Why Is My Air Purifier Making A Lot of Noise?

Why Is My Air Purifier Making A Lot of Noise

Most air purifiers today aren’t designed to be 100% quiet.

And if you look at the components of air purifiers, you’ll quickly see why that is.

Most air purifiers feature a fan or a blade, which drives air through the filtration system.

That way, the air in your room gets purified.

For the fan or blade to drive air through the filters, it needs to spin, which produces noise.

And the higher the setting of your air purifier, the faster the fan or blade will spin and the more noise it will make.

While that is common sense, there are times when your air purifier might be making more noise than usual.

If that’s the case with you, in this article, I’ll go over the few reasons your air purifier might be making more noise than normal.

I’ll also detail whether air purifiers are supposed to be loud and what you can do to reduce the noise your unit produces.

Why Is My Air Purifier Producing So Much Noise?

There are several reasons why your air purifier can be loud. And below, I’ll go over some of the most common causes.

You Bought a Loud Model

Did you check your air purifier’s decibel rating before buying it?

I certainly didn’t and had to deal with quite a loud unit for a few years until it was due for a replacement.

While most air purifiers on the market are relatively quiet, some are not.

And having a loud air purifier isn’t ideal if you’re someone like me who can easily get distracted during the day or have trouble falling asleep at night.

Check your unit’s user manual; it should indicate the dBA rating of your air purifier.

If it’s over 60, you’ve just got yourself a loud air purifier without realizing it.

The Fan Speed is High

If you’ve set your air purifier on the highest setting possible, that will cause the fan to spin as fast as possible.

The fastest setting is designed to purify as much air as possible in the shortest amount of time.

If that’s the case, it’s normal for the unit to be much louder than normal.

And since most air purifiers come with several settings, you can simply set your unit to a lower one to reduce its noise.

If you keep your air purifier on 24/7, you can set it to the lowest mode and keep it as quiet as possible.

That way, you’ll get purified air throughout the day and won’t be affected by the fan’s noise.

Damaged, Clogged, or Misplaced Filter

If your filter is damaged, misplaced, or clogged up, there’s a chance that your air purifier can be louder than usual because of that.

So, if you haven’t done any maintenance recently and used your air purifier a lot, you need to take it apart and see what’s wrong.

Even the highest quality filtration system can sustain damage, get misplaced, or get clogged up over time, especially when no regular maintenance is conducted.

How Do I Make My Air Purifier Quieter?

If your air purifier is loud and bothering you, there are many steps you can take to make it quieter.

If I were in your situation, I would:

  • Clean the air purifier as per the suggestions in the user manual
  • Replace the filters if they’re due for replacement
  • Place the air purifier further away from you
  • Put your air purifier on night mode or on the lowest setting

If none of the suggestions above makes your air purifier as quiet as you’d like it to be, chances are that you have a unit that is loud by design.

I would shop around for a quieter air purifier in such a case.

I recommend you check out our guide to air purifier noise levels.

It will help you determine your unit’s decibel rating and what dBA rating air purifier you should look for instead.

Are Air Purifiers Supposed to Be Loud?

Generally speaking, most air purifiers in fine working condition shouldn’t be loud to the point where it’s blatantly obvious.

With that being said, some air purifiers are loud by design.

If that’s the case with your unit, there’s not much you can do but have it on the lowest setting and place it as far away from you as possible.

If you think your unit is getting louder without changing the settings, that can raise some concerns.

If you suspect anything is wrong with the unit, take it apart using the user manual and check for yourself.

If you are not comfortable doing that, take it to a specialist.

And in case your unit is still under guarantee or has insurance, then simply bring it back to the store you bought it from and tell the staff about the noise.

Conclusion

Having a loud air purifier is less than ideal.

An air purifier can be loud for several reasons, including a damaged fan, a clogged filtration system, or you might just have a louder unit.

The air purifier noise reduction steps I shared above should help with the noise.

However, if your unit is loud by design, there’s very little you can do to minimize the noise it produces.

Unfortunately, you’ll have to shop around for an air purifier with a lower dBA rating if that’s the case.

