? – FAQs

Can you leave an air purifier on at night?

Not only can you leave an air purifier on at night, but you should also leave your air purifier on all night. 

This will prevent contaminants from building up in the air and prevent you from waking up with allergy symptoms.

How do I know if an air purifier is working?

You can tell if your air purifier is working by checking the air quality monitor that most air purifiers have. 

If the air quality is consistently in the blue or green zone, depending on the brand, your air purifier functions as it should.

You should also be able to tell based on your symptoms. 

If your allergy symptoms have significantly improved, your air purifier works properly and filters contaminants out of the air.

Can air purifiers improve sleep quality?

If you suffer from allergy symptoms while sleeping, using an air purifier can significantly improve these symptoms. 

Reducing your allergy symptoms can help you to sleep more deeply and stay asleep longer.

Final Thoughts: How Long Does an Air Purifier Filter Last?

How long an air purifier filter lasts will depend on the type of air purifier filter that you’re using and how frequently you use it.

HEPA filters can usually last for around a year before they need to be replaced. 

Deodorizing filters do not last quite as long and usually need to be replaced every six months or when they stop working.

Pre-filters rarely need to be thrown out and replaced. 

However, they should be cleaned every 2-4 weeks to eliminate any accumulated debris.

Is An Air Purifier Safe for Birds? What You Need To Know


If you are a homeowner and bird parent, you probably wonder, “is an air purifier safe for birds?”

This is, indeed, a valid concern. After all, it’s not only your bird’s health that could potentially benefit from air purifiers but yours, too!

Unfortunately, though, as with so many things in the HVAC industry, there isn’t a single, clear-cut answer. 

Despite that, you’ll find websites that unequivocally say they are safe. However, that’s not necessarily true.

In the end, you will need to research a specific air purifier model and the technology it uses to be able to say with certainty that it’s safe for your bird. 

But don’t worry; we won’t leave you in the dark.

The following will provide helpful information to help you make a wise decision that won’t ultimately be bad for your pet.


Are Air Purifiers Safe for Birds—And do Bird Owners Really Need One? 

Assuming air purifiers are safe for birds, do you really need one? 

For yourself, and maybe for your bird as well?

Bird Dander Can Be Dangerous to Humans

Bird dust and dander — and pet dander in general — is potentially dangerous, especially to people who are allergic to it and to anyone with asthma. 

Breathing in the dander can trigger an immune response that can lead to, at the very least, a sore throat, itchy or watery eyes, and itchy skin.

A condition called Alveolitis, which causes the lungs to become inflamed, is also possible. 

Another disease, Psittacosis, is caused by a bacterium called Chlamydia psittaci, carried by birds. 

This can cause severe illness in the elderly if and when they inhale bird dust from feathers. 

So once you’ve determined that an air purifier is safe for birds, having one in your home could decrease your chances of picking up several illnesses.

Human Homes Can Be Dangerous for Birds

On the flip side, while we may feel that we live in a safe environment, it may not be so safe for a bird.

If you have a bird and there’s a smoker in the home, purifying the air is important, especially if you have cockatiels, cockatoos, or African greys.

Birds are small — at least in comparison to us — but their respiratory system handles more air per their body weight than humans.

This makes them susceptible to toxins in the air, including Teflon, PTFE, cleaning chemicals and fumes, air fresheners, their own dander, fecal matter, cigarette smoke, and carbon monoxide.

Yes, the air outside is likely dirty and full of pollution. Still, to some extent, the air outside is continuously recycled. 

Plus, rain and wind have added benefits to cleaning the air.

So once you’ve determined that an air purifier is safe for birds, using one can be as beneficial for them as it is for us.


Choosing an Air Purifier Safe for Birds

Now that we’ve concluded that it’s probably a good idea for you and your bird to have one, it’s time to narrow down which air purifier is safest for birds.

This doesn’t mean you don’t need to do your due diligence when choosing an air purifier. 

Still, it should simplify your selection process by helping you narrow your choices.

Remember, if you see an air purifier manufacturer claiming that air purifiers are safe to use, they may simply be saying that their brand or model is safe. Or it may be nothing more than a marketing ploy.

Electronic vs. Mechanical Air Purifiers

At the highest level, there are two types of air purifiers: electronic and mechanical. 

Mechanical air cleaners pull air through a filter that traps airborne particles. Better yet, they’re highly reliable and do their job without producing an air pollutant — ozone.

