Some air purifiers can remove allergens, others cigarette smoke, but far fewer can actually remove VOCs effectively.

I wanted to make it easier for homeowners to breathe clean air safely, so I compiled a list of the best air purifiers for removing VOCs.

In this guide, I’ll introduce them and help you find an air purifier that protects you and your family’s health.

Quick Glance - My Recommendations

  • Medical-grade filtration

PURO²XYGEN P500i - Air Purifier with H13...

PURO²XYGEN P500i

  • Recommended for harmful gases
  • Smart app included
  • Long Filter life - 3000 hours

CleanForce MEGA1000 Extra large Air Purifier...

CLEANFORCEAIR CP-MEGA1000

  • Quick VOC removal
  • Covers large homes
  • Great value for money

How I Ranked This List Of Air Purifiers

Volatile organic compounds (VOCs) can be dangerous in high concentrations, and 84% of homes in the US have higher concentrations of VOCs inside their home than outside.[1]

I tried and tested 30 VOC air purifiers in my home.

I compared their effectiveness, coverage, efficiency, and simplicity, eventually narrowing it down to the best.

Homeowners should understand that using an air purifier for VOCs is an excellent way to clean the air. The build quality and air purifier filter types impact the appliances’ ability the most.

Testing these products is great (in theory) but with so many variables, such as room size and varying types of pollutants its never going to be as concrete as some websites will have you believe.


11 Best Air Purifiers For VOC Issues

The VOC air purifiers listed below are at the top of the range. They all remove VOCs effectively and offer great value for money.

Some even have unique features that make them perfect for specific homes.

Who is the Medify MA-112 UV Light Air Purifier best for?

This Medify air purifier is best for those seeking to capture even the smallest particles in large spaces using the latest in HEPA H14 technology.

Pros
  • Covers a huge space
  • Excellent warranty terms
  • Medical-grade filtration
  • Aesthetically pleasing design
  • Super easy to operate touch panel
CONS
  • Loud on highest fan setting
  • Lacks smart features

The Medify MA-112 is my top choice because it 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 5,000 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 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, 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 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.

Pros
  • Targets harmful gases
  • Convenient app
  • Filter life of 3000 hours
  • Loads of smart features
CONS
  • Filters are expensive
  • Only 1 year warranty

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 further down on my list. 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.

Who is the CLEANFORCEAIR CP-MEGA1000 Air Purifier best for?

This Clean Force Air purifier is best for those with high volumes of VOCs and who want to manage them effectively.

Pros
  • Fast and effective VOC removal
  • Large coverage area
  • Great value for money
  • Tested and certified
  • Easy to use
CONS
  • The high noise level on some fan settings

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 IQAirMila Air, or Hathaspace 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.

CLEANFORCEAIR CP-MEGA1000 touchscreen

It may not be as cheap as the Okaysou or Nuwave models, but the quality and efficiency speak for themselves, and this air purifier stands out from the others I've tested.

If you want to control your air quality without breaking the bank, I recommend this air purifier.

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.

Pros
  • Advanced filtration system with unique patented bio-guard
  • Adaptive settings - more energy efficient
  • Wi-Fi enabled
  • Fast-acting with several fan speed settings
  • Perfect for large spaces
CONS
  • Slightly complicated to configure
  • Slow app

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.

It customizes the fan speed and settings for the current environment, making it as efficient as possible.

It's also Wi-Fi enabled with an app to control it. I found the app works okay but can be slow, and it's not as good as the Mila Air app.

NuWave 8001 wifi
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.

Who is the Mila Air Purifier best for?

The Mila air purifier is ultra-quiet and best used in bedrooms and nurseries.

Pros
  • Ultra-quiet operation
  • Effective at removing formaldehyde
  • Sleek and compact (this air purifier stands just 15 inches high)
  • 7 interchangeable filters
  • Cost-effective and energy-efficient
CONS
  • Smaller coverage
  • The app requires a lot of updates

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.

What surprised me most about this air purifier was how effective it was.

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.

Who is the IQAir HealthPro Plus best for?

The IQAir air purifier is best for pet owners and those with a variety of pollutants in their indoor air.

Pros
  • Tested and certified medical-grade HEPA filter
  • High-quality and long-lasting
  • 10-year warranty
  • Fast and efficient air purification and odor control
  • Long filter life
CONS
  • 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 hyperHEPA filtration removes ultrafine particles associated with viruses and bad odors, helping VOC removal by also removing contaminants that bond with them.

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 Okaysou and Austin Air Healthmate purifiers 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. 

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 Molekule Air Pro Air Purifier best for?

This advanced air purifier by Molekule is best for those who want to remove several types of pollutants from the air at once.