Air Purifier Noise Levels: Guide to Decibel Ratings

Air purifier noise levels

As a sensitive sleeper, one of my top priorities when buying an air purifier was the level of noise it produced.

And since it’s suggested that you leave your air purifier on 24/7, I knew if I bought a loud model, I’d have trouble falling asleep at night.

With that out of the way, I was left wondering how to tell if an air purifier is silent before I buy it.

After some research, I found the answers to all of my questions.

So, in this article, I’ll go over everything you need to know regarding decibels and air purifiers.

Understanding Decibels

Before fully understanding decibels, it’s essential to know the difference between dB and dBA.

Decibels are expressed in dB, and it is a measurement of the sound levels and sound pressure of a particular source.

That said, tons of frequencies are floating around, and the human ear cannot hear all of them.

So, when describing sound levels concerning the human hearing spectrum, the measurements are in A-weighted decibels or dBA.

dBA is the measurement you’ll come across when shopping for an air purifier, so look out for it.

How Do You Measure the Noise Levels of an Air Purifier?

The noise air purifiers produce is measured in decibels or dBA.

Decibels are measured using a decibel meter, specifically designed to count the number of decibels from a particular sound source at a certain distance.

If you want, you can download a decibel tracking app that will tell you the decibel level of your air purifier or one that’s in a store. Here’s an example of the app with my screenshot.

Otherwise, you should be able to just google it.

That way, it’s much easier for humans to gauge which sound levels are tolerable, manageable, or the ones that could potentially be dangerous for your hearing.

Just like you, I never needed to understand decibels before I started looking for a silent air purifier.

So, if you’re unsure what qualifies as a silent air purifier in terms of dBA, keep reading.

What Qualifies as a Silent Air Purifier?

From my personal research, every air purifier brand is slightly different when it comes to noise.

The more expensive models are much better at keeping quiet than their cheaper counterparts.

Despite that, for an air purifier to hit the market, it must undergo some testing.

The manufacturer needs to measure the air purifier’s dBA rating as part of this testing.

This rating represents the noise levels that the air purifier can produce during operation.

Ideally, you want to get an air purifier that produces less than 30 dBA, considered a quiet air purifier. 

Let’s look at some examples to give you a better idea of how quiet 30 dBA is.

As a baseline, let’s imagine you cannot hear any sound from a specific source. This is what 0 dBA feels like.

A whisper would be around 30dBA when right next to your ear.

A typical conversation hovers at around 60 dBA.

With that being said, some air purifiers have different settings.

So, the higher the setting, the louder the unit will be.

When I researched my silent air purifier, I came across models with a dBA rating of just 15.

Benefits of a Silent Air Purifier

There are a ton of benefits to using a silent air purifier.

Below, I’ll share some of the most noticeable ones I’ve experienced.

Better Quality of Sleep

When using a silent air purifier, your sleep quality will improve for multiple reasons.

For one, you won’t have trouble falling or keeping asleep by the constantly running fan of the unit.

And two, the air purifier can be kept during the night, allowing you to breathe clean air.

When we sleep well, we feel good.

And that’s important if we want a happy and productive day ahead.

You Can Leave the Air Purifier On Even When You Sleep

Listening to a humming sound before bed is going to do everything but help you fall asleep.

As a light sleeper, I have to sleep in absolute silence, or else I won’t be able to fall asleep.

However, since buying my super quiet air purifier, I have kept it on around the clock.

Sometimes, I don’t notice the air purifier running in the background.

No Distractions During the Day

As I work from home, keeping my focus and concentration is super important.

But at the same time, I can’t go without an air purifier for allergies due to my sensitivity to them.

They can ruin what would have been a productive day at work.

When I found the air purifier I own now, I was super happy.

It was quiet, to begin with, and had a night mode, which made it even soft.

Now, I can keep my focus and reduce my allergies thanks to breathing in purified and clean air.

Conclusion

Understanding decibel ratings on air purifiers can be pretty complicated, but it’s imperative.

If you’re particularly keen on buying yourself a quiet air purifier, knowing what decibel rating you’re after will be of enormous help.

