Volatile organic compounds, or VOCs, regularly enter the home when you paint, clean, or even buy new furniture. The term ‘VOCs’ stands for volatile organic compounds, which are chemical gases emitted by some solid or liquid objects and can contain various chemicals, some harmful to human health.
Many VOCs are human-made chemicals used and produced in manufacturing pharmaceuticals, paints and refrigerants. VOCs can be created through chlorination in water treatments and contained in industrial solvents, pesticides, building materials and fuel.
These VOCs can enter our homes through common household products you use daily, such as paints, cleaning products, perfumes and nail polishes, among many others. And they can also enter our offices, through equipment like printers and photocopiers.
According to the U.S. Environmental Protection Agency, VOC concentrations can be up to ten times higher indoors than outdoors. Outside, VOCs usually dissipate without causing any harm. But, when indoors, these chemicals can linger and cause adverse health effects ranging from headaches and throat irritation to kidney and liver damage.
“As with any issues relating to your air, try to ventilate your house as much as possible, especially when using VOC-heavy chemicals like paint stripping or cleaning products. Make sure to open doors and windows to get more air moving inside your home.”
— Danny Ashton, Founder & Senior Writer
When this isn’t possible, another method of reducing VOC levels is using an air purifier that uses adsorption technology, usually with the help of a filter made of activated carbon.
To help, we have hand-picked our top recommendations for tackling VOCs indoors.
| Why You Can Trust Our Recommendations When shortlisting the best air purifiers available to help deal with volatile organic compounds indoors, we focused on three main features: ✅ Packed activated carbon filters. The larger the Activated Carbon filter, the more VOCs can be removed. ✅ Powerful air cleaning performance. If you have no choice but to paint your house or clean using powerful chemical products, then you need to know that your air purifier will be efficient and fast at cleaning the air while you work. ✅ Medical-grade HEPA filters. H13 HEPA is the perfect grade of HEPA for removing the tiniest particles, including bacteria and viruses. Unlike other comparison lists, we have tried and tested each air purifier we recommend. We don’t just rely on manufacturer specifications; we put each unit through its paces. Our home testing includes 1️⃣ Measuring a unit’s air cleaning performance using an air quality monitor. We do this by tracking the time it takes to remove incense smoke pollutants from our testing room (705 ft. sq.) 2️⃣ We monitor how much energy they use at the lowest and highest fan speeds using an electricity usage monitor. 3️⃣ Using a sound level monitor, we monitor each air purifier’s noise level output (dB) running at the lowest and highest fan speeds. |
It’s important to clarify that most popular air purifiers are aimed at other air quality issues, such as pollen or cigarette smoke. Many top sellers won’t be as effective at dealing with VOCs unless packed with a large, activated carbon filter combined with a high-quality HEPA filter.
That is why you will see some units we don’t usually recommend here at HouseFresh that might not be the best for common household uses, but that will be highly effective against VOCs.

Read on to learn more about the six air purifiers we recommend for those looking to tackle VOCs indoors.
Sadly, the most popular small air purifiers that are brilliant at removing particle pollutants don’t have the required amount of activated charcoal needed to deal with a significant issue with VOCs, so I would avoid these units for most people looking to remove VOCs from the air.
1. HouseFresh Pick: IQAir HealthPro Plus
The IQAir HealthPro Plus is built to remove small particles, odors and VOCs. Its powerful filtration system captures ultrafine particles as small as 0.003 microns and its HyperHEPA technology stops at least 99.5% of these particles and pathogens.
The IQAir HealthPro Plus has a large filter packed with nearly 5lbs of activated carbon. Combined with their HyperHEPA technology, this unit is the most efficient air purifier for tackling VOCs indoors.
Everything is kept airtight with this unit too. The filters are 100% sealed to prevent any air leakage. It offers 320° air delivery with minimum noise output on the lowest fan setting. There are six fan speeds in all, and it comes with a compact remote so you can adjust the speed, set up a timer and power the unit on and off.
What We Really Like:
👍 IQAir has been creating air purifiers since WW2, so they are a trusted brand that knows everything there is to know about air purification
👍 An expert team tests every unit in Switzerland before it gets shipped to the customer
👍 No ionizer function, meaning the HyperHEPA technology + real activated charcoal pellets do the job without generating ozone
👍 Great choice for those with medium to large-sized rooms
What We Think Could Be Better:
👎 This unit isn’t small by any means, so it needs a lot of room
👎 Filter costs are high, as are electricity costs

