How We Decided
With hundreds of air purifier brands and models to choose from, it can be hard to differentiate which is best. In making our selection, we took many factors into account, from customer reviews and features offered, to pricing and more.
We also considered how widely available each model was at easily-accessible retailers when putting together our picks.
The following criteria had the biggest impact on our decision.
The best way to gauge the effectiveness of a product outside of rigorous testing is to look at the opinions of those who know best - customers and users of the product.
We took customer reviews into consideration when pulling together our list of the best air purifiers, and chose those with the best and most relevant customer feedback.
We also looked at which came highly-recommended by experts in the home and tech spaces.
While air purifiers are, for the most part, a pretty sizable investment, a large purchase can be better justified if the features and effectiveness set it apart from more affordable competitors.
We chose air purifiers that we felt were a fair balance between price and highly-coveted features.
With offerings varying greatly from one air purifier to the next, we chose the ones that had the best features specific to their category, from the best to tackle pet dander to the best for those with allergies.
How Do Air Purifiers Work?
Air purifiers are designed to both remove and sanitize particles from the air. This typically works by moving air through a filter - or layers of filters - that capture damaging particles like dust, pollen, or pet dander. The clean air is then sent back into the living space.
However, some air purifiers work differently and it's important know how they each works before you decided which one is right for your needs.
What Are the Different Types of Air Purifiers?
There are a few different ways the air in a room can be purified, particularly when it comes to what kind of contaminants are actually being removed from the air.
HEPA Filter Air Purifiers
HEPA filters are the gold standard when it comes to air purification. Air is pushed through the filter, removing pathogens, allergens, dust, and other micro-particles, trapping them in the filter.
Finally, the air is pushed back into the room while new air is drawn into the purifier.
This is the usual go-to for people who want a relative particle-free and pollution-free space.
HEPA filters can also be used in central and other HVAC systems.
Is a True HEPA Filter Important?
HEPA stands for High-Efficiency Particulate Arresting, and it is the highest standard for physical air filtration.
In order to be considered a True HEPA filter, it must be able to block 99.97% of all microscopic particles as small as 0.3 microns in size - the size at which a particle can be to get into your lungs.
Can You Wash HEPA Filters for Air Purifiers?
No. Unless indicated by the manufacturer that you can wash the filter, in most cases you will not be able to wash them and reuse them.
This is because most HEPA filters have nuanced and functional ridges and contours that may be flattened or distorted in the cleaning process.
If this happens, the efficacy of the filter is greatly reduced and defeats the purpose of even having an air purifier.
Instead, always make sure you have a few refills on hand or subscribe to a filter delivery service so you're always prepared.
Carbon Filter Air Purifiers
These air purifiers work similarly to HEPA filter air purifiers except they use filters filled with activated charcoal. Carbon filters are ideal for removing odors, smells, toxic fumes, or gases but don't work to remove allergens or small harmful particles in the air.
For further purification, an additional HEPA filter is needed in conjunction with carbon filters.
Carbon filters are great for use in spaces with might leach chemical fumes such as from carpeting, high VOC paints or finishes, or a room near the garage (where you might smell gas)
If you do a lot of cooking carbon filter air purifiers could be a good addition to your kitchen.
It's important to note that carbon filters can remove gases and fumes but other types of filters and purifiers cannot.
UV Light Air Purifiers
UV Light air purifies, like carbon air purifiers, use the same mechanism as the HEPA purifiers of drawing air and pushing it back out to clean the air.
Instead of pushing the air through a filter, the air is instead exposed to UV light which kill harmful microorganisms in the air.
This type of purifier is used to disinfect and clear the room of any potential pathogens and germs.
It is possible to find air purifiers that offer both HEPA filtration along with UV light disinfection.
However,it is important that you select a UV air purifier that uses a "safe" wavelength. If not, you are at risk of creating ozone with UV light because at certain wavelengths, oxygen molecules can split and, in turn, reform as ozone.
Ozone is a harmful gas in your home.
Ionic Air Purifiers
There are two different types of ionic air purifiers--ionizers and electrostatic precipitators (also referred to as ESPs).
Ionizers dispense charged particles (usually negatively charged) into a room. When these charged particles come in contact with other airborne particles, they attach themselves and they basically get "pinned" to surfaces in that room, making them easy to wipe away.
ESPs work similarly but with positively charged particles. Another big difference is that instead of attaching airborne pollutants to the room's surfaces, they instead are caught on a plate within the purifier, making clean up much easier.
Generally, ionic air purifiers aren't recommended as they don't do as good of a job of removing pollutants as HEPA filter air purifiers, and furthermore, they create ozone when particles are discharged into the air.
