5 Best Air Purifiers for VOCs – More Carbon, Less Toxins!

Breathe in. What did you just inhale? Mostly invisible and often unnoticed, volatile organic compounds (VOCs) are harmful pollutants present in our homes at levels 2 to 5 times higher than outdoors. They lurk in paint, cleaning supplies, and even new furniture, posing potential health risks—ranging from eye irritation to nervous system damage.

One effective way to combat VOCs is by using an air purifier—but not just any air purifier. You need one equipped with the best possible features and filtering technology to adsorb VOCs effectively. The key component is an activated carbon filter (ideally pellet-based), which should be as large as possible. I’ll dive deeper into these features throughout the article.

Before we get into the details, it’s important to remember that high concentrations of VOCs can irritate the eyes, nose, and throat and potentially harm the nervous system and overall health. This is a serious issue that requires immediate action. In addition to using an air purifier, I strongly recommend ventilating your space as much as possible—especially when using household cleaning products, which are a major source of VOCs.

Through rigorous market analysis, extensive testing, and comprehensive reviews of filtration technologies, I’ve created a list of the top 5 air purifiers to help you tackle VOCs effectively.

Additionally, I’ve answered the most frequently asked questions on the subject and recommend that you read the entire article, as you’re likely to find answers to your concerns and definitely learn something new along the way.

Top 5 Air Purifiers For VOCs

I’ve created this list of the best air purifiers for VOCs by carefully balancing price and performance. You’ll find several affordable options that are still highly effective at removing VOCs.

However, my primary focus has been on air purifiers with the highest possible activated carbon content, as this plays a crucial role in adsorbing VOCs. If an air purifier also includes additives like zeolite, that’s a bonus.

Many popular air purifiers feature high-quality HEPA filters, which excel at capturing small airborne particles. However, they often lack effective carbon filters, making them less suitable for VOC removal. This is one reason why air purifiers with larger carbon filters tend to have a higher initial cost.

Winix 5500-2 – Best Budget Option (Approx. 1 lbs of Carbon)

The Winix 5500-2 is one of the best air purifiers we have tested and is frequently among our top three recommendations. It covers rooms of up to 360 sq. ft. (33 m²) with an ACH of 4.8.

What I like about the Winix 5500-2 is its high-quality, highly efficient four-stage filtration technology. Additionally, it offers some advanced features while maintaining an affordable price.

The first stage of filtration is a pre-filter, followed by a True HEPA filter as the second stage. The third stage is an activated carbon filter, and the final stage is the PlasmaWave technology.

The activated carbon filter is the most important to us, as other filters are less effective in removing VOCs. It contains about 1 lb of carbon pellets.

Although the Winix 5500-2 uses an activated carbon filter with a lower carbon concentration than some of the other devices on our list, I believe it does a perfectly solid job, especially for the average household.

I personally used this air purifier when I was painting my house a while ago, and I have to give it a thumbs up because I didn’t smell the paint at all. In addition, I want to highlight that this air purifier not only helps remove VOCs but also improves overall air quality thanks to its high-quality True HEPA filter, which effectively traps other airborne particles.

Keep in mind that the Winix 5500-2 is relatively large, so you’ll need to find a suitable spot for it in your room.

I’ve also recommended the Winix 5500-2 as one of the best air purifiers for smoke removal, further proving its exceptional quality and reliability.

All in all, the Winix 5500-2 is my top recommendation if you’re looking for an affordable air purifier that effectively removes VOCs.

IQAir is a giant in the air purifier market, and the GC MultiGas is a device that boasts perhaps the highest-quality filtration technology available.

Although its high price may be a barrier to purchase, I believe you can’t go wrong with the IQAir GC MultiGas. This air purifier cleans the air at least a shade better than any other device on the list. It is best suited for rooms up to 473 sq. ft. (43.9 m²), where it cleans the air 4.8 times per hour.

The IQAir GC MultiGas is designed for large rooms and offers chemical removal power equivalent to more than 100 gas masks. Its HyperHEPA filter captures particles up to 100 times smaller than those trapped by some traditional filtration systems, effectively removing particles as small as 0.003 microns.

The filtration stages on this air purifier include a GC HyperHEPA H11 pre-filter, a set of GC filter cartridges, and a set of GC post-filters. Frankly speaking, this is one of the most efficient filtration technologies currently available on the market.

The IQAir GC MultiGas contains 12 lbs of carbon of activated carbon, which is more than sufficient to effectively neutralize VOCs.

Without a doubt, this is the best air purifier you can buy to combat VOCs, and I’m sure it will serve you well for years. Additionally, I highly recommend this air purifier for neutralizing cigarette smoke, wildfire smoke, odors, mold, and other extremely harmful pollutants.

The Austin Air HealthMate Jr. is a USA-made air purifier that has been on the market for several decades.

It covers rooms of up to 185 sq. ft. (17 m²), meaning it can clean the air 4.8 times per hour within the recommended room size.

It uses a four-stage filtration system consisting of a Large Particle Pre-filter, a Medium Particle Pre-filter, an Activated Carbon and Zeolite filter, and a True Medical-Grade HEPA filter.

What makes the Austin Air HealthMate Jr. ideal for combating VOCs is its high concentration of carbon inside the filter. It has approximately 6.5 lbs of carbon pellets. However, it’s worth noting that there is also a larger model of the Austin Air, which contains over 15 lbs of carbon pellets—an option I would recommend for those dealing with heavy VOC issues.