Ideally, you want a decibel rating below 60 dBA as anything over that is pretty loud.

However, if you’re a person like me who enjoys quiet and peace, then I’d recommend you go for a model that’s 50 dBA or less.

Thankfully, there are a ton of great silent air purifiers on the market, so you’ll have no trouble finding one.

Are In-Duct Air Purifiers Worth It_ (1)

When I first tried to buy an air purifier, I had a choice: get a portable one or an in-duct system.

At first, I was inclined to get a portable option. 

While these wouldn’t be able to clean all the air in my house, they can purify the air one room at a time, which I felt was good enough for my needs.

On top of that, these portable options are generally more affordable than in-duct air purifiers. 

But after some research, I started to see why in-duct air purifiers were generally more expensive than portable air purifiers.

Will An Air Purifier Work Around Walls_ Your Guide to the Right Air Purifier Placement

As much as I understood the benefits of owning and using an air purifier, I wasn’t too keen on placing mine in the middle of the room. 

This is because I pay a lot of attention to the layout and design of my interior spaces. 

Hiding my air purifier near the wall and covered by a small table was a great way to leave my design untouched.

However, when I turned my air purifier on, I barely noticed a difference in the air quality. 

I got an air purifier because I have severe allergies triggered by dust, pollen, and similar pollutants. 

So, when I turned it on and noticed that I was sneezing uncontrollably, I thought I had a faulty air purifier.

This was when I went to the internet to research what was wrong.

The 4 Best Air Purifiers for Pets

The 4 Best Air Purifiers for Pets

I love animals, and despite my allergy to most of them, I own two cats and a small puppy that I recently picked up.

The little suffering they cause me isn’t near as bad as the suffering some people I know go through due to pet allergies.

But still, the allergies are there, and they’re pretty annoying as they reduce the overall quality of time I have with my pets.

And to be honest, that was one of the reasons why I picked up my first ever purifier all those years ago.

Since then, the symptoms of the allergic reactions I have as a result of my pets have minimized. 

I almost don’t even notice them anymore.

But it wasn’t always this way.

I conducted a ton of research when picking up my first air purifier. 

I did this to ensure that it would not only purify the air at my home but also help prevent some of the triggers for the allergic symptoms I get from my pets.

This comprehensive guide will show you four of the best air purifiers for pets.

I will also include the one I use right now and the one I used a few years ago.

And at the end of the guide, I’ll show you how air purifiers help with pet allergies and share a few tips to help you when shopping for your next air purifier for pets.

Coway Airmega AP-1512HH(W) – The Best Overall Air Purifier With Pets

The Airmega AP-1512HH by Coway is arguably my favorite air purifier for pets on the market – hence why it is on top of the list.

When I first came across this unit, I bought it within 2 weeks.

It just made sense because I knew the difference it would make in my overall quality of life around my furry friends.

This air purifier has a four-stage filtration system – the last of which is an ionizer, which I wish wasn’t included.

As you may already know, I don’t recommend anyone to get an air purifier with an ionizer as it can do more harm than good.

Thankfully, you could turn the ionizer off on this model greatly relieved me.

That said, the filtration system without the ionizer is one of the best on the market.

This is because it has a pre-filter, carbon filter, and HEPA filter. 

These are some of the components you need from an air purifier if you’re looking to handle pet allergies.

On top of that, this is a very quiet air purifier.

This means your pet won’t be bothered by the noise and won’t have to turn the air purifier off while you sleep.

The air purifier even has an air quality monitor that you can use to check the air quality in your room at any given moment.

The machine also adjusts its settings automatically based on the air quality, which adds an extra layer of convenience.

Aside from the ionizer, which you can turn off anyways, I didn’t find too many things wrong with this air purifier.

It remains my favorite pick on the market. I would gladly recommend this to any pet owner who wants an air purifier to handle their allergies.

Pros:

  • Easy to use
  • Sleek and modern design
  • A great 4-stage filtration system
  • Silent operation
  • Automatic mode

Cons:

  • Comes with an ionizer (which you can turn off)

If you’re shopping for an air purifier for pets on a budget, 

I couldn’t recommend the Levoit Core 300 enough.

