If you’ve been looking for an air purifier recently, you might have encountered one with an activated carbon filter.
With so many filtration systems to choose from, I wouldn’t expect you to know what a carbon filter does because I didn’t.
When I first shopped for my air purifier, I had to Google every phrase and term to find out what my unit could do for me.
So, if you’re wondering what a carbon filter can do for you, you’re in the right place.
In this article, I will go over everything you need to know about carbon filters and what they can do for indoor air quality.
But before I get into what carbon filters do, it’s essential to understand what they are and what they’re made of.
Activated carbon filters are essentially carbon broken down into tiny carbon particles.
When it comes to air purifiers, you’ll typically see them in granular or even a powdered block form.
Before they are ready for use, the carbon is treated to be highly porous.
The more porous the carbon is, the better it will capture all the particles and contaminants in the air.
From my experience, the large majority of carbon filters are treated to be highly effective at capturing particles.
My personal air purifier’s carbon filter is fantastic at purifying the air, and it’s not even the most expensive one.
Unlike HEPA filters, which can capture solid particles such as pet dander, pollen, and dust, carbon filters can’t do that.
Carbon filters are designed to deal with gasses and non-solid particles in the air.
These include anything from pet and cooking odor to VOCs and smoke from a fire or cigarettes.
Unlike HEPA filters, which trap solid particles, carbon-activated filters absorb them.
The absorption process happens when an organic compound chemically reacts with the activated carbon.
When that happens, the organic compound will stick to the filter while all clean air passes through.
So, if you are dealing with unpleasant smells daily, an air purifier with a carbon filter can help.
I live in a bustling city, and the smell of pollution is pretty terrible.
Since I bought my air purifier with a carbon-activated filter, everything changed for me, and I couldn’t recommend them enough.
Now that you know what a carbon filter does, let’s look at how it works.
It doesn’t sound straightforward when you hear that your carbon filtration system must have a chemical reaction to work correctly.
However, that’s not the case at all.
The process is straightforward.
The carbon is sold in thick or thin packets, so you won’t get a pile of carbon you need to deal with on your own.
These packets are designed perfectly for your air purifier.
They can often just be inserted into the unit in 2 minutes and left to do their job.
When you turn your air purifier on, air will flow into the unit’s purification system.
As the contaminated air enters the system, it will pass through the active carbon.
Then, the contaminated air will be absorbed while the rest of the purified air will pass through.
That’s the whole deal around carbon filters.
They’re straightforward in nature but are super effective at doing their job.
Like HEPA filters, carbon filters also come with many benefits you will experience from day one.
Below, I’ll go over the most notable benefits I’ve experienced from using a unit with a carbon filter for the last five years.
One of the most significant benefits of a carbon-activated filter is that I can breathe in odorless air inside my home around the clock.
This is a big deal for me because I live in the center of one of the biggest cities in the country.
When I go outdoors, I can smell the pollution from the traffic, the odors lingering in the air from local restaurants, and more.
All those smells would be in my home had I not used an air purifier with a carbon-activated filter.
I have asthma and suffer from seasonal allergies a lot.
Since purchasing my air purifier with a carbon filter, my asthma attacks have reduced significantly.
This is because all of the triggers for my asthma are stuck or absorbed by my air purifier.
If you have asthma, COPD, or any other respiratory condition, a carbon filter will help you immensely.
We’ve all heard the saying that you are what you eat.
How you feel isn’t only related to the quality of food and air you eat.
Since buying my air purifier with a carbon filter, my sleep quality has improved tremendously.
I no longer wake up tired, exhausted, or dreading to start the day.
Breathing in higher-quality air was life-changing, and I couldn’t live without my unit again.
Though all activated carbon filters are great at removing non-solid odors from the air, there are a few different types.
For example, some carbon filters contain more carbon than others.
Naturally, those with more activated carbon will do a better job purifying the air and last longer.
Aside from that, you also want to pay attention to the size of the carbon.
This is because smaller carbons tend to yield faster absorption rates.
For example, the Blueair air purifiers feature one of the best and most advanced carbon filtration systems.
Their carbon filters are infused with additional compounds such as copper oxide and magnesium dioxide.
This helps the air purifier deal more effectively with hazardous pollutants such as carbon monoxide, ozone, and ethylene oxide.