Pros
  • PECO filtration system to destroy contaminants
  • Medical-grade air purification
  • Smart features with a simple app
  • Sleek design
  • Energy-efficient air purifier
CONS
  • Pricey, and PECO filter replacements are expensive
  • Short warranty

The Molekule air purifier is modern, intelligent, and effective.

The advanced filtration system makes it easy to keep all pollutants out of your home, and it's one of the highest-performing models I have tested.

The efficiency comes from the filtration system. It combines a HEPA, carbon, and Photo Electrochemical Oxidation filter (PECO) to remove all contaminants.
Molekule Air Pro UV Light

The PECO filter uses UV light to destroy gaseous pollutants, giving you an extra layer of protection.

It's also equipped with high-tech features that make it easy to use. It's Wi-Fi enabled and has an app I actually thought performed really well (unlike the NuWave app). 

It even has an internal particle sensor that alerts you when it needs cleaning.

Unfortunately, all that technology makes it pricey. It isn't quite as expensive as the IQAir, but you will pay more for this model. 

However, this air purifier can handle a lot, and I think it's worth the cost.

This is the air purifier to buy if you suffer from a wide range of VOCs, allergens, and pollutants.

Who is the Alen BreatheSmart 75i best for?

The Alen Breathesmart 75i air purifier is best for allergy and asthma sufferers.

Pros
  • Medical-grade HEPA filter removes allergy triggers fast
  • Long filter life
  • Versatile with customizable settings
  • Equipped with smart sensor technology and auto mode
  • Energy-efficient air purifier
CONS
  • 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 4 pounds of activated carbon absorb over 99% of dust mites, pet dander, VOCs, and other asthma and allergy triggers.

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.

Alen BreatheSmart 75i blue light

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.

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.

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.

Pros
  • Easy to move and store
  • Low energy consumption
  • Easy to use
  • High volume of activated carbon to trap all airborne pollutants
  • Medical grade filtration removes particulate pollutants
CONS
  • Bit noisy
  • Not suitable for very large rooms

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 the AlenMolekule, or IQAir purifiers.

Austin Air HealthMate filter
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, it’s lightweight and easy to use.

It has caster wheels to roll between rooms and intuitive touchscreen controls that make 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. but in their review,

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 Okaysou AirMax10L Pro Air Purifier best for?

The Okaysou AirMax10L Pro air purifier is best for those on a tight budget.

Pros
  • Really affordable
  • An effective filtration system removes the tiniest particles
  • Intuitive controls and user-friendly features
  • Quiet operation
  • Eco-friendly with low running costs
CONS
  • Less durable
  • Needs regular cleaning

VOC air purifiers can be expensive, but Okaysou offers quality air purification without the big price tag. 

This air purifier is low-cost to buy and run and far cheaper than the others on the list.

It also has less energy consumption than other models, so you'll save money on your monthly energy bill.

Despite the lower price, I was still impressed with how the purifier performed.

It has a 5-stage filtration process, including a unique 'nanois' filter that effectively captures larger particles as the air passes through it.

The Okaysou doesn’t have the same CADR or power as the NuWave or Clean Force Air but will still remove up to 99% of all VOCs (including formaldehyde), bacteria, and viruses.

Outside the low costs, I appreciated the user-friendly features built into the appliance.

It has a child lock to prevent children from accidentally changing the controls, automatic sensors to adjust the air purification settings, and even a sleep mode.

Okaysou AirMax10L child lock

It may not have all the bells and whistles of the IQAir, but it still makes it easy to remove VOCs.

The Okaysou air purifier did well in my performance tests. Still, it is lower quality than the other models on the list. However, it is a lot more affordable.

If you want a shorter-term solution to remove VOCs on a budget, this is the model I recommend.

Who is the Airpura F600 And F600DLX best for?

The Airpura air purifier is best for those who want a low-maintenance model.

Pros
  • Low maintenance
  • Great for large, open spaces
  • VOC specialist air purification - high level of activated charcoal
  • Customizable settings
  • Quiet operation
CONS
  • Expensive with an expensive filter
  • Fairly high noise levels

I love playing with new gadgets and home appliances, but I appreciate that many homeowners want an appliance that works with minimal effort.

That’s why the Airpura is on the list.

This air purifier is so simple that anyone can use it. It has straightforward touchscreen controls, a remote control, and easily configurable air purification settings. It’s also easy to maintain and requires little cleaning.

There aren't many premium air purifiers you can just set and forget, but this is one of them.

Don't let the simplicity fool you, though, because this is a high-performing VOC specialist device.

The high volumes of activated carbon trap and lift all VOC, bacteria, and viruses, leaving you with safe and clean air.

It’s also customizable with different filters (like the Mila Air model), so you can add extra layers of filtration to match your specific needs.

The thoughtful design, user-friendly features, and effective filtration make this the perfect air purifier to reduce VOC levels in larger spaces. 