To this day, this air purifier quickly falls in the top 3 because of how awesome it is in terms of performance, design, and value for money.

It was one of my first ever air purifiers, and I have it stored away in my home.

This air purifier comes with a three-stage HEPA filtration system, perfect for tackling your pets’ allergy triggers.

With that being said, it is pretty tiny.

It can cover an area of 219 ft² / 20 m², making it perfect for an average-sized room.

The filtration system within this unit is so great that it can capture and keep hold of 99.97% of solid particles of size as little as 0.3 microns.

In terms of size, it measures 8.7 x 8.7 x 14.2 in / 22 x 22 x 36 cm and weighs just 7.5 lb / 3.4 kg.

The only real downside to this air purifier is that it doesn’t have an activated carbon filter.

This means that it won’t be able to help you with VOCs and cooking odor, and other gasses.

Pros:

  • One of the most affordable air purifiers on the market
  • Easy to use
  • You can change the filters depending on your needs
  • Silent
  • Great for small spaces

Cons:

  • Not ideal for larger spaces
  • Can’t clean the air from smelly gasses

Bissell air400 – The Best Silent Air Purifier for Pets

Silent operation is essential if you’re looking for an air purifier for pets.

If you want to effectively handle pet allergies with your air purifier, keep it on as much as possible.

In fact, it’s best practice to leave your air purifier on 24/7.

When you have a silent air purifier, it’s much easier to always leave it on.

This is because you won’t have to worry about the noise that keeps you up at night or annoys you throughout the day.

And when it comes to silent operation, this air purifier is arguably the best on the market.

On top of that, it comes with an excellent filtration system.

It can handle pet dander and other allergens like dust and pollen.

This air purifier even comes with a carbon filter that you can use to absorb VOCs and other toxic gasses that may be floating around the indoor air.

If there’s one downside to this air purifier, it’s on the expensive side.

This isn’t too much of a worry if you’re looking to invest money in a quality unit since it has many features to justify the price.

Considering the features, it isn’t too far off to say that this air purifier is a bargain.

Additionally, it has an automatic system. So, all you have to do when you get this air purifier is plug it in and leave it that way.

You won’t have to worry about adjusting the air purifier and its settings throughout the day.

Pros:

  • Great automatic system
  • Very silent operation
  • Ideal for medium and large rooms
  • Multi-stage filtration
  • Low-key design

Cons:

  • Relatively expensive

Coway Airmega 400(G) Smart Air Purifier – The Best Premium Air Purifier for Pets

Last on this list is the best premium pick on the market.

I loved everything about this air purifier. 

It even came with a few features that beat out the Coway model that I went for 6 months ago.

However, it didn’t rank as the top pick on the list because it’s pretty expensive.

Since it’s expensive, you can expect this unit to have many great features.

It has a modern design doesn’t steal too much attention without looking bland. 

Another cool feature is that the air purifier runs on a smart system. This means you won’t have to worry about adjusting the settings manually.

All you have to do is turn it on and feel the results.

This air purifier is also great for large spaces.

It is designed to work in rooms of up to 1,500 square feet, which is why it’s so expensive.

On top of that, it comes with a filtration system that can easily filter out pollutants and pet dander in sizes as small as 0.3 microns.

Aside from the price, I don’t have that many complaints about this model.

However, remember that larger air purifiers inherently generate more noise.

While the noise isn’t unbearable, it is slightly louder than the noise on other purifiers for smaller spaces – such as the models listed above.

Pros:

  • Great for large spaces
  • Great filtration system
  • Automatic air quality monitor
  • Premium design

Cons:

  • Fairly expensive
  • A bit noisier than smaller models

How Do Air Purifiers Reduce Pet Allergies?

It may seem weird that an appliance like an air purifier can reduce pet-related allergies.

However, this is actually one of the primary reasons many people with pets get air purifiers in the first place.

To understand how these devices reduce pet allergies, we must look at how they work.