So, before you jump on the first air purifier with a carbon-activated filter, check out all those small details as they matter.
To make the most out of your carbon filter, ensure you install it properly and replace it often.
The more you use the air purifier, the more often you’ll need to replace the carbon filter.
That way, it will always purify contaminated air before it enters your lungs.
Aside from that, I recommend buying an air purifier with a multi-stage filtration system.
That way, your unit will have carbon and a HEPA filter simultaneously.
This way, the unit will effectively cleanse the air of both solid and gaseous particles.
The result will be healthy and purified indoor air from all possible hazardous particles you could inhale.
Air purifiers with multi-stage filtration systems are more expensive than HEPA filters.
If you’re considering buying a unit with a carbon-activated filter, know that it will likely cost you a little bit more.
If your budget allows it, the next thing you need to consider is your needs.
Are any odors inside your home bothering you that you want to eliminate?
If so, you should get an air purifier with a carbon-activated filter.
Suppose you don’t particularly care about cooking odor or smells coming from the outside in your home. In that case, a carbon filter isn’t worth it.
That said, carbon-activated filters don’t just eliminate bad smells you don’t like.
They also eliminate harmful gas particles in the air, such as VOCs, smoke from a fire, and others.
So even if you don’t care about cooking odor, having a carbon-activated filter at home can benefit your overall health.
Using a carbon filtration system indoors is entirely safe.
I’ve been using one for the better part of 5 years, which has been life-changing since I live in a very polluted country.
However, I came across a few reports of people saying the carbon filters in their units have been re-releasing the odors they initially captured.
This only happens if the carbon filter is old and the carbon has been used up.
I have never experienced this issue because I change my carbon filters per the suggestions of the user manual of my air purifier.
So, make sure to change your carbon filter periodically to avoid this from happening to you too.
I change mine every 8-12 months and use my air purifier 24/7.
Changing your carbon filter every 12-16 months will likely be fine if you use your air purifier less frequently.
Do read your particular air purifier user manual to be sure.
Carbon filters are an excellent way to purify the air from all the gas particles indoors.
A carbon filter will come in handy to eliminate cooking odors, pet-related smells, smoke from a fire, or nasty and lingering cigarette odors.
Granted, air purifiers with a multi-stage filtration system that includes a carbon filter can be expensive.
However, I can vouch for them and say they are worth the money, especially if you want a fresh-smelling home.
Buying an air purifier outright isn’t something most people are comfortable with.
This is especially the case if they’re going for a more premium model that costs a good chunk of money.
When I first bought my premium air purifier, it cost around $500, and at the time, I wasn’t in a position to pay for it in full on the spot.
So, I explored a range of air purifier payment plans and went for the best one that I could find at the time.Read more
There are many air purifiers available.
And one specific air purifier that’s been causing a lot of controversies is the ionizer air purifier.
When I bought my first air purifier, almost all of the guides and forums I read advised against getting an ionizer air purifier.
But what are these air purifiers, and why are they so controversial?
I’ll explain all of that and more in this article.Read more
Modern-day air purifiers come with a ton of convenient features.
When I bought my first air purifier, I was overwhelmed with what was possible.
Granted, cheaper and more basic air purifiers don’t have as many features and functionalities, but most air purifiers do.
And one of the features that I was pleasantly surprised with was the timer.
When you have a timer on your air purifier, you won’t have to go to it to turn it off and on.
All you have to do is set the timer yourself, and the air purifier will turn on automatically at a set hour of the day.
For instance, if you’re heading to bed at 10 and want the unit to start working at 9:30, you can set it to do that.
There are more than a handful of air purifiers on the market with built-in timers, and in this article, I’ll share some of my favorite models.
There are more than enough air purifiers with built-in timers, but not all of them are worth it.
After extensive research, I believe the three models below are worth the most within their respective price ranges.
In my opinion, the best air purifier with a timer is the Honeywell HPA300.
One of the reasons why this particular air purifier is my favorite is because of its air purification capacity.
This air purifier is well-equipped for large rooms up to 465 square feet, which is more than enough to handle any house area.
On top of that, it has a tremendous multi-stage filtration system.
The air purifier has a true HEPA filter, essential for removing solid particles such as dirt, dust, pollen, and others.
