Will an Air Purifier Remove Mold Spores?

One of the many common questions we see people asking about air purifiers is “Will an air purifier remove mold spores?” While this may seem like a simple question, there’s a little more nuance to it than you might expect. Let’s take a look at whether an air purifier can remove mold spores and what kind of air purifier you need for this purpose.


First, Let’s Answer the Question


The simple answer to this question is yes, an air purifier can filter mold spores out of the air. With that said, not all air purifiers are equipped to do this. To remove spores, an air purifier needs to have a HEPA filter, which is a type of filter used to remove solid particles from the air. On average, a mold spore is between 10 and 30 microns in diameter. A HEPA filter, meanwhile, must be able to remove particles as small as 0.3 microns at an efficiency of at least 99.97 percent. Because of this requirement, air purifiers with HEPA filters can actually remove mold spores quite easily.


Some air purifiers, however, aren’t equipped with filters meant to capture solid particles. Generally, these purifiers are specialized units meant to focus exclusively on gases or VOCs in the air. While most general-use air purifiers do have a HEPA filter, it’s important to keep in mind that not every air purifier on the market will have the ability to remove mold spores. Many air purifiers also combine HEPA filters with gas-focused filtration. These combination air purifiers can be very useful for dealing with mold, since they can help to remove airborne mold toxins as well as spores.


Will an Air Purifier Get Rid of Mold Growing in Your House?


Although an air purifier with a HEPA filter will remove mold spores, it won’t get rid of established mold already growing in your home. For that, you’ll need either thorough cleaning or professional mold remediation.