While they may seem fancy and intricate, air purifiers are simple machines.

Without the bells and whistles, an air purifier is essentially a fan, motor, and filtration system inside a case.

All the air purifier does is push air through the filter so that the filtration system can trap the different particles and contaminants in the air.

That way, clean air exits the air purifier and enters the room, ready for us to breathe.

So, how does the filtration system actually work?

Let’s start with the pre-filter.

This is for the larger particles in the air, like hair, dirt, and fur.

However, these aren’t intricate filters and are usually made of cloth, so a fair amount of particles slip through.

From the pre-filter, the air passes through the carbon filter.

This filter is there to absorb toxins and gases in the air that may cause you respiratory issues.

For example, it can capture VOCs or volatile organic compounds that can do plenty of harm if you’re exposed to them over time.

It can also absorb the compounds that cause strong odors, which makes it great for pet owners.

The last filter is the one that does the most for pet allergies.

This is the HEPA filter.

These ultra-fine fiberglass mesh filters are designed to capture particles as small as 0.3 microns.

These include dust, pollen, and pet dander, which causes allergies in the first place.

Tips When Buying an Air Purifier for Pets

When buying an air purifier, you can’t just get any model you find online and expect it to work.

As I mentioned, different air purifiers have their own functions, and not all are designed to help with pet allergies.

In this guide, I chose to highlight four of the best air purifiers for pets.

While others can help with pet allergies, the ones I mentioned above were the most effective at the job.

To find these air purifiers, I had to look at specific features.

And while any of these air purifiers will do a great job if you’re looking to reduce your allergic reactions, you still need to find the right one for your needs.

So, let’s look at some of the significant considerations you need to consider when buying an air purifier for pets.

That way, you can easily choose the one from this list that best suits your needs.

Get the Right Size

Firstly, you need to consider the size of the air purifier.

As you can see on the product descriptions and the packaging, air purifiers are made to handle specific room sizes.

So, if you’re buying an air purifier for your home, try and measure the space you want to purify and find air purifiers that can handle it.

The thing is, you won’t be able to use one air purifier for the entire house.

So, you will have to move the air purifier from room to room, depending on where you or your pet are at the time.

That’s why you should measure the biggest space in your house.

Only Get High-Quality Filters

Another thing you need to consider is the filtration system.

To effectively handle pet fur and dander, you want to get the best filters possible.

Ideally, get an air purifier with a multi-stage filtration system.

The best filtration systems include a HEPA, carbon, and pre-filter.

You need to look for this in any air purifier, especially when buying one to handle pet fur and dander.

That’s why air purifiers without HEPA filters are not worth it if they aim to reduce allergies.

One type of purification method I highly suggest you avoid is ionization.

This is the process of introducing negative ions into the air, which will bind with the particles in the air and cause them to fall to the ground.

This isn’t ideal as you still have to sweep the dust eventually.

The Quieter, the Better

The last thing I recommend when buying an air purifier for pets is to look for silent models.

Pets have sensitive ears, and some of the sounds that aren’t a problem for us can cause a lot of stress for our pets.

So, I highly recommend finding silent air purifiers that won’t constantly stress out your pet.

On top of that, you want to keep your air purifier on 24/7, which can be problematic if your air purifier is loud, especially when sleeping.

Luckily, most air purifiers nowadays are pretty silent. That said, there are still models on the market that are quieter than others.

Conclusion

If you have pet allergies, it can be hard to be around animals, no matter how much you love them.

But nowadays, there is a way to live harmoniously with your pet, even if you have pet allergies.

And that’s with an air purifier.

Not all air purifiers will be effective at reducing pet allergies, but there are a fair amount that will.

And in this list, I chose to highlight some of the best options available that can effectively reduce the pet dander and allergic reactions accompanying owning a pet.

So, if you have pet allergies, any one of the air purifiers I suggested above will be great for you.

How Often Should You Replace The HEPA Filter?

When Should I Replace My HEPA Filter

As awesome as owning an air purifier is, you can’t just buy it, use it, and forget about it.