On top of that, it has a pre-filter for larger particles like pet dander and a carbon filter for nasty or harmful smells and odors.
In other words, it is the all-in-one solution for your air purification needs.
And, of course, this model has an excellent timer feature.
This air purifier has three different timer settings: a 2-hour, 4-hour, and 8-hour timer.
You won’t have to worry about turning the air purifier off again.
All you have to set the timer and leave it to do its job.
Once it hits the set time, the air purifier will automatically shut off, which is extremely handy.
In terms of design, this air purifier certainly isn’t lacking.
The sleek black colorway can fit in very well in many homes and doesn’t steal that much attention.
As I personally own this air purifier, after a few months of usage, I have zero complaints about it.
It would have been great if this air purifier was a bit more affordable, but it’s still very worth the price.
So, aside from a slightly higher price tag, this air purifier with a built-in timer is a great and worthwhile purchase.
When I initially went to buy an air purifier, I assumed you would have to spend upwards of $250 for a good model.
However, this InvisiClean air purifier proves that you don’t need to bust the bank to get your hands on a high-quality air purifier.
This model comes with tons of great features that exceed its price range.
However, as you would expect, my favorite feature is the combo of a HEPA and a carbon-activated filter.
It’s hard to find an air purifier at this price with a true HEPA filter, let alone one with a multi-stage filtration system.
On top of that, it can handle spaces up to 1,270 square feet, which is far more than any other option on this list.
This unit is an excellent choice if you’re looking for an air purifier for a larger basement, office space, or hall.
This air purifier also uses UV-light technology to further clean the air.
This is a unique feature as not many portable air purifiers like this utilize UV light, so it’s a welcome change.
That said, the one complaint I have with this air purifier was the ionizer.
Ionizers aren’t that bad, and they can actually be very effective at clearing the air of dust and other solid particles by causing the particles to fall to the ground.
However, I have two issues with this technology.
Number one, ionizers produce ozone.
The air will smell like ozone, which can be dangerous if you breathe in too much, so I don’t recommend using this feature too often.
On top of that, since the particles fall to the ground, you still have to sweep or vacuum them, which defeats the purpose of owning an air purifier.
Besides the ionizer, this air purifier is one of the best budget options for an air purifier with a timer.
While you don’t have to spend too much money to get your hands on a good air purifier, there are specific models on the market that are worth the money.
This Medify MA-40 air purifier is one of them.
If you want an air purifier with a timer that comes with premium features and will last a long time, this is the one for you.
To start, let’s look at the design.
Out of all the models I chose on this list, this one has the most unique and modern design, which is one of the key reasons I chose it as the premium pick.
On top of that, this air purifier has a true HEPA filter and carbon filter.
So, if you’re worried about VOCs, smoke, solid particles like dust, pollen, and others circulating indoors, don’t.
This air purifier is capable of taking care of solid and gaseous particles.
The Medify MA-40 also has a tremendous built-in timer, which can be set between 0 and 8 hours.
This gives you way more flexibility than any other air purifier on this list.
It’s also very quiet, so you won’t have to worry about loud noises distracting or keeping you awake at night.
And since this is a pretty air purifier, you can expect it to come with great premium features.
For example, this air purifier can handle spaces up to 1,600 square feet, which is a lot and probably excessive for most people.
It also has a touch-screen display, which is a neat and modern feature to have.
In fact, my only real complaint about this model is the price.
It’s the most expensive model on this list, and it was a bit out of my price range when I was shopping for an air purifier.
However, if I had the money, I would have gone for this one over the Honeywell model I own.

For some people, a timer might seem an excessive feature and a waste of money.
So, why would anyone want an air purifier with a built-in timer in the first place?
Well, that’s because air purifiers with timers allow you to use the air purifier in ways that best suit your needs.
For example, if you know you return from work at 5 PM daily, you can set your air purifier to turn on at 4 PM.
That way, the air purifier has 60 minutes to purify the air in your room before you return home.
This means that as soon as you’re home, you can start breathing in clean and purified air as the unit has already been working for an hour.
I personally find this feature super handy.
I mostly use the timer to set my air purifier to turn on for about 20-30 minutes before I head to bed.
Having a built-in timer in your air purifier is excellent.
Still, it’s not the only handy feature air purifiers tend to have.
