Many air purifiers claim to clean the air, but when it comes to tackling VOCs like formaldehyde or benzene, most fall short.
Removing these harmful chemicals requires more than a basic HEPA 13 filter—it demands a purifier designed specifically for the job.
In this guide, I've narrowed down everything you need to choose an air purifier that safeguards your home and your family’s health from VOCs.

Who is the Austin Air HealthMate best for?
This easy-to-move air purifier by Austin Air is best for homeowners who need purification to remove gases and smoke.
What you will like
What you won't like
I use my air purifier daily, but many homeowners only need an air purifier at certain times of year.
The Austin Air Healthmate is the perfect solution, offering efficient filtration and portability, letting you remove airborne contaminants when and where you need to.
Austin Air produces first-rate home appliances, and they are one of my go-to brands.
This air purifier has a high-quality HEPA filter and almost 15 pounds of activated carbon- more than any other air purifier on my list.

The higher volume of activated carbon means it can remove more VOCs and gaseous pollutants from your home.
Alongside the efficient filtration and air purification, its easy to use.
I need to note that the product listing for this one says that the unit weighs 15 pounds, but that's just the activated carbon filter! The actual weight of the product and filter weigh 47 lbs. together.
It has caster wheels to roll between rooms and an intuitive touchscreen that makes it easy to configure. There is also a remote control, but I didn't really need it during testing.
The Austin Air Healthmate is a premium VOC air purifier, so it's more expensive, compatible with the price of the Alen Air Purifier.
Still, the Deccan Herald states this air purifier has 'unmatched gas filtration'
However, it delivers commercial-grade filtration and costs about the same as the Alen and Clean Force Air models.
If you want a high-quality, portable air purifier that will last years, this is the one I recommend.

Who is the IQAir HealthPro Plus XE best for?
The IQAir air purifier is best for pet owners and those with a variety of pollutants in their indoor air.
What you will like
What you won't like
- Pricey, with expensive replacement filters
- Higher energy consumption
The IQAir purifier is high-quality and high-performing. It's medically certified, too, so I know it will keep my indoor air clean.
It may not have the coverage or CADR of the NuWave or Clean Force Air. Still, it's arguably more efficient, and this smart air purifier stands up to heavy use.
The unique hyper HEPA filtration removes ultrafine particles associated with viruses and bad odors, helping VOC removal by also removing contaminants that bond with them.
According to IQAir, "IQAir's HyperHEPA filtration is proven and certified to filter at least 99.5% of all particles down to 0.003 microns - which is 100 times smaller than the 0.3 micron particles that HEPA filters can remove."
The advanced air filtration system also works fast.
It uses a 360-degree powerful fan system that evenly distributes air around a room, improving the overall air quality more quickly than other models.
The only downside of this high-performing air purifier is the cost.
It's noticeably more expensive than the Austin Air Healthmate purifier and not for those on a tight budget.
However, it offers industrial-grade quality and will last over a decade if well maintained, offering long-term value for money.
The other feature I love is that IQAir recently updated this model (the new XE tag). The new model integrates WiFi connectivity through the AirVisual app, making it easy to track your air quality from anywhere.
If you have pets or live in an area with a lot of pollution in the air, I recommend the IQAir HealthPro Plus.

Who is the Alen BreatheSmart 75i best for?
The Alen Breathesmart 75i air purifier is best for allergy and asthma sufferers.
What you will like
- Equipped with smart sensor technology and auto mode
What you won't like
- Requires a subscription to activate the warranty
- Replacement filter is expensive
The Alen BreatheSmart packs a lot into a small frame, and I was surprised at how well it performed.
The medical-grade HEPA filter and activated carbon absorb over 99% of dust mites, pet dander, VOCs, and other asthma and allergy triggers.
However, it's important that I note that Alen has several filters for the 75i, and the Fresh filter is the only one suitable for VOCs.
It also provides odor control, leaving your home feeling and smelling fresher.
I found the Alen Breathesmart more versatile than other VOC air purifiers, with several different settings and modes.
It even has a customizable front panel to match the style of the room.
However, my favorite feature of the Alen Breathesmart air purifier is the Smart Sensor technology.

It detects the current air quality accurately and has display lights on the front panels to indicate when it's cleaning the air. It even has app control and displays all the readings.
The adjustable settings, sensors, and auto mode mean it mostly runs itself, and over two days of testing, I didn't have to do much.
It isn't the cheapest model, but it's priced competitively for a premium quality air purifier at about $800.
It may not have the raw power of the Clean Air Force, but this versatile air purifier is more than enough for most homeowners with allergies.
I also really appreciate that when you subscribe to filter replacements directly through Alen Air, you not only save 10%, but they also extend your 1 year warranty into a lifetime warranty.