Electronic air cleaners and purifiers work differently. They use electricity to charge and trap air particles. 

There are three main types of electronic air cleaners — electrostatic precipitators (ESPs), ionizers, and ozone generators.

Electrostatic precipitators use negative and positive charges to collect air particles into plates that eventually need to be cleaned. 

Ionizers collect particles, clean them, and deposit them in the room. 

Finally, ozone generators, typically only used in construction areas, produce ozone to clean spaces.

In addition to the three main types of electronic air cleaners and purifiers, some use ultraviolet technology to sanitize the air.

Of the two main types of air purifiers — mechanical and electronic — mechanical filtration is recommended for pet owners, especially birds. 

This isn’t to say that electronic air purifiers are ineffective; it’s just that ozone and ionized contaminants are potentially harmful to your family and your bird.

Mechanical air purifiers have a simple filtration system comprising a fan and at least one filter. 

The fan circulates the air, and the filter catches and traps airborne particulates as they pass.

Which Mechanical Air Purifiers Are Safest for Birds?

Now that we’ve determined that mechanical air purifiers are safest for birds, let’s discuss filters.

All mechanical air purifiers are not created equal. 

The most essential component of the purifier is the filter since its job is to trap airborne contaminants. 

Essentially, your air purifier is only as good as the filter it contains.

There are many filters on the market, but we will focus on HEPA filters and filters with a MERV value rating.

Since the MERV rating scale is a little more complex, let’s start with that.

What is the MERV Rating System?

MERV is the acronym for Minimum Efficiency Reporting Value. 

By means of a value system between 1 and 16, tested air filters are rated at their efficiency when trapping air particles of various sizes.

The standards for the tests were developed under and implemented by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). 

The latest standard — ANSI/ASHRAE Standard 52.2 — has existed since 1999.

Test results are based on very stringent testing.

The least efficient rating for a filter is MERV 1. A filter will trap carpet fibers, pollen, and dust mites at this value. 

However, it’s only 20% efficient and will only remove particles between 3.0 and 10.0 microns.

What’s a micron, you say?

Microns are teeny tiny. To be more specific, the 10-micron unit that a MERV 1 filter can capture is equivalent to 0.000393701 inches or .01 millimeters. 

To put that in perspective and help you visualize better, the size of the average pinhead is about 2.0 microns.

A low-value MERV-rated air purifier filter will likely be of little use to you or your bird. 

Instead, look for an air purifier with a higher-rated filter. 

For example, a MERV 16 filter.

At the other end of the spectrum from a MERV 1 filter, a MERV 16 filter can remove many more, much smaller, particulates from the air, like bacteria, airborne viruses, mold, tobacco smoke, and a variety of other pollutants.

Better yet, it will remove a minimum of 95% of all microns sized between 0.3 and 1.0, about 10 times smaller than what a MERV 1 filter can catch and trap. 

These would be very safe and effective air purifiers for your birds but are they the best option?

HEPA filters are even better.

What are HEPA Filters?

HEPA filters pick up where a MERV 16 filter stops. A HEPA filter is even better than the highest-rated MERV filter.

HEPA is an acronym for High-Efficiency Particulate Air. 

The testing filters go through to attain this certification isn’t even in the same stratosphere as what MERV-rated filters go through. They exceed the testing protocols that are in place to determine MERV certification.

HEPA filters are the only ones currently available that meet the stringent testing criteria necessary to be certified as having met a specific efficiency level. 

To be classified as a HEPA filter, it must have a minimum efficiency of 99.97 % at 0.3 microns.

And yes, a MERV 16 filter can also remove particulates as small as 0.3 microns. But that doesn’t tell the whole story.

The whole story is that a filter rated at MERV 16 will remove pollutants as small as 0.3 to 1.0 microns and remove 95% of them or more.

That sounds great, but you need to realize that it’s only guaranteed to remove 95%.

On the other hand, a HEPA filter is guaranteed to remove more–up to 99.97% of particles that are 0.3 microns. 

That sounds much better, doesn’t it?


Generally Speaking, Is An Air Purifier Safe for Birds?

Air purifiers can be safe for birds, especially mechanical ones. 

But there are a few other things to consider.

Many people aren’t as cautious or knowledgeable as they should be when plugging in an energy-intense appliance such as an air purifier. 

Plugging into an overloaded circuit could lead to an electrical fault or a short circuit, potentially starting a fire.