2. Best for Larger Spaces: Austin HealthMate
Austin Air Systems has been producing high-quality air purifiers since 1990 and has been voted the number air purifier made in the USA by HouseFresh experts. Their specialty is creating high-priced units focused on VOCs and chemicals — a niche in the air cleaning sector that most popular air purifier brands usually ignore.
The Austin Healthmate comes with a filter with 15 lbs of activated charcoal, nearly three times the amount of activated charcoal that even the biggest air purifiers will include. A medical-grade HEPA filter can remove up to 99% of airborne pollutants as small as 0.1 microns, making the HealthMate able to deal with VOCs, bacteria, dust and other allergens.
Even though the HealthMade doesn’t come with any auto or sleep functions that other cheaper units include (hello, TaoTronics AP003), this air purifier stands out by its sheer performance regarding chemicals and odors.
What We Really Like:
👍 The most amount of carbon you can get for this price point (which we know is key for tackling VOCs effectively)
👍 The 5-year warranty is not something you see often
👍 The filters last a good amount of time before needing to be replaced (60 months)
👍 It is simple to use, without bells and whistles
What We Think Could Be Better:
👎 No auto or smart mode
👎 The design is very boring would like to see more innovation in future models
SPECS & FEATURES

Mila is a smart air purifier that delivers. The moment you turn on your Mila, the air purifier analyzes the needs of your space with the help of its onboard air quality sensor, which can detect VOCs, CO2, CO1, PM1, PM2.5 and PM10 in real-time.
You can pick from several customizable filters when buying a Mila Air Purifier. Make sure to choose The Overreactor (the actual name of the filter) because it comes with 1.96 lbs of modified granular carbon. Hence, it is better equipped for dealing with volatile organic compounds (VOCs) and other chemicals.
The Mila performed well in our air cleaning test and cleaned the air from incense smoke pollutants in our home lab in under 35 minutes. This is the same cleaning power we saw in the Levoit Core 400S, but the Mila has a better filter option for VOCs.
Another benefit of this unit is that it looks great. This means you can set the unit up in different rooms around your home without wasting too much space or ruining your home décor.
What We Really Like:
👍 Excellent in-built air quality sensor
👍 Smart home features that make it easy to use
👍 A good option for large rooms (up to 1000 sq. ft.)
👍 Great looking design and good size
What We Think Could Be Better:
👎 You pay a lot for the fact that it is a smart unit

4. Smart Blast Mini
Smart Air may not be as well known in the air purifier market as some of the more prominent brands. Still, they’re making big waves with their high-performance units focused solely on cleaning the air in your home over fancy smart features and gadgetry.
The Blast Mini is one of their finest examples of a unit that can easily tackle VOCs in rooms up to 915 sq. ft. with its huge fan and powerful motor that produces an impressive CADR score of 435 CFM.
Encased in its durable metal exterior is a large medical-grade H13 HEPA filter to capture harmful airborne particles in your home.

5. Alen BreatheSmart 75i
Alen has been producing Ture HEAP air purifiers that everyone trusts and rates highly since 2005, and the Alen 75i is the flagship model of their bestselling air purifiers.
When buying an Alen BreatheSmart 75i, you will be prompted to choose a filter from three options designed to tackle different air quality issues. When purifying the air from VOCs, you have to go for Alen’s B7-Fresh True HEPA Filter, which comes with an H13 True HEPA filter plus the power of activated carbon for added protection against volatile organic compounds (VOCs).
As with the other air purifiers we recommend for VOCs, the Alen BreatheSmart 75i doesn’t come cheap but if you do pick the subscription service for filters, they will give you a lifetime warranty on all of their air purifiers when you buy from Alen.com
We still have an Alen A350 from 2010 that performs pretty well if a little energy-inefficient so you can expect their purifiers to keep running for the long term.
What We Really Like:

6. Airpura F600 and F600DLX
Suppose you thought Austin HealthMate was incredible for packing their filters with 15 lbs of activated carbon. In that case, you will be shocked to learn that the Airpura F600 comes with a whopping 26 lbs of activated carbon when opting for the F600DLX model. Combining a medical-grade HEPA filter with a large amount of activated carbon is a vital part of the battle over VOCs and the Airpura F600 does this all with a fan capable of 560 CFM.
We didn’t choose this unit as our top recommendation because the price is astronomical for most households. You are unlikely to need an air purifier like this unless you have a severe issue with formaldehyde or your work forces you to be close to chemical gasses and VOCs.
The Airpura F600 is expensive regarding the initial purchase and its replacement filters — the carbon filter alone costs around $279!

