What are the key features that stand out in air purifiers for VOCs and formaldehyde that make them different from other air purifiers? One of the most important features is the filtration method. The two proven options for removing VOCs or formaldehyde are a carbon-activated filter and PECO technology.
Next, you’ll want to confirm that your air purifier has a VOC sensor. This ensures that your appliance is continuously monitoring the air quality and if those pollutants are detected, the air purifier will adjust its operation to remove the contaminants from the air. Of course, other concerns include the CADR rating, noise output, and if there are remote controls or an app versus having to manage settings through the control panel on the device. Keep reading our buying guide for choosing the best air purifiers for VOCs and formaldehyde to learn more.

An air purifier for VOCs and formaldehyde is a special type of air purifier specifically designed to remove harmful chemicals from the air. Volatile organic compounds (VOCs) are usually in the form of vapors and gas and can be released from a wide array of everyday products that people use in their households. This can include air fresheners, cleaning products, carpeting, bedding, furniture, and more obvious items like paints or varnish. It’s also helpful if you’re looking for the best air purifiers for odors because they can help eliminate strong chemical smells.
Formaldehyde is one of the most common types of VOCs and it is also found in a wide array of products commonly found in the home including nail polish, MDF furniture, glues, and even insulation materials. VOCs are often present in higher concentrations indoors than outside because these household items are “off-gas” as time passes.
When present over 0.1 parts per million (ppm), VOCs can cause adverse reactions in some people including burning sensations in the eyes, throat, and nose, or even coughing, wheezing, and nausea. Because of these health concerns, a good air purifier designed to remove VOCs from the air can help minimize the risk of breathing in those harmful chemicals.
The main difference between an air purifier designed to remove VOCs and other air purifiers, such as the finest photocatalytic oxidation air purifiers, is the filtration technology. Just like any other product category, not all air purifiers are effective at performing certain tasks. In particular, there are only two proven filtration methods that can effectively remove these harmful chemicals from the air: activated carbon filters and PECO or photoelectrochemical oxidation technology.
It’s important to note that activated carbon filters are a common option for air purifiers in general. But the distinction between a model designed to effectively remove VOCs and one that can’t is the amount of carbon present in the filter and the thickness of the filter material. Understanding this point is essential as you’ll need to consider the filter quality if removing VOCs is a priority. The best air purifier for dust should have a True HEPA filter, specifically designed to remove dust.
Depending on the filtration technology in your air purifier, there are two ways that these appliances remove VOCs from the air. If you opt for an activated carbon filter, you’ll again want to ensure that there’s enough carbon present in the filter and that the material is thick enough to create an effective barrier that traps chemical vapors and gases.
Typically, you’ll want an air purifier with many pounds of activated carbon. Activated carbon is simply carbon that has been treated with oxygen to create millions of pores. This increases the surface area of the carbon, which allows the material to better absorb chemicals and gases.
Carbon filters by default rely on a passive technology where the air must pass over the filter for chemicals to be removed from it. Another concern with this type of air purifier is that over time, the filter can become so saturated that it’s not working as effectively as it should. In some cases, there’s the risk of previously trapped VOCs being released back into the air.
The alternate technology is PECO. This method is specifically designed for VOCs. While it’s proprietary to just one air purifier brand — Molekule — this filtration process works at the molecular level to not just trap chemicals and gas vapors but to destroy them.
In contrast, activated carbon filters simply trap particles to the filter surface. However, if you’re shopping on a budget, models that rely on activated carbon filters are significantly cheaper than Molekule air purifiers.
It makes sense that you would want your home to have healthy air quality. This is especially true when you realize that everyday items in your home — including your mattresses, couch cushions, or even household cleaning supplies — can all unintentionally work together to create unhealthy environments.
You Have a Respiratory Condition: Without a doubt, if you suffer from any respiratory condition that can be easily triggered by irritants in the air, an air purifier that’s rated to filter out VOCs is a smart choice.
You’ve Recently Remodeled or Redecorated Your Home: Off-gassing is a real thing and is commonly associated with that “new chemical smell” you experience when you buy a new mattress or furniture set or even have your home repainted. If you’re remodeling your home or upgrading existing furniture and don’t want to deal with the literal headache associated with these scenarios, get an air purifier for VOCs.
You’re Concerned About Air Quality: Even if you don’t have a respiratory condition or haven’t recently remodeled your home, maybe you’re just concerned about the air you breathe. While it may not be necessary to have a VOC-filtering air purifier in your home, there’s nothing wrong with erring on the side of caution.
You’re Not Specific About Quality: Activated carbon filter-based air purifiers can be hit or miss if you don’t pick a model with enough carbon present in the filter to effectively clean the air. If you’re not going to pay attention to that key feature, this product category isn’t for you.
You Won’t Consistently Use It: Air purifiers are intended to be used 24 hours a day, 365 days a year. There’s no point in buying these products if you’re only going to use them occasionally.
You Don’t Want to Deal with the Upkeep: The one drawback with any air purifier is that it’s not a “one and done” type of product. Every few months you’re going to need to replace the filter. Along with the time commitment is the associated cost of having to buy new filters throughout the year.
This is more about how frequently the filters need to be changed versus how long the actual appliance will last. Typically, carbon-based filters need to be changed more frequently — anywhere from three to six months. However, carbon filters tend to be cheaper and are usually no more than $50 per filter.
With PECO-based air purifiers, you’ll need to replace the primary filter every six months and the pre-filter every three months. However, because it’s a proprietary technology that’s exclusive to the brand Molekule, their filters are more expensive and range between $80 to $150. These timelines are based on the idea that you’re running the air purifier all day, continuously.
In many ways, shopping for an air purifier that can remove VOCs from the air isn’t too different from shopping for a regular air purifier. Many of the criteria between the two versions are similar, but you will need to pay more attention to the filter quality if VOC removal is a priority for you.
Especially if you decide to buy an air purifier that relies on activated carbon filtration, you need to pay attention to exactly how much activated carbon is in the filter. Experts agree that you’ll need several pounds of activated carbon to effectively remove VOCs. And just as important, the primary filter needs to be very thick.
While you shouldn’t be entirely motivated by budget, the reality is that air purifiers represent an ongoing cost. Beyond the initial investment into the appliance, you also need to factor in periodically replacing the filters.
With activated carbon filters, these should be replaced every three to six months and can cost up to $50. PECO technology is significantly more expensive both in upfront costs for buying the unit and in replacing the filters every six months.
CADR is short for clean air delivery rate and it’s used to determine how much air an air purifier can effectively move after cleaning. Larger CADR scores mean that the appliance can work properly in a larger room. You want to ensure that you pick an air purifier with a CADR score that’s compatible with the size of your room.
Picking a unit with a score lower than needed means that you aren’t cleaning the air effectively. It’s always better to err on the side of caution and get an appliance with a higher CADR than you need — especially if you prefer quiet operation, which is what you’ll find with the high-end quiet air purifiers.
Most air purifiers feature a quiet operation mode. But there are going to be times when it needs to cycle into a higher setting. Or, you might be very sensitive to sounds. Always consider the decibel rating as usually anything around 50 decibels is considered a good benchmark for quiet operation.
There’s nothing more frustrating than fighting to understand how to operate an appliance. Beyond easy operation, you’ll also want to think about whether there’s a remote control or associated app included with your pick. A remote control ensures that you can make adjustments from across the room. And if an app is available, you might even be able to control your air purifier even when you’re not home.
