The FiltersFast FF4M11 3-Pack is a set of MERV 11 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 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.

Customer Reviews:
Delivered on time just what I ordered
Collected by Trustpilot.comI' ve been purchasing 4 inch filters for some time. Fast Filters is FAST at very low cost. Their ' packaging' for shipping leave a bit to be desired. Numerous times the filters arrived ' crushed' on one end or the other from shipping. To their credit, they have responded by replacing the damaged filters.