Here are a couple more important features to remember when buying an air purifier.
One of the essential features you want to consider in an air purifier is the noise levels it produces when purifying the air inside your home.
The last thing you want to do is get a loud air purifier.
Trust me, having a humming noise in the background all the time can be very annoying and could even put you off from using the air purifier 24/7.
I’d recommend you go for an air purifier that produces a maximum dB (decibels) of 50-60.
Anything over 60 dB is way too loud. It will be very noticeable, especially if you use the unit in a small room.
The units I’ve recommended above are very quiet, so you have nothing to worry about.
However, if you plan on shopping for an air purifier or doing more research, read my air purifier noise levels guide.
That way, you can understand decibel and air purifiers and what is considered a good choice and what isn’t.
An air purifier without a good filtration system isn’t worth it.
If you really want to improve the air quality inside your home, buying an air purifier with a sound filtration system is non-negotiable.
If you’re on a budget, I’d recommend a two to three-stage filtration system, and if you have a bit more money to spend, a 4-stage filtration system would be ideal.
The typical 3-stage filtration system is a standard, though.
It features a pre-filter, a HEPA filter, and a carbon-activated filter.
This combination of filters can effectively remove solid and gaseous particles in the air.
From dust and pet dander to VOCs and harmful smoke, an air purifier with such a filtration system will have no trouble dealing with all such particles.
If you want to go all out when buying an air purifier, consider getting one with an automatic mode and many smart features.
These are entirely optional but can be pretty nice to have as they will make using your air purifier much easier and more convenient.
An air purifier with an automatic feature can adjust the unit’s performance based on the quality of air or your own presets.
If you’ve never owned an air purifier, you might be a bit skeptical of why you should buy one in the first place.
In this section, I’ll outline some of the most significant benefits of using an air purifier.
The first and most obvious benefit is that the air quality inside your home will be dramatically better than outside.
This is because most modern air purifiers feature advanced filtration systems designed to capture up to 99.97% of all solid particles in the air.
Any models I recommend will also take care of VOCs, cooking odors, and other nasty or harmful smells and glasses.
So, if you want to enjoy and breathe clean and purified air, having an air purifier is the best way to do that, especially if you live in a polluted city.
I personally suffer from allergies a lot during the allergy season.
And before I had my first air purifier, I used to have a pretty terrible time.
However, shortly after using it, my allergies completely disappeared when I was inside my home.
And it makes sense.
A purifier with a true HEPA filter can capture all solid pollutants and allergens that irritate your lungs before you breathe them in.
So, if you’re suffering from allergies, getting an air purifier that can tackle allergies is a fantastic investment that I couldn’t recommend enough.
Sleep is critical.
Poor sleep causes mood swings, feelings of tiredness, and fatigue.
It can even go as far as impacting your focus and productivity.
When I lived in India, the air quality was the worst I had ever tried, and it affected my sleep to the point where I could hardly fall asleep.
Thankfully, I bought the best air purifier for Delhi, quickly resolving my problems.
Even if you don’t believe the quality of air affects your sleep until you get to sleep in a room with purified air, you won’t honestly know.
Having an air purifier with a built-in timer can come in very handy.
You can simply set the time for the air purifier.
Once the right time comes, the air purifier will automatically turn on and start purifying the air.
This is great if you plan on leaving your home for a while or being busy with other activities.
Fortunately, my list of recommendations features the three best air purifiers across three different price ranges.
And honestly, no matter which unit you go for, you can’t go wrong.
When you’re pregnant, you’re told you must put aside the smoking, alcohol, junk food, and other unhealthy habits you might have.
And while that’s true and every pregnant person should do it, you’re not told that you also need to breathe in clean air as much as possible.
If what you consume can impact your soon-to-be-born baby, so can the quality of the air you’re breathing.
I remember when my wife was pregnant with our son just last year.
I had done some research and came across the importance of owning an air purifier for pregnancy.Read more
When I decided to put the time and effort into my basement renovation project, I knew air quality would be a significant concern for me.
My basement has always been super dusty, and the air quality has never been good enough for me to spend a good chunk of time there.
And since I have an air purifier for my room, I knew the only viable solution to my problem was to get an air purifier for my basement.
