Description
The 4″ MERV 11 Furnace & AC Air Filter by Filters Fast® is a MERV 11 filter that effectively reduces pollen, dust, pet dander, mold spores, dust mites and other allergens from indoor air. Removing these airborne particles can help improve allergies and alleviate sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing. The Filters Fast® MERV 11 filter media is electrostatically charged and constructed with spun micro-fiber that also will not retain moisture, which can lead to microbial growth. Aside from the health benefits, these HVAC filters will also extend the life of your heating and cooling system by making it work more efficiently.
Note: This filter does not contain fiberglass.