Obviously, a fire is dangerous for you and your family, your bird, and any other pets.

Additionally, while a mechanical air purifier with a fan and a filter is an advantage, that fan can also be a disadvantage. 

Be sure not to place it too close to your bird since it might cause a draft. This could be potentially hazardous to its sensitive respiratory system.

Air Purifier Safe for Birds – Conclusion

Wondering if an air purifier is safe for birds isn’t only for the birds but for your and your family’s health as well.

This is important.

Bird dust and dander are potentially dangerous, even more so if you have seniors in the home.

Additionally, birds have very sensitive respiratory systems; for the most part, they are trapped inside with whatever airborne pollutants are floating around your home.

Picking the Best Air Purifier for Baby nursery

Before choosing the best air purifier for your baby’s nursery, consider these key things:

Room size

First, the air purifier must match the nursery’s size. You don’t want a small device for a big room or vice versa.

Filter type 

Look for an air purifier that uses HEPA filters. These filters can help trap tiny particles like pet dander, mold, dust, and pollen that can trigger allergies or asthma in babies.

Noise level

A baby’s sleep is precious, so you don’t want an air purifier that will disrupt it. Look for an air purifier that operates at a low noise level, ideally under 50 decibels, so that it won’t wake your baby up.


Get an air purifier with automatic mode, air quality sensors, and filter replacement indicators. These features can help you keep track of the air quality and when it’s time to change the filters.


Safety is of utmost importance when it comes to your baby. Get an air purifier with safety features like a child lock or auto shut-off to protect your baby from potential hazards.

Air purification rate

The purifier’s CADR (Clean Air Delivery Rate) rate measures its cleaning performance. The higher the CADR, the more efficient the purifier is at removing pollutants from the air.


It’s also important to consider the ongoing costs of replacing filters and how often you’ll need to replace them.

Sure, you might find a cheaper air purifier, but if the replacement filters are expensive, it might not be worth it in the long run.

A good-quality air purifier typically costs between $70 and $250.

However, if you want a high-tech model that can clean a larger space, you need to budget over $500. So weighing all the options and finding the right balance between cost and quality is essential.

Overall, there are many options, which can be overwhelming. But, to simplify it, steer clear of air purifiers that generate ozone. 

Instead, focus on air purifiers that use ionization or UV light to purify the air. It’s a safer way to purify the air. 

So, when shopping for an air purifier, choose a filter-based option for a cleaner and safer breath of fresh air.

Also, do your research and read the product descriptions carefully to ensure you get the best air purifier for your baby’s needs.


Tips for Using Air Purifiers in a Baby’s Nursery

Do you want to keep the air in your baby’s room fresh and safe? 

Here are some tips to make sure the air purifier is working as it should:

Position the air purifier correctly

Place the air purifier in the corner of the room, away from the crib or play area. This will ensure that the purified air is distributed evenly throughout the room.

Use the right filter

An air purifier that uses HEPA filters can trap small particles like dust, pollen, and pet dander that trigger allergies in babies.

Keep the noise level low

 Your baby’s sleep is precious, so you don’t want something to disrupt it. So buy an air purifier that operates at a low noise level, ideally under 50 decibels, so that it won’t wake your baby up.

Use the auto mode

Many air purifiers have an auto mode, which adjusts the fan speed based on the air quality. This feature will help keep the air clean and healthy without you having to monitor the device constantly.

Clean or change filters regularly

Regularly cleaning or changing the filters will ensure that the air purifier works at its best and provides the highest level of air purification.

Monitor the air quality

Many air purifiers come with air quality sensors, which allow you to monitor the air quality in real time. This will indicate when the air in the nursery is clean and when it needs to be purified.

Make it safe

Safety should be your top priority for your baby. Look for an air purifier with safety features such as a child lock or auto shut-off to protect your baby from potential hazards.

Air Purifier Safety Precautions

Air purifiers have many advantages, but you should use them cautiously. 

Keep newborns and children away from all appliances, especially air purifiers. 

Child-proof your baby’s air purifier so they can’t play with it if you can. 

Also, follow the manufacturer’s guidelines and instructions before setting up an air purifier in your baby’s room.

FAQs on Air Purifiers for Baby Nursery

Do Air Purifiers Help Babies?

Yes, air purifiers are a must-have for babies! They help create a cleaner and healthier environment for your little one to grow in.