Who is the Medify MA-112 UV Light best for?
This Medify MA-112 is best for those seeking to capture even the smallest particles in large spaces using the latest in HEPA H14 technology.
What you will like
What you won't like
The Medify MA-112 is an absolute powerhouse of an air purifier.
If you’re dealing with VOCs or pollutants in a really big space, this one will definitely have you covered.
That’s because the MA-112 can cover up to 4455 square feet in just one hour when set at the top fan speed. That’s way more than any other purifier on my list, with the Clean Force Air coming in closest at 3000 square feet.
This is even the purifier that I recommend to office buildings dealing with local wildfires, as it just has such potent coverage.
Of course, that coverage does come at a cost – both with the actual price of almost $600 and with noise levels.
On the highest fan speed, you can expect the Medify to run at about 70 dB. This sound is comparable to a washing machine. I definitely wouldn’t want to be sitting right next to this one and having to make a phone call.

That said, the combination of pre-filter, HEPA H14 filter, and carbon filter cleans the air really fast, with a CADR of 950.
Once the purifier had been running for a couple of hours, I found that I could reduce the fan speed. The lowest fan speed is super quiet.
While most air purifiers now have HEPA filtration, short for "high efficiency particulate air" filter, I appreciate Medify’s commitment to using the most high-quality filters in their purifiers.
H14 purifiers have medical-grade air filtration and are what you will find most hospitals using.
The UV light is also a nice addition, although the jury is still out on if this feature offers true benefit, at least in my opinion.
At this price point, I would have liked to have seen an air quality indicator like on the Alen BreatheSmart. Still, if you’re looking to purify an extra-large space, you can’t beat the power of the Medify MA-112.

Who is the PURO²XYGEN P500i best for?
The P500i air purifier is best for those seeking an air purifier with a cold catalyst filter to specifically target harmful gases.
What you will like
What you won't like
For those who don’t quite need the power (or the price tag) of the Medify MA-112 but who still want to target VOCs in a smaller space, let me introduce the PURO²XYGEN P500i.
This is the only product on my list that uses a cold catalyst filter.
A cold catalyst filter is specially designed to both absorb and decompose formaldehyde and other harmful gases (like Benzene, TVOC, and even ammonia).
This filter, combined with the HEPA H13 filter, carbon filter, and mesh pre-filter, does a pretty solid job of cleaning my 800-square-foot open-plan apartment.
Technically, the PURO²XYGEN is rated for 1650 square feet, but reading the fine print will show you that it takes approximately three hours at that capacity, which is why I recommend it for apartments or even bedrooms.
Performance-wise, the coverage is similar to the Austin Air Purifier. PURO²XYGEN comes out way ahead though, both in aesthetics and extra features.
I love that I can see my air quality and filter status in real time, which has saved a ton of guesswork.
Not only that, but it also has a handy app that allows me to control the purifier from virtually anywhere with a WiFi signal.
I found the app easy to use and less finicky than the one that pairs with the NuWave model.
Overall, if you’re looking for a purifier with cold catalyst technologies, the PURO²XYGEN is the top of the line.
I only need to stress that the filters should be replaced with name-brand filters by PURO²XYGEN because there are a lot of knock-offs out there that I’m sure don’t offer the same benefits.

This Clean Force Air purifier is best for those with high volumes of VOCs and who want to manage them effectively.
What you will like
What you won't like
The Clean Force Air makes short work on VOCs and other pollutants. It's my top pick because of the quality, effectiveness, and value for money it offers.
It has a higher CADR rating than any other air purifier I tested and has several stages of filtration.
The pre-filter, True HEPA filter, and activated carbon filter remove over 99% of VOCs and other pollutants that have made their way into your home.
It also has a large coverage area and can purify air in a bigger space than the IQAir or Mila Air models.
Clean Force Air works quickly thanks to 360 coverage and a range of fan speed settings.
It improved the air quality in my 1500-square-foot workshop in under 30 minutes during testing, and even in a larger area, it works fast.
What I really like about this high-performing air purifier is its simplicity.
It has touchscreen controls, smart sensors, and automatic settings, so it's easy to configure and run.