Although this air purifier is one of the best for removing VOCs, gases, smoke, and similar pollutants, it performed poorly in our airborne particle removal tests. In a room of 194 sq. ft. (18 m²), it improved air quality by about 86%, which is a lower result compared to some much cheaper air purifiers.

A few other downsides of the Austin Air HealthMate Jr. include its old-fashioned design, lack of advanced features, and simple controls.

Additionally, it consumes too much power for its CADR rating.

Despite these drawbacks, the Austin Air HealthMate Jr. is effective in reducing coughing, wheezing, and sneezing. It is definitely an air purifier I would recommend for VOC removal, primarily due to its excellent combination of carbon and zeolite filters.

Alen FLEX – Best Design & Great Performance (2+ lbs of Carbon)

The Alen FLEX is the most modern air purifier on this list. It’s a stylish device that will complement almost any environment. It covers spaces of up to 300 sq. ft. (28 m²), meaning it will clean the air 4.8 times per hour inside the recommended room size.

How Can an Air Purifier Remove VOCs?

The biggest dilemma is whether air purifiers can remove VOCs from the air at all and whether it is worth buying an air purifier for this purpose. This doubt is correct, especially considering that not every air purifier can remove everything.

VOCs are a very serious problem, and I would never recommend buying air purifiers for this reason. To this end, the device must be up to the task, have the appropriate filtration technology, and be efficient. In fact, the most effective filters for neutralizing VOCs are those that can adsorb VOCs, and such filters are activated carbon filters.

Filtration Technologies and VOC Efficiency

HEPA Filters

Air purifiers used for household, non-industrial, and most accessible to almost every ordinary user usually have some kind of HEPA filter as a filter layer. HEPA filters are excellent, especially True HEPA filters, which remove 99.97% of airborne particles down to 0.3 microns in size.

These filters are great for catching small, and large particles such as dust, pollen, pet hair, and similar pollution but are completely ineffective for VOCs, as these particles are almost 1000 times smaller than the particles that a HEPA filter can catch.

A HEPA filter is basically made up of paper or fibers that do not allow particles of a certain size to pass through and so clean the air. In fact, there is nothing in this type of filter that traps VOCs.

Ionizer

Ionizing filtration technology is also very common in many air purifiers. However, this technology is also not effective in removing VOCs.

Basically, the ionizer produces negative ions that bind to heavier particles in the air and then drop them to the ground, and then in combination with some other filtration technologies, neutralize these particles. This means that the ionizer does not destroy particles at all, nor does it bind to VOCs, so this technology is not effective enough even for VOCs.

UV-C Lights

UV-C light is perhaps the most effective way of removing VOCs of all the methods mentioned so far. This is because UV-C light does not adsorb or trap but destroys particles, namely mold, mites, VOCs, and similar stuff. This means that, in theory, UV-C light can destroy VOCs. In addition, this filtration technology is known to destroy some bacteria and viruses.

However, there are two problems with UV-C lights in air purifiers:

1. The first problem is that UV-C lights in air purifiers are mostly not powerful enough, so they cannot destroy particles effectively enough.
2. The second problem is that the air does not stay in the UV-C light for long enough, so it simply does not have time to destroy harmful particles.

Overall, the idea behind UV-C filtration technology is excellent, but I think that more innovation is needed in this area to perfect the technology.

Activated Carbon Filter

As I have already hinted in the previous part of this article, the activated carbon filter is the most effective method for removing VOCs. The point with this filter is quite clear, the bigger/heavier the activated carbon filter, the more effective it will be and the easier it will fight VOCs. The activated carbon filter removes both reactive and non-reactive VOCs.

The activated carbon filter works on the principle of adsorption, which is why it is so effective at removing these pollutants, and this filter also removes odors, neutralizes almost all unpleasant smells, and contributes in many ways to keeping the air quality in your home at a high level. However, it is important to bear in mind that even though this filter cannot adsorb all pollutants from the air, it is quite effective enough for domestic situations.

VOCs are a large category, and many gasses, such as benzene and formaldehyde, fall into this category. This basically means that an air purifier with an activated carbon filter will neutralize formaldehyde.

Things to Consider When Choosing an Air Purifier for VOCs

It’s no bad thing to confirm the most important fact, which is that an air purifier that effectively combats VOCs must have an activated carbon filter built in. In addition, there are a few general items that you can look out for when buying or choosing your preferred air purifier.

Filter type: since HEPA filters are not effective in combating VOCs, the air purifier must have an activated carbon filter.

Price: Price is a decisive factor in everything and can have a big influence on the choice. However, this does not always mean that if an air purifier is expensive, it is also good. That’s why I review as many different air purifiers as possible from different manufacturers and in different price ranges, all so that I can give you the best possible suggestions.

Noise level: this is a device you are likely to have on all the time, which means you also need to think about the volume it produces at different speeds. My suggestion is to always choose an air purifier that has as many different speeds as possible, as this will make it easier for you to adjust the mode of operation and help you find the fan speed that suits you best.

Room coverage: It is pointless to buy a weak air purifier because it will not be able to do its job properly or to buy an air purifier that is too strong and will use more resources than necessary. Therefore, before you buy, you should research exactly how large rooms the machine covers and whether it is just the right power you need.

Operating costs: The price of electricity is rising, and air purifiers are electrical appliances, so you need to pay attention to power consumption before choosing an air purifier. That’s also why I do a detailed analysis of the power consumption and profitability of the air purifier at each review.

Filter cost: In addition to the cost of electricity, there is also the cost of replacement filters, which in some air purifiers last more than one year, so it would be a good idea to include this cost in the annual maintenance costs.
