Buying Guide

The air quality in our homes can change from day to day and season to season. Apart from dust and pollen, there are also those VOCs, which you can’t see, but are still in the air you breathe. The best way to get rid of all those unwanted particles in the air is to use a quality air purifier. The air is pulled into the unit, and all those nasty extras are filtered out, leaving pure, clean air behind. Of course, not all models have identical features, so check out the sections below for everything these units may have to offer.

What are VOCs and why to get rid of them?

8 Best Air Purifiers for Getting Rid of VOCs and FormaldehydeVOCs, or volatile organic compounds, are the gases that are emitted from a wide variety of products that you buy for your home. These products include things like paint, cleaners, fuels, varnishes, cosmetics, and much more. Though you may notice the VOCs more from liquid products, they exist in solids as well, like craft materials, building materials, and even some furnishings, such as mattresses and couches.

Though the VOCs released by the products you buy will dissipate over time, there are some adverse reactions to having them linger in your home. These can include symptoms like fatigue, nausea, dizziness, headache, nose and throat discomfort, skin reactions, and conjunctival irritation. Long-term exposure can lead to some more serious issues, like damage to your kidney, liver, or central nervous system and loss of coordination. There is also some evidence that some VOCs can cause cancer in animals, which puts any pets in your home at risk.

To avoid any of these symptoms, from the mild to the severe, clearing the VOCs out of the air is a must. When using products that contain VOCs, do so with your windows open to circulate the air and release them from your home. Using an air purifier, like the Dyson HP01 or any of the other models in our reviews, can also help eliminate them from the air.

Features to consider when choosing an air purifier for VOCs

When choosing a new air purifier for VOCs, there are a few features to consider. This will ensure that you’re getting the best model for the issues you’re dealing with and the size of your home.

Coverage area

8 Best Air Purifiers for Getting Rid of VOCs and FormaldehydeThe coverage area of the units in our reviews refers to the size of the room that it works best in. Coverage areas aren’t determined by the size of the machine or the type of filters they use. Instead, the coverage area is chosen concerning the CADR, or the Clean Air Delivery Rate. The CADR rating tells you how effective the air purifiers filters are for reducing smoke, dust, and pollen in the air. It is measured in cubic feet, using particles that range from 0.10 to 11 microns. The higher the value of the CADR, the quicker the unit can filter the air inside a room.

Unfortunately, the CADR rate isn’t always included in the list of features when you’re looking at air purifiers, though it may be listed in the user manual inside the box. Instead, the coverage area is displayed. The higher the coverage area of the model you choose, the quicker it circulates the air through the air purifier, which means it has a higher CADR rate.

When choosing a new model, make sure the coverage area is one of the first features you look at. A small coverage area, like the Oreck AirVantage Plus, is great for small bedrooms or home offices, though they won’t work well in a large open living area. This is because they can`t circulate the air in such huge spaces. If you’re trying to circulate the air in a large office space or an entire open-concept home, a model like the Alen BreatheSmart 75i, with its 1,300 sq. ft. coverage area, is a better option. Larger coverage areas can handle smaller rooms but smaller ones don’t work well in larger ones.

Filtration system

8 Best Air Purifiers for Getting Rid of VOCs and FormaldehydeThe filtration system is another important feature to look at when choosing a new air purifier, especially when looking for one that filters VOCs out of the air. All of the models in our reviews include a HEPA filter, which removes particles out of the air that are 0.3 microns or larger from the air you’re breathing. The downside is that those VOCs are smaller than 0.3 microns, so can’t be removed by a HEPA filter on its own.

That’s why a few of the models, like the Dyson HP01, combine activated charcoal filters with their HEPA filters since this extra layer catches those VOCs and traps them. Other models use a separate activated charcoal filter, like the carbon pre-filter in the Honeywell HPA300. This removes the VOCs from the air as it passes through the pre-filter and the HEPA filter takes care of all of those other particles, like the pollen, dust, mold spores, and much more.

There are also some other filters added to the units in our reviews, which can filter out even more than the VOCs and larger particles. Some models can even help to remove bacteria and viruses from the air. This helps to prevent any illnesses in your home from spreading by eliminating the germs from colds and flus that your family members may be dealing with. The more filters there are in the machine, the more effective they are at cleaning the air in your home of any of those unwanted particles.

Speeds

Another important feature to look for is the fan speeds on the air purifiers. Most models have 3 or 4 speeds to choose from, so you can turn it up on high to clear out the air when it’s particularly bad and down to medium or low to maintain the air quality. Some models go much higher than this for air speeds, like the Dyson HP01, which has 10 speeds, so you have a wide variety of speed options to choose from.

There are also a few other speed options to consider before picking a new air purifier. Some models have a Turbo mode, which is an extremely high fan speed that is used to quickly circulate the air and clear out any unwanted particles and odors. Many of the units in our reviews also include an Auto Mode, which adjusts the fan speeds automatically as the air quality in your home changes, turning it up when needed and back down again when the air is clean again. This helps maintain the air quality without any action on your part.

