This post has been updated to include additional considerations when purchasing an air purifier for mold and to confirm current prices and availabiltiy for recommended products.

Mold can cause severe problems for your health and your home. Finding an air purifier that will effectively kill and get rid of mold spores is an essential first step to clearing the air in your home and making it safer for you and your family.

There are certain things you need to look for in a quality air purifier. HEPA filters are a must. Mold spores can’t live or reproduce without moisture, so they die inside the HEPA filter because it is a dry, sterile environment. A true HEPA filter is tested to meet the U.S. Department of Energy standards,  trapping 99.97% of particles that are .3 microns or larger. (Mold spores range from 3-100 microns.) 

HEPA air purifiers that incorporate silver ion filter technology give added protection since they help get rid of mold spores and bacteria more effectively. HEPA air purifiers with carbon filters remove the odor that mold can cause. HEPA filters also need to be checked regularly to ensure the filter is clean and should be replaced at least once a year. Please refer to the specific filter replacement guide in your unit.

Before you buy, you’ll want to consider the square footage the air purifier needs to cover. Purifiers are made to cover specific areas, and if the room you put it in is bigger than the coverage area, you likely won’t get the best results. If the air purifier is designed to cover 500 square feet, which is typically the highest speed setting, then set it to 500 square feet or less. Otherwise, it won’t perform the way you want it to. For best results and livability, we suggest choosing an air purifier that can operate at twice the coverage area so you can keep your speeds at low/medium to minimize the fan noise.

Additionally, it’s important to make sure you check the warranty on the air purifier before you buy it. Mold can always come back, so you want to invest in a purifier that will last a long time or can be replaced if it doesn’t. We recommend running the air purifier 24/7 to keep your air fresh and free from mold.