Like all appliances in the average modern-day household, air purifiers must be regularly maintained to operate at their best and serve their purpose for as long as possible.

When I bought my first HEPA filter air purifier, I had no idea it needed maintenance.

This meant any kind of cleaning or even replacing the filter itself.

Thankfully, a friend told me about it a few months into using it and that the HEPA filter needs to be replaced regularly.

I don’t even want to imagine what would have happened if I had never found out about this.

Because of my personal experience, I know that many air purifier owners also don’t know that their units must be maintained.

It needs to be cleaned, and the filter replaced to get the most out of it.

So, in today’s article, I will tell you everything you need to know about replacing your HEPA filter.

I will talk about when you need to do it, how to tell if it needs changing, how to do it, and more.

What is a HEPA Filter?

Before I tell you how often you should replace your HEPA filter, let’s start from the beginning.

That way, it will make sense when I tell you the answer.

HEPA filters are a specific type of high-quality air filtration filters that meet the HEPA filter standard.

For a HEPA filter to qualify to meet industry standards, it must be able to remove at least 99.97% of all solid particles in the air, including those as little as 0.3 microns in size.

Due to their extreme effectiveness in capturing solid particles from the air, they are the most popular type of filtration system in most modern-day air purifiers.

How Do HEPA Filters Work in Air Purifiers?

Before I get into how HEPA filters work, it’s first essential to understand how the air purifier works.

When you turn on your air purifier, the motor will start to spin the fan inside the air purifier.

This fan will then suck in air from your room, drive it through the HEPA filtration system, and release it back into your room.

Important to note that when air goes through the filtration system, 99.97% of the solid particles get stuck inside the unit, thanks to the HEPA filter.

As a result, all the air released back into the room is purified.

As for how the HEPA filter works, it doesn’t actually do anything.

It relies on the fan to drive air through it, and as I mentioned above, the solid particles get left behind during that process.

Why Does a HEPA Filter Need Changing?

Now that you know what a HEPA filter is and how it works, it’s pretty obvious why you need to change the filter regularly.

For more clarity, when the HEPA filter captures pollen, dust, hair, and other particles that are floating in the air over time, the HEPA filter will start to clog up.

This is when you need to clean your air purifier and make its life easier so it can serve you for longer.

When you regularly clean your HEPA filter, you will increase its life span, so you’ll have to replace it less often.

However, that doesn’t mean you don’t need to change it every once.

The ultra-thin fibers the HEPA filter is made of will get worn down and damaged over time.

As a result, the HEPA filter will become less effective than it once was.

Now, note that your air purifier will most likely still work as usual, except that it won’t be purifying the air as well as it once did.

If you don’t replace the filters or clean your air purifier often, it will damage the device or, worse, not turn on.

How Often Should You Change the HEPA Filter of Your Air Purifier?

I personally change the HEPA filter in my air purifier every 12 months.

That being said, I use my air purifier all the time.

It literally runs 24/7 as I enjoy breathing in clean air while I work from home and sleep during the night.

On top of that, I actively clean it, which prolongs its effectiveness.

I am fully aware that this isn’t the case for most people.

So how often you replace your HEPA filter depends on the maintenance level you conduct and how often you use your unit.

As a general rule of thumb, you should start thinking about replacing your HEPA filter after 8,000 hours.

Tracking the hours can be tricky, so the general advice if you use your air purifier daily is to change the HEPA filter every 12 to 18 months.

This is for the standard, non-washable HEPA filter.

Suppose you happen to have an air purifier with a washable HEPA filter.

In that case, you can easily use that filter for several years without worrying about replacing it.

That said, when I was in India, I bought the best air purifier for Delhi.

The air quality is some of the worst in the world, and over the 2 years I lived there, I had to change my washable HEPA filter 3 times.

How to Tell if Your HEPA Filter is Due For a Replacement?

You probably won’t be able to tell if the HEPA needs a replacement, even if you took the air purifier apart yourself.

Unless the HEPA filter is severely damaged, the naked eye can’t tell the difference between the quality of the fibers of a new and a used HEPA filter.

