The 1" MERV 11 Furnace & AC Air Filter by Filters Fast® - 6-Pack is a set of MERV 11 AC and Furnace Air filters that effectively reduce 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 MERV 11 filter media is 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: These filters do not contain fiberglass.
