Why You Need an Air Purifier for Mold
Mold spores are tiny (as small as 1–5 microns), airborne, and often undetectable until you’re sneezing or smelling must. That’s where air purifiers come in—especially AHAM-certified ones, which are independently tested and rated for cleaning power.
Here’s why AHAM-certified purifiers are your best bet:
-
✅ Tested for Clean Air Delivery Rate (CADR) in smoke, dust, and pollen
-
✅ Reliable measurements so you’re not guessing
-
✅ Filters that trap mold spores before they settle or spread