To tell if your HEPA filter is due for a replacement, I advise that you use a PM2.5 air quality monitor, which is also known as a particulate counter.

This device will be able to measure the quality of the air inside your home.

The best way to tell if your HEPA filter needs replacing is by measuring the air quality at different periods.

If you’re reading this and haven’t bought an air purifier, you can measure when you first get your air purifier vs. a couple of weeks later.

Or, if you already own a purifier, you can measure now and then a couple weeks from now.

That will give you a good indication of whether or not it’s time to get a new filter.

Some more complex and likely expensive air purifiers have quality control sensors.

So when your HEPA filter is due for a replacement, the air purifier will let you know.

How Do You Replace a HEPA Filter?

Unless you own a high-end model that can only be maintained by a professional, changing the HEPA filter inside your air purifier is simple.

Next, I’ll show you all the steps you should take to change the HEPA filter in your unit so you can continue reaping the benefits of your air purifier.

Get the Right Protective Gear

Before you do anything, you must ensure you have all the proper protective gear.

I recommend getting gloves (any type would work), protective goggles, and a mask.

This way, you will prevent any of the dust, hair, pollen, and mites from getting on your skin, in your eyes, or even being inhaled accidentally.

I never took these protective measures when I changed the first HEPA filter. 

And I accidentally dropped the HEPA filter on the floor.

I can’t tell you how much of the dust on the filter flew into the air and ended up in my lungs.

Take the Air Purifier Apart

I can’t exactly tell you how to take your air purifier apart since we all have different units built differently.

The best tip I can give you is to watch a YouTube video or follow the user manual that came with your air purifier when you bought it.

Most air purifiers are pretty simple in nature, so taking them apart takes a few minutes.

I currently own the Levoit Core 300, and to reach the HEPA filter, I flip it over, take off the bottom cover, and the HEPA filter is right there.

If you own a more complex unit, I would advise that you record yourself taking it apart.

That way, when the time comes to put back the air purifier, you can use the video if you get stuck.

I want to stress that your air purifier must be plugged off the wall before you start to take it apart.

Take the HEPA Filter Out and Replace It With the New One

Once you reach the HEPA filter inside your unit, pop the new one in.

The HEPA filters in most air purifiers are easy to put into place.

My HEPA filter clicks into place, and that’s how I know it’s installed correctly.

Some advanced air purifiers may have sensors that detect 

Put the Air Purifier Together

Once you’ve placed the new HEPA filter, it’s time to put everything back together.

Remember to use the user manual at all times, as that will help you take the unit apart and put it back together.

If you get stuck, refer to the recorded video of yourself taking the air purifier apart.

Conclusion

Depending on usage, you should ideally replace your HEPA filter every 12-18 months.

If you use your air purifier in a heavily polluted area around the clock, as I did, then replace your air purifier every 6 to 12 months.

As a general rule of thumb, you should change the HEPA filter in your unit after 8,000 hours of usage.

And remember, if you have a washable filter and take proper care of it, that can prolong its usefulness and result in you having to change it less frequently.

What Does A Red Light Mean On And Air Purifier

When I got my first air purifier, I was excited about how effectively it cleaned the air in my home. 

However, I noticed a blinking red light on my device a few weeks after using my air purifier.

I was worried because the air purifier was working so well at that point, and there was a considerable reduction in allergies and foul odors at home.

If the red light meant that my air purifier was broken, I would have been quite disappointed and frustrated.

So, I went to the internet to look for help and was happy to discover that there’s a good chance that my air purifier isn’t broken.

However, figuring out what the blinking red light on my air purifier meant wasn’t easy.

Can I Move An Air Purifier From Room to Room?

I know many people who buy a portable air purifier and leave it in one room in their apartment. 

And when I tell them that it might be best to move the air purifier around from time to time, they often tell me they never knew that you could move an air purifier from room to room.

But looking back, I had no idea how to use my first air purifier either. 

I understood its benefits and knew why I needed one, but knowing how to use one effectively is a different story.

So, if you’re wondering if you can move an air purifier from room to room, you aren’t alone.