Is an Air Purifier a Good Idea for a Baby’s Room?

It depends on your family’s needs. 

If you or your partner have allergies, it’s best to keep allergens like dust mites and dander at bay. 

If not, it may not be as necessary, but it can still provide cleaner air for your little one to breathe in.

Which Is Better for a Newborn: An Air Purifier or a Humidifier?

Air purifiers and humidifiers both have their unique benefits. 

Air purifiers remove impurities and allergens, while humidifiers add moisture to dry air. 

For newborns, a humidifier can be especially helpful in alleviating stuffy noses and dry coughs.

Consider using both in your baby’s room, depending on your needs.

When Should I Use an Air Purifier for My Baby?

It’s a good idea to use an air purifier in a baby’s room if you have allergies or asthma, your baby has respiratory issues, or your home is in an area with high pollution levels.

At What Age Should I Use an Air Purifier in My Baby’s Room?

It’s recommended to use an air purifier in a baby’s room as soon as possible, especially during the first year of life when babies spend most of their time indoors. 

This will help provide them with a clean and healthy indoor environment.

Do I Need an Air Purifier if I Live Close to the Freeway?


Do I need an air purifier if I live close to the freeway?

As we know, high exposure to air pollution puts people at a higher risk of developing respiratory diseases and infections.

And if you live close to any highway of sorts, this should be a significant concern.

Many people live a stone’s throw away from the freeway. When they do this, they inhale more air pollution than people living in other areas.

This is why I suggest getting an air purifier if you live near a freeway.

I did this when I moved into my new apartment, making me feel much safer and healthier in my home.

In this article, I’ll explain why you need an air purifier if you live close to the freeway, what kind of model to get, and other tips to lessen pollution exposure when living near the highway.


Why Do I Need an Air Purifier If I Live Close to the Freeway?

Air pollution is everywhere in our modern society.

How technology has advanced and how we fuel most automobiles has filled our air with pollutants. This is also one of the main ways the USA emitted over 67.1 million tons of air pollution in 2021 alone.

This is especially true for people living close to the freeway.

When you live near the freeway, you’re much closer to the source of pollution and the thousands of cars that emit pollutants daily.

So, air pollution has a much easier time making its way into your home, even if you close the windows.

This is why I suggest getting an air purifier if you live near the freeway.

When I moved into my apartment close to the highway, I noticed my allergies were more frequent, and my lungs felt slightly heavier than usual.

But when I got my air purifier, there was a noticeable difference, and I felt much better inside my home.

On top of that, air pollution exposure over a long period dramatically increases your risk of contracting a respiratory disease.

Air purifiers reduce pollution exposure and significantly improve your home’s air quality, which is very important.

What Air Purifier Do I Need If I Live Near the Freeway?

Getting a good model is essential when buying an air purifier for your home or apartment next to the freeway.

Suppose you already have an HVAC system installed. In that case, you can add air purifying filters to your existing system for a more straightforward setup.

When doing this, I suggest you keep an eye out for High-Efficiency Particulate Air filters, also called HEPA filters.

These are the only filters currently capable of filtering out the significant pollutants that float around the air when you live close to the freeway.

With these filters installed in an HVAC system, it’s essential to check on them occasionally, as they are supposed to be replaced after a certain amount of time.

Getting a portable air purifier is another option if you don’t have an HVAC system at home.

But again, when getting one of these air purifiers, you need to make sure to get one with a True HEPA filter.

Otherwise, it may need help to filter out air efficiently, which defeats the purpose of owning an air purifier in the first place.

How to Reduce Pollution Exposure When Living Near a Freeway

While air purifiers significantly reduce pollution exposure when you live close to the freeway, it’s essential to take a multi-faceted approach when protecting yourself against air pollution.

Here are a couple more things you can do when living near a freeway to reduce pollution exposure.

Drive Less

One of the best things you can do to protect your lungs from air pollution is to drive less.

If you live near the freeway, you’ll likely have to drive on the highway when going to your destination.

Even with the windows rolled up, you inhale a lot of pollution when driving on the freeway. That’s why you should consider changing how you get around when living near the freeway.

I recommend taking public transportation or trying alternative methods for commuting, such as cycling, walking, or running.

Avoid Exercising at Rush Hour

Another thing you should do when living close to the freeway is to move your exercise schedule away from rush hour.

There is much more pollution in the air during rush hour, and you need to breathe in more air when exercising.