If you’re in a similar situation and are looking for an air purifier for your large basement but don’t know what model to get, I’ve got you covered.
When I bought my basement air purifier 4 months ago, I did a ton of research on the topic.
And in this article, I’ll share with you my favorite air purifiers for large basements on the market today.
But before I do that, I want to go over some of the core reasons why getting an air purifier for your basement is a good idea.
If you get a pen and paper and start listing all the reasons you need an air purifier for your basement, you can keep going for a while.
For me personally, there are three reasons why I bought mine, which most definitely applies to you too.
By default, basements are always super dusty, and air quality is generally very poor.
And while this is all thanks to poor ventilation, the lack of regular cleaning, and a few other reasons, there’s not much you can do about it.
And yes, you can always install a proper floor, hoover all the time, and install a ventilation system; that will cost you a fortune to do.
However, thanks to an air purifier, you can quickly make the air inside your basement free of dust flying in the air within hours.
Over the years, there’s a high chance that your basement has developed its own unique odor without an apparent source.
That can make the eradication of the odor a challenging task.
But with the right purifier, you can quickly clear up any unpleasant odors, even if there’s no apparent source that they’re coming from.
To do that, you need an air purifier with an activated carbon filter. These filters are specially designed to eliminate the odors present in the air.
While such a filter won’t give a lovely scent to the smell of the air, it will make it neutral, which is what we all want anyway.
The basement is usually the go-to option whenever you build or create a hang-out space at home.
People barely use this space in the house aside for storage, which means that you can quickly clear it out and transform the space into anything you want.
The basement could become a games room, exercise room, or a space to have a couple of drinks with friends.
However, without clean air present in the basement, you can only stay down there for so long before you want to head back up to get fresh air.
When you get a versatile air purifier and have access to purified air, the basement can quickly become an enjoyable place to spend a good few hours.
When looking for my own air purifier for my basement, I did a ton of research.
And in the section below, I’ll go over three of my favorite air purifiers for large basements.
To start, I want to highlight my favorite option on the market, which is also the model I use in my basement, the InvisiClean Aura II.
The first reason I chose this air purifier was pure because of its air purification capacity.
Like most of you reading this article, I have a fairly large basement, so I need a powerful air purifier to clean the air within my ample space.
This InvisiClean model can handle areas up to 1,276 square feet, which is more than enough for most large basements.
Another excellent feature I liked in this model is its advanced filtration system.
This model features an H13 HEPA filter, an activated carbon filter, an ionizer, and UV-C light.
It quite literally has everything you could possibly need from an air purifier.
This unit can remove not only 99.97% of all solid particles as small as 0.3 microns but also remove odors, gasses, and VOCs in the air.
One downside to this unit is the ionizer, which I never recommend.
Still, you can turn it off and use the unit as intended.
Another benefit of this air purifier is that it’s relatively quiet, even in the strongest setting.
This is particularly beneficial as I don’t like when the air purifier is too loud because it can quickly get distracting.
And if you want the air purifier to get even quieter, you can put it on whisper mode.
Not everyone can splash out on an expensive air purifier for their basement.
If that sounds like you, I’ve got just the perfect model for you.
Please let me introduce you to the Pure Enrichment PureZone Elite air purifier.
Like my favorite pick from above, this unit has a multi-stage filtration system featuring a HEPA filter, UV-C light, and a carbon-activated filter.
In order words, 99.97% of solid particles as small as 0.3 microns can be removed while effectively removing odors, VOCs, and other gasses.
And while this model has an ionizer, it’s best not to use this feature if you want to maintain the highest safety levels possible.
This air purifier also has a smart air quality monitor.
This feature allowed you to view the quality of air currently present in the basement.
Also, your air purifier will adjust its settings automatically based on the quality of air in the basement.
In terms of this unit’s downsides, it only covers an area of 190 square feet, which isn’t ideal if you have an extra large basement.
It also has a set dBA rating of 60, which is quite loud compared to other quieter models.
After all, this is a budget-friendly pick, so I certainly can’t complain about these minor flaws.
Since I highlighted what is probably the best affordable air purifier on the market, it’s time to look at the other side of the spectrum.
If you want to spend a fair amount of money on one of the best air purifiers on the market, the TruSens Smart Wi-Fi air purifier is a great choice.