Timer

8 Best Air Purifiers for Getting Rid of VOCs and FormaldehydeA timer is another great feature you may want in a new air purifier for VOCs. This feature allows you to choose a specific time that you want the air purifier to run. When the timer runs out, the unit turns off unless you are there to add more time or turn it on without setting the timer. Some models, like the Honeywell HPA300, have set timer options of 2, 4, and 8 hours to choose from. Units like the Oreck AirVantage Plus let you pick the time, up to 8 hours, that you want the unit to run. This allows you to set it while you’re at work or for a certain amount of time during the day without leaving it running continuously when it may not always be needed.

Noise level

No matter how well your air purifier works, you aren’t going to want to use it very often if it is too loud. A noisy machine will drown out conversations, the television or stereo, and make it impossible to sleep. Luckily, the manufacturers of these units have taken this into account and created a wide variety of models that run much quieter than the old models. The lowest settings on these machines are almost inaudible in most cases, though the highest or Turbo settings may be a bit noisier. They still shouldn’t make it difficult to talk to others in the room but you may not want to sleep with the air purifier on the highest settings.

A lot of the units in our reviews have also included a Night Mode, which runs the unit on a lower setting to make it easier to sleep with one of these units in your bedroom. As a bonus, this mode usually dims the lights as well as running quiet, making it even less disturbing to run it at night, even when next to the lightest sleeper in the house.

Air quality detector

8 Best Air Purifiers for Getting Rid of VOCs and FormaldehydeUnits like the Hathaspace HSP001 include an air quality sensor with their other features. Air purifiers with this feature can actually monitor the air quality in your home in real time, so you are always aware of any issues that may need to be dealt with. This way, you can turn the fan speed up when the air quality is bad and down again when the unit has done its job and removed all of the harmful and unwanted particles from the air.

The Auto Mode included with some units also works well with the air quality sensor. When the air quality is low, the Auto Mode automatically switches to a higher fan speed to eliminate those nasty particles that are contaminating the air. When the sensor shows the air quality is good, the Auto mode lowers the speed to maintain that level of quality.

Wi-Fi capability

Though it isn’t a common feature on air purifiers for VOCs, a unit with Wi-Fi capability is handy to have. Along with the unit, there is an app that you can download onto a Smartphone or tablet, which you can use to adjust the fan speeds, modes, and timers the same way you would with a remote control. As well as giving you full control over the unit from across the room or another room of your home, you can monitor the air quality and adjust the settings when at work, out to dinner, or visiting friends. You can also turn the unit on or change the speeds when you’re on your way home to ensure the air quality is perfect when you walk in the door rather than leaving the unit running all day when no one’s home.

Dimensions and weight

The dimensions of the unit may not seem important until you try to fit the unit you’ve purchased into the room you need it for. The bigger it is, the more space it’s going to take up, especially when you consider that you need to keep it a few feet away from any walls and furniture to ensure the proper airflow through the machine. If you’re concerned about space, measure the area you have available and buy a unit that fits in that space without sacrificing the features you want.

The weight will only be an issue if you’re planning on moving your air purifier from room to room. The heavier it is, the harder it will be to carry. Some of them, like the Blueair Classic 480i, do have wheels to make it easier to move around for an easier process. Lighter units are easier to move when needed, with or without the wheels.

Warranty

Though you expect the products you buy to last for a while, this isn’t always the case. That’s why you need a good warranty to cover you in case the air purifier you buy isn’t working as it’s supposed to. Though a 1 or 2-year limited warranty is fine, many of the models go higher, like the 5-year limited warranty on the NuWave OxyPure Large Area Smart Air Purifier. Some models also include a lifetime warranty, though there may some fine print involved with this. The Alen BreatheSmart 75i has a lifetime warranty, though it is only valid if you sign up for a replacement filter subscription, so be sure to check the fine print before buying one.

FAQ

Most of the filters in our reviews will need to be changed about once each year. This can vary depending on the air quality of the area you live in. For instance, more polluted areas or those living in areas near wildfires may be dealing with lower air quality at times, so the filters may need to be changed more frequently.

Yes, an air purifier can help with allergies. They help remove those allergens from the air, including pollen, dust mites, dust, mold spores, smoke, and much more. The air in your home will then be purer and cleaner, reducing your allergic reactions and allowing you to breathe easier.

Yes, an air purifier can help to fight the transmission of viruses, including Covid-19, SARS, and other recent viruses. The air purifier needs to have a HEPA filter as part of its filtrations system to trap these viruses, though. All of the models in our reviews include this type of filter, so any of them can be purchased to help combat virus transmission.

Our Verdict

With so many different air purifiers for VOCs, formaldehyde, and other harmful pollutants on the market, it can be difficult to choose the perfect model. Though all the units in our reviews are great options, we do have a few top choices.

Our favorite is the Dyson HP01, which is an air purifier, heater, and fan all in 1 great unit. This powerful machine has a combined activated charcoal and HEPA filter, 10 speeds, a sleep timer, an auto-shutoff for tipping, 360-degree oscillation, and dual heat zones.

The AIRDOCTOR 4-in-1 Air Purifier has 3 filters, including a washable pre-filter, plus an ionizer. It also includes a huge 900 sq. ft. coverage area, built-in timer, simple controls, a WhisperJet fan, and dimmable lights for using it at night.

The Oreck AirVantage Plus is a great budget-friendly model, with 3 speeds and Silence Technology on the low setting. This small room model also includes simple controls, a remote control, a timer, and a filter indicator.