If you exercise during rush hour, you welcome more pollutants into your lungs, which is the opposite of your goal when living near a freeway.


Do I Need an Air Purifier if I Live Close to the Freeway – FAQs

Do Air Purifiers Help with Freeway Pollution?

Air purifiers are great for freeway pollution. While they won’t do much to the outdoor pollution, they are ideal for removing pollutants from the indoor air if you live near the freeway. So, if you live near the highway, getting an air purifier to protect you against airborne pollutants is a great idea.

How Far Does Pollution From the Highway Reach?

Air pollution can travel large distances depending on wind conditions, weather, and other factors. While you can’t pinpoint the exact distance air pollution from the highway travels, it’s recommended to live at least 500 feet from the freeway and, if possible, stretch that out to 1,000 feet.

Is It OK To Leave an Air Purifier on All Day?

Yes, it’s okay to leave an air purifier on all day. In fact, it’s considered best practice to leave your air purifier on constantly. That way, the device constantly removes pollutants and contaminants from the air, keeping your lungs as safe as possible.

Do I Need an Air Purifier if I Live Close to the Freeway – Final Thoughts

While there are many advantages to living near the freeway, it also means that you’re exposed to more air pollution.

This is why I highly suggest getting an air purifier if you live near the highway.

That way, you’re exposed to much less air pollution at home and protect your lungs long-term.

Can You Recycle Air Purifier Filters: What You Need to Know


Can we really recycle air purifier filters? That would be lovely if we can!

Air, it’s essential for our survival, but just because it’s all around us doesn’t mean it’s always good quality. 

That’s where air purifier filters come in – they help clean the air we breathe by trapping dust, chemicals, and other harmful particles. 

But while air filters are great for keeping us healthy, they can be tough on the environment when not properly disposed of. 

In this post, we’ll let you know if you can recycle air purifier filters, what happens to the filters after they’ve done their job and how you can ensure they’re not harming the planet. 

It’s a serious topic, but let’s have some fun with it, shall we?


Can You Recycle Air Purifier Filters?

You know what’s not so fun? Air pollution

And while air purifiers can help clean the air we breathe, they can also be tough on the environment. 

Running them constantly can use a lot of energy, and those filters must be replaced every few months. So can you recycle air purifier filters?

Unfortunately, you can recycle most air filters because of the toxic particles they’ve collected – they almost usually end up in a landfill. 

Although an air purifier filter might look recyclable, it’s unsafe to recycle because of all the particles. 

Even many recycling centers won’t take them because of the potential health hazards. 

So, the next time you’ve got a bunch of old air filters hanging around your house or office, don’t even think about dumping them in a recycling bin.

But don’t worry; we’ll discuss some ways to ensure those filters don’t harm the planet.

How to Dispose of Air Filters

Air filters are essential for keeping our air clean but are not so great for the environment. 

The vast majority of them contain fiberglass, which can’t be recycled. Even if they don’t, recycling air purifier filters are still unsafe because they’ve been trapping dust, pollutants, and debris. 

So, what do we do? 

The best option is to invest in reusable filters that can be washed and used for years. That way, you can decrease your carbon footprint. 

But if you’re stuck with one-time-use filters, don’t worry; we’ve got some tips on how to get rid of them properly.

Put your used air filter in a large plastic bag

Alright, you’ve got an old air purifier filter you need to dispose of, but you don’t want to just toss it in the trash. 

Here’s what you do: First, grab yourself a plastic bag. Make sure it’s big enough for your specific air filter. 

For example, air purifier filters are usually around 7 to 18 inches on each side, so you’ll need a large plastic bag. 

However, if you’re dealing with a refrigerator filter, it’ll probably fit in the palm of your hand, so a small shopping bag will do the trick. 

Next, ensure no holes are in the bag and open it up nice and wide. Carefully slide that old filter into the bag. And that’s it! 

Tie the bag to keep dust out

So, you’ve safely tucked your old air filter in a plastic bag. 

But we’re not done yet. 

We need to make sure that bag stays closed. 

So, if the bag comes with handles, tie them together and give them a good pull. That should keep the bag closed. 

If you’ve got a lot of extra plastic hanging around the top of the bag, twist it up and tie it into a knot.

That should keep everything nice and secure. 

And if you’re feeling extra cautious, you can always use duct tape to tighten and keep it intact. 