To start, this is a smart air purifier.
It can connect to your phone and other smart devices via Wi-Fi.
That way, you can tweak and adjust the unit’s settings remotely.
So, if you have smart speakers like Alexa at home, this air purifier is compatible.
In terms of its filtration system, this model is very capable.
For one, it can capture and destroy pollutants in 360 degrees thanks to its HEPA filter, carbon-activated filter, and UV-C light.
This unit can take care of everything from allergens and airborne viruses to cooking odors and pet dander.
What I particularly like about this unit is that it doesn’t have an ionizer.
While you can turn the ionizer off in the other two air purifiers on this list, it would be much more convenient if the air purifiers didn’t have the feature.
But that isn’t the only reason this air purifier stands out.
Another benefit of this air purifier is its automatic mode.
With the automatic mode, you can leave the air purifier on 24/7, and it will automatically adjust its settings depending on the air quality in your basement.
This air purifier also has a very modern and premium design, which could be what you need if you aren’t a fan of the classic tower-style air purifier.
That said, there is one flaw with this air purifier, and that’s the fact that it’s pretty expensive.
This is the priciest air purifier on this list, but rest assured that you get what you pay for.
When shopping for an air purifier for your basement, you want to ensure it has all the right features and functionalities.
And in the section below, I’ll outline what I think is important for your basement air purifier to have for it to do its job correctly.
The first and most important feature your basement air purifier should have is a true HEPA filter.
An air purifier without a HEPA filter is not worth it because it won’t be able to capture all the small solid particles floating around in the air.
This type of filtration system is made of fiberglass threads that form a fine mesh to capture tiny particles as small as 0.3 microns.
These particles include PM 2.5, dust, pollen, and other irritants that can be found floating in the air.
These are coincidentally the particles that affect our respiratory systems and can trigger asthma attacks.
So, buying an air purifier for your basement must have a true HEPA filter installed.
When shopping for an air purifier for your basement, you must also ensure it features a carbon filter.
This filter is designed to purify the air and free it from odors, smelly gasses, and VOCs.
Without this filter, though you’ll get purified air in your basement, that lingering basement smell will still be present.
In most cases, automatic modes on air purifiers are pretty unnecessary.
But this could be a handy feature if you plan on putting one in a large basement.
With an automatic air purifier, you won’t have to worry about adjusting the settings all the time.
Instead, these air purifiers use sensors to detect the air quality in the room and automatically adjust their settings accordingly.
With this feature, you can rest assured that the air in your basement is as purified as possible without the unit working harder than it should.
As a person with sensitive ears, I can’t stand the loud humming sounds some air purifiers produce.
So, if you’re someone like me, I highly suggest getting an air purifier with a relatively low noise output.
This feature allows you to hang out with friends and family in the basement while leaving the air purifier on without it being distracting.
I have an air purifier noise level guide that explains how loud your air purifier should be.
So, before you invest your hard-earned money into a unit, do make sure to check out my guide first.
This last feature is optional, but it would still be nice.
Most air purifiers rely solely on filtration to clean the air.
While this is great, some people would want more robust protection in the basement.
In that case, getting an air purifier with UV-C lights would be an excellent investment.
UV-C lights can eliminate bacteria and contaminants in the air, making for a much cleaner and safer basement.
It’s not uncommon for the basement to be the most stuffy room in your house.
After all, the lack of regular cleaning and proper flooring combined with adequate ventilation can contribute to low air quality.
Thankfully, air purifiers exist, and by getting a suitable model, you can take care of the quality of air inside your basement without spending a fortune.
Above, I shared my top 3 favorite air purifiers for large basements.
And honestly, no matter which model you go for, you can’t go wrong with them.
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.
There are several reasons why your air purifier can be loud. And below, I’ll go over some of the most common causes.
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.
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.
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.
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:
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.
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.
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.
School classrooms aren’t the best place to go if you’re looking for the cleanest air possible.
In fact, they’re pretty far away from it.
That’s why using an air purifier is highly advantageous in school environments where dozens of students and teachers mix up daily.
With that being said, not every air purifier can do the job.
So, to help you find the best air purifier for your classroom, I did a lot of research.
And in this guide, I’ll not only be showing you my top 3 picks but also things you should consider in an air purifier for a classroom.