It may not be as cheap as the Nuwave model, and is almost $600, but the quality and efficiency speak for themselves, and this air purifier stands out from the others I've tested.
The company also prides itself on being based in California, which has some of the strictest air quality regulations, mandated by the California Air Resources Board (CARB).

Who is the NuWave 8001 Air Purifier best for?
The NuWave air purifier is best for large spaces and homes that need fast air purification.
What you will like
What you won't like
The Nuwave air purifier is extremely effective at removing volatile organic compounds over large areas.
The advanced filtration system (with five different layers of protection) works against dust mites, pet dander, mold spores, and VOCs, giving you fresher air in your home.
This air purifier is equipped with air quality sensors to gauge the pollution levels and automatic adaptive settings.
The Nuwave customizes the fan speed and settings for the current environment, making it as efficient as possible.
It's also WiFi enabled with an app to control it called Nuwave Connect. The nice thing is that if you have other Nuwave products like their air fryers, you can control all of your devices from one place.
I found the app works okay but can be slow, and it's not as good as the Mila Air app.

What impressed me most was the speed of this air purifier. I tested it in my 2500-square-foot garage, and it took under 20 minutes to improve the air quality.
It's perfect for large open spaces, garages, workshops, or apartments requiring air purification.
The Nuwave is slightly more expensive than the Clean Force Air model but still cheaper than other air purifiers.
It offers good value for money, and I recommend it for those who want to manage the indoor air quality in a large home or open space.

The Mila air purifier is ultra-quiet and best used in bedrooms and nurseries.
What you will like
What you won't like
The Mila air purifier is functional but unobtrusive. It's whisper quiet and runs at under 25 decibels - the equivalent of gentle breathing - with a compact and sleek design.
It fits into any home and is perfect for bedrooms, nurseries, or studies where you want clean air without any disturbance.
In fact, it's so impressive that Mila Air has specifically marketed the product to expectant mothers who are "breathing for two."
I usually find that quiet models have less impact, but during testing, it removed over 92% of the VOCs from the air in my test room in under 2 hours.
It may not have the same power as the NuWave or Clean Force Air models, but it's really effective at cleaning the air in small spaces.
The stand-out quality for me with this air purifier was the versatility.
It has seven compatible filters, each designed to deal with different pollutants.
The "critter cuddler" activated carbon filters are best for removing VOCs, but the others are useful for pet dander, dust mites, or other contaminants.

The Mila Air is smart, simple, and silent. If you need quiet VOC removal, it's the one I recommend.

Formaldehyde and VOC air purifiers compared
What to look for when buying a VOC air purifier
How much activated carbon is in the filter?
All the best air purifiers for VOCs have an activated carbon filter, but the volume of activated carbon (or activated charcoal) will vary.
Studies have revealed that more carbon means more adsorption and removal of VOCs.
Generally, the amount of activated charcoal or carbon is relative to the size of the air purifier.

Smaller portable air purifiers will only have a few ounces of carbon, and filterless air purifiers won't have any, which is why they aren't great for odors.
Larger high-end air purifiers with a large filter may have 5-10 pounds of activated charcoal or carbon.
More activated charcoal or carbon means more effective air purification, but it also means the air purifier is more expensive.
It may also impact the filter life span.
I recommend balancing cost with performance by choosing a model like the Clean Force Air, but you can opt for a purifier like the Austin Air Healthmate with more activated carbon or activated charcoal.
CADR score is an important parameter

CADR stands for Clean Air Delivery Rate.
It’s an indicator of the effectiveness of an air purifier, showing the cubic feet per minute (CFM) of clean air delivered in a room and the amount of pollutants removed.
The CADR should be clear on the packaging.
CADR is actually a measurement of air purifiers ability in removal of cigarette smoke, dust, and pollen rather than VOCs.
However, it still shows what you can expect from your air purifier. These are the minimum CADR scores I recommend for different-sized rooms:
If you want a larger CADR that can quickly improve air quality in any room size, the Clean Force Air is a solid choice.
Related article: What is CADR rating?
Check for VOC removal certifications
Some regions will have official certification to show that an air purifier can remove specific VOCs (particularly formaldehyde).
The California Air Resources Board (CARB) is one of the most common, but it does vary from region to region. CARB has the most strict regulations, so if your air purifier is on their list of certified models, you know you can trust it will work well.
Certification isn't mandatory, but it does let you know the product has been through testing.
Air quality sensors for improved efficiency
Many modern air purifiers can sense poor air quality and activate as needed.
It's useful because it improves the efficiency of the air purifier and (by sensing and removing airborne particles and VOCs) gives you cleaner air.
You will pay more for an air purifier with smart features and sensors, but I recommend it.
Models like Alen Breathesmart or Nuwave have some of the most accurate sensors.