Buying Guide: Air Purifiers for VOCs
From irritating your eyes and throat to damaging your organs and nervous system, the dangers of VOCs can be severe and must be addressed. Your best option is to pick an air purifier specifically designed to absorb these hazardous chemicals.
But how do you find the best air purifier for VOCs? We’ve got you covered. This guide will introduce you to VOCs and where they come from in your home. We’ll also explain why activated charcoal is the best for VOCs like formaldehyde. Let’s dive in!
| 🤔 Can VOCs make you sick? When we speak about VOCs, many of them are ubiquitous pollutants that can be found in any home. You will have a higher chance of being exposed to these while sitting inside your home than you ever will be while going outside. Many of them can vaporize at room temperature, but they can potentially harm your health if they are in high concentrations. How harmful also depends on how long the exposure has been going on. The Environmental Protection Agency reports regular or prolonged exposure to these volatile organic compounds or VOCs can have nasty health implications. They may include: – Eye, nose and throat irritation – Headaches, loss of coordination and nausea – Damage to the liver, kidney and central nervous system – Some organics can cause animal cancer, while others are suspected or known to cause cancer in humans. Common sources of VOCs in the home include: 🚧 Building materials — VOCs can be found in paint, caulks, adhesives, vinyl flooring, insulation materials, and composite wood products 🧴 Household Products — Common household products such as air fresheners, fuel and cleaning products emit VOC compounds in the air 💅 Personal Care Products — Formaldehyde is the most common type of VOC. It is found in many products we use daily at home, including nail polish! 🍳 Daily Activities — Some daily activities and habits like cooking, dry cleaning, photocopying, burning wood, and smoking also release VOCs into the air. |
What to Look for When Buying an Air Purifier for VOCs
Whether an air purifier can remove VOCs depends completely on the filter inside. Since VOCs are emitted in a gaseous state, they can easily be absorbed from the air by the right filter. Thus, an air purifier for VOCs is specifically designed to remove these harmful airborne particles and chemicals from the air.
The problem for those looking to buy an air purifier for VOCs is that most units on the market use HEPA or a dual ionizer/HEPA filter and these do very little to remove gases like VOCs from the air.
1. Choose an air purifier with a large amount of activated carbon
Activated carbon is simply carbon that has been oxidized to create millions of ultra-wide pores that can absorb gas molecules effectively. You can mainly remove VOCs with the help of powerful activated carbon filters, as these will trap gasses and vapors in addition to smells associated to smoke, pets and cooking.
The downside to this type of filtration is that you need large amounts of activated carbon to deal with lots of VOCs, as the amount of gasses an activated carbon filter can deal with is directly connected to the quantity of activated charcoal in the filter itself.
That is why you should aim for an air purifier with as much activated carbon as possible.
| Did you know? A study by the University of Reading in England tested and compared different filter technologies showing that adsorption filter technology (like that of activated carbon filters) is the most efficient at removing volatile organic contaminants like formaldehyde, benzene, and ammonia. |
2. Ensure the air purifier’s recommended room size matches the space you want to purify
You should always check the manufacturer’s guidelines related to recommended room size for the unit you’re considering. Still, it is even more important when tackling a severe issue such as VOCs indoors. The air purifier wouldn’t work as effectively as it could if you placed it in a room larger than the size it can handle.
Even though it might feel like a drag, take the time to measure the space where you will be placing the unit to ensure it matches the manufacturer’s recommendation.
3. Don’t fret over smart features
The latest air purifiers usually include an array of smart features to simplify the process on the user’s end. For instance, air purifiers boasting a ‘smart mode’ will automatically turn on and adapt fan speed levels depending on the air quality in the home in real-time.
The reality, however, is that your air purifier will need to run at full speed to remove VOCs from the air. Therefore, this smart feature is not a requirement for this device. You will be the best person to turn the unit on and blast it at full speed for the duration of your stay in the affected room.
4. Consider noise levels if you’re sensitive to sound
Since your device will likely run at full speed 24/7 while dealing with VOCs in the air, you must consider the associated noise level before purchasing it. If you want an air purifier with an acceptable sound level, consider purchasing one with a high CADR to ensure it comes with a powerful fan that runs smoothly at top speeds. It is also worth looking for the unit with the lowest decibels (dB) at the highest fans speed – all this info is in the specs table below the units on this list.
There are quiet air purifiers, but sadly many don’t use a large amount of activated charcoal, so they are not a good fit for removing VOCs.
5. If you’re conscious of your energy bill, pay attention to power consumption levels
As I mentioned above, when dealing with VOCs you will find yourself using our air purifier a full speed for extended periods of time. This means that electricity consumption can become an issue. The cost of electricity is rapidly rising, so being wary of power consumption can pay off in the long run.
When researching, check the air purifier’s power consumption specs before purchasing it. We test energy consumption ourselves and turn the KW figure into yearly cost using the Department of Energy’s appliance energy calculator so pay attention to that figure under the ‘estimated energy consumption’ row of the specs table below the units we’ve shortlisted here.
6. Keep unit costs in mind but also calculate replacement filter costs
These devices are costly, especially the ones that use large amounts of activated carbon. Therefore, ensure that you check the cost of the device and the replacement filter cost. For effectiveness, air purifier filters must be replaced regularly, so ensure your choice fits your budget.
Wrapping Up
Air purifiers aren’t difficult to find, but when you want them to handle volatile organic compounds (VOCs), you must pay extra attention to the filters. HEPA filters are popular but unable to handle such chemicals in the air, so you want to choose an air purifier with a large amount of activated charcoal.
If you can afford it, then our top choice is the IQAir HealthPro Plus, hands down.
