What to Consider When Buying an Air Purifier

When it’s time to pick a model for your home from our Best Whole House Air Purifier list, here are the factors to keep in mind.

Size and Coverage

Air purifiers are made to work in rooms and houses or apartments of different sizes. To make sure you’re getting one that will be effective, check the square footage that the unit can cover. All of the models we’ve covered list the maximum square footage in the product description. Be sure that any model you consider is sufficient to cover your house or the space that you’re looking to purify. Keep in mind that you can use multiple purifiers in different parts of your house if necessary.

HEPA Filters

The best air purifiers on the market will use a high-efficiency particulate air (HEPA) filter. These filters are designed to remove 99.97 percent of particles that are 0.3 microns or larger from the air that passes through them. That includes things like dust, pollen, mold spores, and pet dander. If you suffer from allergies or asthma, it’s important to make sure that the unit you choose has a HEPA filter.

Activated Carbon Filters

Some models also include activated carbon filters. These filters are effective at removing smoke, chemicals, and other odors from the air. If you have pets or smokers in your home, you may want to consider an air purifier with an activated carbon filter.

Asthma & Allergy Friendly

If you or someone in your house suffers from asthma or allergies, you’ll want to verify that an air purifier has been certified as “Asthma & Allergy Friendly“.  This certification is given by the Asthma and Allergy Foundation of America (AAFA) and it means that a unit has been tested and proven to reduce asthma and allergy symptoms. While models that have not been certified may be able to help reduce the symptoms of asthma and allergies, the certification certainly helps to provide more confidence.

Ozone Generators

Some air purifiers use ionizers or ozone generators to help clean the air in your home. These devices emit negative ions or ozone into the air which then attach to particles like dust, pollen, smoke, and mold spores. This makes them heavier so they can settle out of the air or be caught by the filter. While these devices can be effective at reducing allergens, they can also create harmful ozone gas if used improperly. We recommend avoiding these types of air purifiers.

Clean Air Delivery Rate (CADR)

The CADR is a rating that tells you how well an air purifier can remove specific types of particles from the air. The higher the CADR, the better the unit is at removing that type of particle. 

Energy Efficiency

While running an air purifier will help to improve the air quality in your home, it will also increase your energy bill. To make sure you’re not spending more than necessary, look for an energy-efficient model. These units use less electricity to operate and can help to keep your energy costs down.


As with any purchase, you’ll want to consider the price when selecting an air purifier for your home. But be sure to focus on value rather than just the bottom line. A more expensive unit may have features that are worth the extra cost. Conversely, a less expensive model may not have the same quality construction or features as a more costly unit.

Do I need an air purifier if I have central air?