Durable construction is paramount for VOC purifiers
Quality should be standard in home appliances, but it's particularly important for VOC air purifiers to prevent air leakage.
Look for a well-made appliance with well-sealed edges around the filters so no VOCs can escape or bypass the filter.
A high-quality air purifier will be more efficient and safer, preventing air leakage and VOCs going back into your home.
All the models listed above are good quality and well made, but quality does cost more. Don’t be afraid to spend extra on a VOC air purifier compared to standard models.
Related article: Are air purifiers safe?
Beware of the noise output
A noisy air purifier is a nuisance in any home, particularly if you have VOCs, because you'll have to run the air purifier for longer (potentially 24-7).
I recommend a quiet model with a noise level under 50 decibels to avoid unnecessary disturbance.
Brands often list the decibel rating (noise level) on the lowest fan setting, not the highest fan speed, and there can be a big difference.
Remember, check the decibel rating on all fan speeds to see the actual noise level.
If you need a quiet model, I recommend the Mila Air purifier. It has a powerful fan but produces a noise level of under 35 decibels at all fan speeds.

Up front costs can vary
A high-quality VOC air purifier will typically cost $400-$1000.
They cost more than a standard air purifier because they need more specialist adsorption or filtration, so you should be ready to pay more.
It’s also worth considering the energy consumption of the air purifier models and how much they will cost to run.
Investing in an efficient unit with sleep mode can help you save money on your bills.
What exactly are VOCs and why air purifiers can help remove them
Volatile Organic Compounds (VOCs) are harmful chemicals that easily evaporate at room temperature and end up in your air supply.
Common indoor VOCs
Volatile Organic Compounds can come from many places, including paint, cleaning products, furniture, and other building materials.
Symptoms of VOC exposure

You can sometimes tell you have high concentrations of VOCs due to household odors, but it's often impossible to know.
I use an air quality monitor to detect VOCs, and I recommend you do the same.
If you have symptoms, you need to take action immediately.
The Minnesota Department of Health says that people with respiratory problems such as asthma, young children, the elderly and people with heightened sensitivity to chemicals may be more susceptible to irritation and illness from VOCs.
How air purifiers remove VOCs
Air purifiers can help remove Volatile Organic Compounds and improve indoor air quality.
Depending on the type of air purifier you have, they can help in a few ways:
An air purifier with an activated carbon filter is needed to deal with VOCs. Purifiers with washable filters will not be suitable enough.
However, many modern air purifiers offer carbon, HEPA, and UV air purification in one.

FAQs
How do air purifiers for VOCs and formaldehyde work?
Air purifiers with activated carbon remove VOCs and formaldehyde through adsorption.
The activated carbon has tiny pores and is highly effective at attracting VOC molecules. The VOCs diffuse into these pores, removing them from the air stream.
How long should I run a VOC air purifier for home air filtration?
A VOC air purifier should be run until the air is clean, which could be 24-7. At a minimum, it should run for 8 hours, but I recommend buying a smart VOC air purifier with built-in sensors so it can run as and when needed.
How long will air purifiers for VOCs last?
It varies depending on the quality of your air purifier, but they typically last 5-7 years. Higher-end and whole-house models may last over 10 years if properly maintained.
Related article: Top-rated air purifiers for whole house use
What does off-gassing mean?
Off-gassing is when new items in your home (furniture and other common household products) release VOCs and other chemicals into the air.
Ventilation or air purification can help to remove the off-gassing effectively.
Will a HEPA filter remove VOCs from the air?
No, while HEPA filters are highly effective at removing the tiniest particles of dust, pollen, pet dander, and other allergens, they can’t remove VOCs from the air.
You need an activated carbon filter to remove VOCs effectively.
So, which should you buy?
Only VOC air purifiers can properly handle certain harmful chemicals in your air.
All the air purifiers on the list above are up to the job, but the Austin Air Healthmate air purifier is my top pick.
It's high-performing, efficient, simple, and covers a large area. It will improve the air quality in any home and won't break the bank.
However, every home has different needs, and you may benefit from a different model.
Hopefully, this list has helped you find the best VOC air purifier so you and your family can enjoy fresh, clean air.
