Our Review

The NuWave OxyPure is a durable and reliable unit that you can trust to handle the high VOC concentration in your home effectively and successfully.

Formaldehyde Air Purifiers: Buying Guide

What Is a Formaldehyde Air Purifier – and How Does It Work?

formaldehyde removal

A formaldehyde air purifier looks just like a regular air purifier - the difference is that it contains a deep-bed activated carbon filter.

Not every air purifier can remove formaldehyde. In fact, most models available online don’t even have the filters to remove it. They typically rely on HEPA filters alone to clean the air.

An air purifier for formaldehyde contains large quantities of activated carbon. It is obtained from natural substances such as charcoal or coconut shells, which is then treated with oxygen to make it extremely porous.

When gases, odor molecules, and VOCs pass through the porous surface, they are adsorbed. In simple words, a chemical reaction occurs between the carbon surface and VOCs like formaldehyde that binds them to the activated carbon and traps them inside.

The higher the carbon content in the filter, the more formaldehyde it will hold.

Why Buy a Formaldehyde Air Purifier?

Formaldehyde is a type of VOC commonly found in many products around your home.

Familiar with the off-gassing smell of new furniture?

Yep, that’s formaldehyde.

It is considered volatile because it emits a gas at room temperature. The higher the temperature, the more gas it emits, which can be hazardous for your health. That’s why a good formaldehyde-removing air purifier becomes a necessity.

Here is why you should purchase one of these:

Remove Dangerous VOCs

formaldehyde air filter

A formaldehyde air purifier not only reduces formaldehyde concentration in your home but also removes other dangerous VOCs that pose a health risk.

Compounds like benzene, xylene, and toluene can make you seriously ill. However, none of these is as dangerous as formaldehyde, as it can cause serious health issues like ulcers and cancers.

Allow You to Enjoy Your Home Better

If you have just moved to a newly built house with all new furnishings and items, chances are it strongly smells of formaldehyde and other gaseous VOCs. These cause lingering smells and itchy eyes that prevent you from enjoying your new home to its fullest.

Having an air purifier to remove VOCs easily resolves these issues, allowing you to have a better experience.

Eliminate Lingering Odors

New paint or furniture always brings with it some lingering smells. These smells can quickly trigger allergic reactions like runny eyes, sneezing, or runny nose if you are chemical-sensitive. You should buy an air purifier for VOCs and formaldehyde to tackle these lingering odors.

It Enables You to Breathe More Easily

Breathing in air full of VOCs like formaldehyde is not just difficult- it is downright dangerous. Knowing that risk, you should immediately get a good VOC-removing air purifier to stop related health issues from arising.

What to Look for in a Formaldehyde Air Purifier

Since formaldehyde in homes is mostly in gaseous form, you need a purifier that can remove gases in substantial quantities. Many home air purifiers with particle and activated carbon filters are not too effective at eliminating formaldehyde and VOCs.

Less expensive plain carbon filters can surely hold many chemicals well but cannot effectively retain formaldehyde for a long time.

Here are some features that make an air purifier great for removing VOCs like formaldehyde:

Oxidant Capability

While having a HEPA filter and an activated carbon filter is necessary for a cleaner home environment, if you want to eliminate formaldehyde from your home, you should only consider products with oxidant chemicals.

Look for models with chemicals such as potassium permanganate, alumina, and potassium iodide added within the different filtration stages.


The size of the air purifier is also an important consideration when purchasing a new formaldehyde air filter.

Smaller units, although portable, generally don’t have a high area coverage or air cleaning capacity. And their low carbon content might not be enough to counter formaldehyde in your home.

Bigger air purifiers with deeper carbon beds are more effective at trapping formaldehyde and other VOCs.

If your home is large or you plan to use the formaldehyde-removing air purifier in a big room, you should steer clear of smaller units because they won’t even purify the air in one room properly; let alone address your formaldehyde odor problem.

Noise levels

Some people are more sensitive to noises than others. That’s why considering the device’s noise level is crucial for your comfort.

Most manufacturers clearly list the maximum and minimum decibels of noise their product makes in the list of specifications.

You should make sure it is bearable at the highest speed. And at lower speeds, it should be low enough for maximum comfort, especially at nights when the sound could disrupt your sleep.

Filter Type

formaldehyde air filter

Although pre-filters, PECO, Ionizer, UV-light, and HEPA filters all play a role in improving indoor air quality, the most important filter for a chemical air purifier is an activated carbon filter with high carbon content. 