The only drawback is the price because this model is even more expensive than the IQAir.

However, if you want a high-quality, low-maintenance, and durable appliance that will purify the air without a second thought, this is the one I recommend.

What To Look For When Buying A VOC Air Purifier

How Much Activated Carbon Is In The Filter?

All the best air purifiers have an activated carbon filter, but the volume of activated carbon (or activated charcoal) will vary.

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.

how do air purifiers work

Smaller portable air purifiers will only have a few ounces of carbon. 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/activated charcoal.

TL;DR: Activated carbon filter is the most important component for cleaning VOCs and harmful gases. The more activated carbon an air purifiers has, the more efficient it will be at removing VOCs.

CADR Score Is An Important Parameter

What is CARD Rating

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.[2]

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 score I recommend for different-sized rooms:

  • 100+ for a small room size (up to 155 sq ft)
  • 150-200+ for a medium room size (155 to 310 sq ft)
  • 300+ for a large room size (310 to 465 sq ft)

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?

TL;DR: The higher the CADR, the more efficient the unit is at removing harmful gases and particles from the air.

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.[3]

Certification isn't mandatory, but it does let you know the product has been through testing. 

If you want a highly certified air purifier, I recommend a model like IQ Air HealthPro Plus or Clean Force Air.

TL;DR: The highest quality air purifiers have specific certifications for VOC removal. Look for these.

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.

Alen Breathesmart Air Quality Sensors

TL;DR: Modern air purifiers have sensors for detecting harmful gases and VOC in the air.

Durable Construction Is Paramount For VOC Purifier

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.

TL;DR: Always look for air purifiers from a reliable brand with durable and high quality construction when dealing particularly with VOCs and formaldehyde.

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.

Alen Breathesmart Noise Level

TL;DR: Air purifiers are generally quite. However, if you are sensitive to noise, then look for quieter units.

How Easy Is It To Operate

Air purifiers dealing with VOCs can be complicated.

I recommend looking for a model with basic controls and low maintenance.

If you're a beginner, I recommend the AirPura or Austin Air Healthmate, as they are both very user-friendly.

TL;DR: If you do not want to deal with complicated controls, look for units that are easy to operate.

Up Front Costs Can Vary

A high-quality VOC air purifier will typically cost $400-$600.

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.

If you're on a tight budget, I recommend the Okaysou model. It offers premium quality at a relatively low price and has low running costs.

TL;DR: Air purifiers designed to deal with VOC and formaldehyde are generally more expensive as compared to generic HEPA air purifiers.

Warranty - The Longer The Better

lways get a warranty on a VOC air purifier. They are expensive home appliances (because of the activated carbon filter and HEPA filters), and you should look for at least a 1-year warranty.

Ideally, look for a premium model with a longer warranty, like the IQAir Health Pro Plus, which offers 10 years of protection.

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.[4]

Common Indoor VOCs

  • Formaldehyde
  • Benzene (particularly in cleaning products)
  • Toluene
  • Acetone

Volatile Organic Compounds can come from many places, including paint, cleaning products, furniture, and other building materials.

Symptoms Of VOC Exposure

Exposure to high concentrations of VOCs can cause:[5]

  • Eye, nose, and throat irritation
  • Nausea, headaches, and dizziness
  • Increased risk of cancer, liver, and kidney damage
  • Damage to the central nervous systems
  • Triggering of asthma and allergies
  • Exacerbated respiratory problems

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 detect them, you need to take action immediately.

TL;DR: VOCs are some of the most harmful gases that you can be exposed to. From paint to cleaning products, VOCs can be found in many products. VOC can lead to acute as well as chronic health conditions if exposed for a long time. 

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:

  • Absorption
    The best air purifiers for volatile organic compounds have an activated carbon filter. These adsorb airborne particles and trap VOCs, leaving you with fresh air in your home.[6]
  • Filtering
    All air purifiers have filters to remove dust, allergens, pollen, pet dander, and other airborne particles from the air. Volatile Organic Compounds can often attach to dust and other impurities, so the filtering should remove some VOCs.
  • UV Photocatalytic Oxidation
    Some modern air purifiers use UV light to deal with VOC airborne particles.[7] The light and a catalyst oxidize the VOCs, transforming them into less harmful compounds.
  • Improved Ventilation
    Air purifiers increase airflow, stopping VOCs from clustering in your home and removing bad odors.
An air purifier with an activated carbon filter is needed to deal with VOCs.

However, many modern air purifiers offer carbon, HEPA, and UV air purification in one.

TL;DR: Air purifiers have several filtration stages such as HEPA, activated carbon and UV for cleaning the air. For VOCs, the most important filtration stage is the activated carbon.


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 models may last over 10 years if properly maintained.

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 Medify MA-112 UV 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.
