The 4" MERV 8 Furnace & AC Air Filter by Filters Fast® - 3-Pack is a set of MERV 8 filters that effectively reduces contaminants from your 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 8 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: These filters do not contain fiberglass.