A thin sheet of carbon pre-filter won’t effectively capture formaldehyde. Look for a model with a thick carbon filter.

You should also check the type of absorption media added to the carbon filter to improve its performance. Additives like alumina, zeolite pellet, potassium permanganate, potassium, and coal also increase the filter’s effectiveness against smoke particles.

Weight & Portability

The weight of an air purifier is important to consider if you plan on moving the device from one room to another for better formaldehyde odor removal.

Heavier devices are certainly pretty difficult to carry around, which is why a lighter one is a more suitable option.

For increased portability, some devices have casters and wheels to transport them easily. Similarly, some units have handles for easy carrying and holding.

Removal Rate

Since formaldehyde is a stubborn chemical to remove from the air, you should carefully check the purifier’s CADR rating for smoke removal to understand whether it is effective at formaldehyde removal.

A good VOCs air purifier has a strong smoke CADR between 150 and 200 cfm. Any lower, and it won’t be able to remove formaldehyde from a large living room, garage, bedroom, or basement.

An air purifier that can deliver at least 2 air changes per hour is also worth considering in this regard.

Coverage Area

formaldehyde air purifier

Each purifier has a different coverage area.

Since you want maximum removal of both VOCs and formaldehyde, you should get an appropriately sized unit. This means you should look into getting a device that either meets or exceeds the square footage of the room you will use it in.

If you plan to use the device all around your house, you should get a unit whose area coverage matches the square footage of the largest room in your home. That way, you can easily use it everywhere.


With regular use, electronic devices tend to develop issues. And a warranty comes in handy if you want defective components replaced or if you want your unit repaired.

Since you will run your new formaldehyde air purifier initially for long periods, it’s better to get a unit with longer warranty coverage. That way, even if the device starts malfunctioning, you can have it looked at without any worries.

Pros and Cons of Using an Air Purifier for Formaldehyde & VOCs Removal

The principal function of an anti-formaldehyde air purifier is to trap the gaseous molecules so they cannot recirculate into the room.

And while they have other benefits as well, they don’t come without their drawbacks.

To make sure you make an informed choice, here are some important pros and cons that you should know:


Effectively capture VOCs and formaldehyde, and stop them from making their way back into the room

Protect you from serious health issues like respiratory complaints and damage to internal organs by reducing the chances of formaldehyde and VOCs inhalation.

Use multiple-stage filtration to improve overall air quality

Apt at removing lingering odors from your home


More expensive than traditional air purifiers

Replacement filters tend to be more costly

Frequently Asked Questions

How long should an air purifier run for effective VOC and formaldehyde removal?

This greatly depends upon the VOC and formaldehyde concentration in your home. If you just moved into a new house with new furnishings, you need proper ventilation and air purification to remove the VOCs off-gassing into the air.

The air purifier may need to run round the clock for a few days before the smell of formaldehyde goes away completely.

Is it possible to check and detect the levels of VOCs inside my home or office?

It is possible to check and detect VOC levels inside your home or office in real-time by using a handheld PID (Photo Ionizing Device) tool. These devices use ultraviolet light to break down the VOC molecules into negative and positive ions to identify them.

You can use this device to approximate different VOCs like benzene, formaldehyde, and even methylene chloride.

How frequently should I change the filters in my air purifier?

All manufacturers list the duration of the filter for each device. You can check the manufacturer’s listing to figure out when you should change the filters. Some units conveniently come with a filter change indicator light that turns on when the filters are clogged and need to be replaced.

How long do air purifiers for VOC removal last?

The average lifespan of an air purifier for VOC removal is 3 to 5 years. However, if you take good care of it by cleaning and maintaining it at regular intervals, you can expect it to last up to a decade.

Final Verdict: What Is the Best Formaldehyde Air Purifier Sold Today?

VOCs like formaldehyde can cause serious health problems if inhaled in dangerous quantities. Using a good VOC-removing air purifier is the best way to eliminate them from your home.

And the best one, in our opinion, is the NuWave OxyPure air purifier. It boasts 5-stage filtration with high carbon content to absorb VOCs.

Bissell Air220 Smart Air Purifier is also a great choice. It has a good smoke CADR score and features an air quality sensor.

But if you want something smarter with lots of impressive specs and unique features, go for the Levoit LV-PUR131, and you won’t be disappointed!