But before I go ahead and do that, let’s look at how a school classroom can benefit from an air purifier in the first place.
Classrooms aren’t known to have the cleanest air inside.
For one, they are filled with many people simultaneously for an extended period.
On top of that, it’s pretty standard for schools to be in relatively packed and polluted districts.
And as air purifiers are designed to eliminate that polluted air, it’s easy to see how they can benefit the teachers and students inside the classroom.
Fortunately, most air purifiers are equipped with a high-quality HEPA filtration system to capture the smallest solid particles in the air.
Some air purifiers have activated carbon filters, which remove harmful smells and odors such as smoke, VOCs, and more.
That said, not every air purifier is suitable for a school classroom.
You want to get a model that has the air purification capacity of the size of the classroom, is silent when operating, features a minimalistic design, and more.
You can read more about the different things you should consider in an air purifier for a classroom at the end of this article.
But now, I want to show you the three best air purifiers for classrooms that I came across while researching this guide.
Not every air purifier is a suitable option for a classroom.
You want to ensure it has a suitable air purification capacity, that it’s relatively quiet when it works, and more.
After extensive research, I found the best air purifiers for school classrooms.
The first pick on this list is the BlueAir 411 Auto.
This is my favorite model on the market for several reasons.
It’s a simple, effective, and very quiet air purifier that outperforms other models in its price range.
To start, let’s take a look at the design.
I really liked this air purifier because of its simple design.
The straightforward design allows this unit to fit almost any classroom without stealing attention.
That way, you can place the air purifier just about anywhere in the room without worrying about distracting the students.
A barely noticeable light indicates that it’s working even when it’s on.
Another reason I like this air purifier is because of how easy it is to use.
When you have this air purifier, you have to turn it on with a touch of a button and leave it that way.
You don’t need to adjust any settings or touch any extra buttons.
This is because the air purifier automatically adjusts depending on the air quality in the room.
This means that the air purifier will work harder when more particles are in the air.
But if the air is relatively clean, the unit goes on a lower setting to maintain the air quality in the room.
Regarding its filtration system, the BlueAir 411 Auto features an H13 HEPA filter, one of the best on the market.
An H13 HEPA filter can capture up to 99.97% of solid particles in the room in sizes as small as 0.3 microns.
This way, if there are any students with asthma or allergies, they have an extra layer of protection when they’re in the classroom.
The one risk about having an air purifier in the classroom is that the noise can distract the students.
With this unit, you don’t have to worry about that.
This model is rated at just 18 dBA, significantly quieter than a whisper.
This means it’s practically noiseless unless you’re right next to it.
Before buying, you need to know a few things about this air purifier.
Firstly, this unit isn’t the best for covering larger spaces.
It can handle a maximum area of 190 square feet, which is enough for most medium and small classrooms.
However, if you have a larger room with many students, this model isn’t a suitable choice.
Additionally, it’s a bit pricey, like many BlueAir products.
But since it’s very quiet, has a smart operation, and has a simple design, it’s a worthwhile investment.
You don’t have to bust the bank to ensure you and your students breathe clean air.
If you want to buy an air purifier for the classroom, there’s no harm in spending a premium for a top-tier model.
But if you’re on a tight budget, quite a few models offer a great bang for your buck, such as the Levoit Core 300S.
In fact, I found this to be the best budget model for classrooms on the market today.
It comes with a real HEPA filter, operates very silently, has a simple design, and outperforms many other models in its price range.
So, this is the right pick if you want to buy a budget air purifier and get a lot of value for your money.
To start, let’s check out the filter.
This air purifier has a built-in H13 HEPA filter.
The filter can capture up to 99.97% of solid particles in the air, as small as 0.3 microns.
This air purifier would be great if you or your students have asthma or seasonal allergies.
Thanks to the HEPA filter, the dust and pollen will be captured and trapped inside the filtration system before it ends up in someone’s lungs.
Another aspect I really like about this air purifier is the design.
It’s simple and relatively small, meaning it won’t catch eyes or distract while easily fitting into any classroom.
On top of that, it’s a smart air purifier that can connect to your digital assistants like Alexa or Google Assistant.
This is great for classrooms as you won’t have to touch any buttons on the air purifier to adjust the settings.
All you have to do is use your phone or a smart device to change the settings.
