Product Information

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.

Delivered on time just what I ordered

I' 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.

I ordered these filters, and about 4 days later, they were on my doorstep! They fit well, they filter the air well, and are an excellent value for what you pay.

The filters are precisely sized, do an excellent filtering job and are long lasting. This is the second time I have ordered them from Filters Fast...

I received my 3-pack of filters and they were just what i needed for my system at an afordable price which is about 1/2 of what i would have paid at lowes (the only big box store that carries that size filter in my town).