 Put the filter in the trash for pickup

After safely tucking away the old air filter in a plastic bag, it’s time to get rid of it. 

But don’t just leave it in your indoor trash can. 

You don’t want it getting punctured by something sharp and making a mess. 

So, take it to your outdoor trash can, and pop it in there. 

That way, it’ll be picked up with the rest of your garbage when your trash collector comes by. 

If you don’t have an outdoor trash can, no worries. Just keep the filter in your garage.

That’s it! You’ve safely disposed of your old air and done your part to keep the environment clean.


When Should You Discard An Air Purifier Filter?

Cluttering your home with old, broken items can be an energy zapper. 

Even the best air purifiers will eventually show signs of wear and tear. 

And let’s be honest, some of them are pretty big, so getting rid of them can free up some much-needed space. 

This is especially true for necklace units, those air purifiers you put around your neck. 

They’re great for cleaning the air you breathe, but once they’ve run their course, it’s time to say goodbye. 

So, if you’ve got an air purifier that’s not working properly and just taking up space, it might be time to think about getting rid of it.

Replace Dirty Filters with Reusable Filters

Granted, we need air filters to keep the air clean. 

But constantly buying new ones can be a real bummer, especially when we can’t recycle air purifier filters. 

However, here’s the good news: you can reduce the number of filters you use by getting a reusable one! 

That’s right, reusable filters are washable before reinstallation. The cleaning process should occur every few months to ensure it works correctly. 

Plus, they are not only better for the environment, but they’re also made from durable materials that last longer than disposable filters.

Sure, they may be a bit more expensive, but it’s worth it in the long run. 

Plus, you’ll save yourself the hassle of constantly buying new filters. So, reusable filters are the way to go if you want a more eco-friendly and cost-effective option. 

What Can You Do with Old Air Filters?

Air filters are essential in maintaining clean air in your home, but what do you do with them once they reach the end of their lifespan? 

While it’s unsafe to reuse or recycle air purifier filters due to the accumulation of toxins and pollutants, that doesn’t mean you have to throw them away. 

There are many ways to repurpose old air filters for other uses. 

The possibilities are endless, from protecting plants in your garden to making fire starters for camping or using them as oil filters for small engines. 

However, before repurposing an air filter, it is important to consider the possible health hazards and take the appropriate safety precautions. 

  • Use them as plant guards. You can cut old air filters to size and use them as guards to protect your plants from pests and insects. Simply wrap the filter around the base of the plant, securing it in place with a rubber band or twine.
  • Make a fire starter. Roll up old air filters tightly and use them as kindling for your next camping trip or your fireplace at home. They make great fire starters as they easily burn for a long time.
  • Use them as oil filters. Cut the air filter to size and place them in the oil filter housing for small engines or machinery. They will help to filter out impurities and keep the oil clean.
  • Cut them to size and use them to cover furniture or doorways during home renovations to keep dust from spreading to other parts of the house.
  • Use them as a cleaning tool. You can use them to clean blinds, baseboards, or even your car’s dashboard, as they are good at trapping dust and debris.
  • Use them for craft projects to make wreaths, garlands, or wall hangings.
  • Use them for composting: Lay them on the bottom of your compost bin to help filter out debris.

Air filters may have accumulated pollutants and toxins, so make sure you wear gloves and a mask when handling the filters to avoid inhaling or ingesting the particles. 

Also, ensure the filters are completely dry before repurposing them, as moisture can cause mold and mildew to grow.

Recycling Air Purifier Filters FAQs

Are Air Filters Recyclable?

Not all air purifier filters can be recycled. 

While some parts of the filter may be recyclable, the whole thing can rarely be. 

But don’t let that discourage you! 

Look at the instructions that came with your filter and see if there are any recyclable parts you can remove and toss in the recycling bin. 

Every little bit helps!

Why Do I Need to Replace Filters?

You must replace air filters because they get dirty and clogged over time. 

HEPA filters especially need regular replacement to keep them working at their best.

Can I Recycle Dirty Filters Another Way?

You can recycle dirty filters by contacting an HVAC company, using a mail-in recycling service, or investing in reusable filters.

How Do I Order More Replacement Filters?

If you want to stock up on replacement filters, you can easily order them on e-commerce platforms like Amazon. 

But before you hit that “buy” button, double-check to ensure the replacement filter is compatible with your air purifier. 

You want to avoid ending up with a filter that doesn’t fit!