Aside from that, it has excellent automatic settings.
So, even if you don’t want to use the digital assistants to control the settings, you can use the automatic mode, which adjusts depending on the air quality.
That way, you can turn the air purifier on at the start of the day and leave it until class ends.
And while this is also an affordable air purifier, it does have a downside.
This is a reasonably small air purifier, so it’s not a good fit for larger classrooms.
Besides that, it’s one of the best air purifiers for a classroom that you can get at this price.
The last entry on the list is my top recommendation if your school’s budget allows it.
You don’t have to pay a premium price for an effective air purifier, but there are some perks to buying some of the more expensive models.
This Coway air purifier is an excellent example of that.
The thing about this air purifier is that you can use it for larger spaces and move it from room to room.
This air purifier is designed for spaces up to 361 square feet, which is the most of any air purifier on this list.
And even if it’s a premium air purifier, it doesn’t have an overly complicated design.
As a result, this air purifier can blend in very nicely with any classroom in terms of size and design.
And for its size, this is a very quiet air purifier, averaging around 53 dB at its most powerful setting.
On top of that, this has a 4-stage filtration system, which means it will do a great job of purifying every aspect of the air.
That said, if there’s one downside to this air purifier, it has to be the price.
This is a fairly expensive air purifier. It isn’t the best option for those trying to buy an air purifier on a budget.
But if you’re looking to pay a premium for quality, this is one of the best picks.
There are a ton of benefits to using an air purifier.
I’ve already laid out some of the best air purifiers for school settings.
However, just knowing about the best choices isn’t enough.
It’s also crucial for you to understand the different features that make an air purifier suitable for a school classroom.
It also gives you a clearer picture of what makes an air purifier good in the first place.
So, here are some of the key considerations to keep in mind when buying an air purifier for the classroom:
A true HEPA filter is a primary feature you need in any air purifier for a school classroom.
HEPA filters are high-grade mechanical filters made out of fiberglass.
They are specifically designed to capture solid particles as small as 0.3 microns or 99.97% of all particles in the air.
When your air purifier has a HEPA filter, you won’t have to worry about dust, pollen, and other pollutants circulating in the air.
However, it’s also important to understand that there are quite a few types of HEPA filters.
Most HEPA filters are graded, and I only recommend getting air purifiers with an H13 HEPA filter or better.
These HEPA filters can offer some of the best protection against different pollutants.
And as a result, they are one of the best choices for anyone looking to improve the air quality of a classroom.
Though breathing clean air will benefit you and your students, the noise the air purifier will produce as a result certainly won’t.
That’s why you need to go for a silent air purifier.
This is especially true if you work in elementary schools or around children that can get easily distracted.
When I was back in school, the slightest noise outside would distract me, which is the case for most young people.
So, if you have a loud air purifier inside the classroom, you can imagine the harm it can do to the student’s focus.
Luckily, there are many low-noise air purifiers available on the market.
If you want an air purifier that doesn’t distract your students, I recommend getting one that operates at 30 dBA or less.
The lower the decibel rating, the quieter the unit will be.
You want your air purifier to benefit the people inside the classroom, not distract them.
This is why noise needs to be a primary consideration if you’re buying an air purifier for your classroom.
Smart features aren’t an absolute necessity, but they are a nice luxury to have.
If you have a smart air purifier, you’ll find it much easier to incorporate it into the classroom.
Smart air purifiers can be controlled remotely, meaning you won’t have to walk across the room just to adjust the settings.
That way, you don’t have to interrupt the lesson or momentum if the air purifier needs an adjustment.
My favorite smart feature is the automatic mode.
Essentially, the air purifier will automatically turn off when the air is as clean as it can be.
And when the air quality drops, the unit will turn back on.
That way, you can just let the air purifier be and not have to deal with it.
Getting an air purifier for a classroom is a great idea.
For one, it makes the air inside the classroom much safer for both yourself and your students.
As a result, children with allergies and asthma will have a much easier time, allowing them to focus on their studies solely.
That said, you must buy an air purifier with the right features.
In this guide, I’ve provided you with the best air purifiers for a school classroom.
And honestly, whichever one you decide to go for, you won’t be making a mistake.
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.
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.
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.
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.
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.
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.
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.
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.
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.
