FiltersFast 1" MERV 11 Air Filters - 6-Pack
FFM11 6pk



The FiltersFast FFM11 6-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 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.

- Part Number: FFM11
- Pack Size: 6 Filters

Collected by FiltersFast.comHave been using these filters for several years and am highly satisfied. Nice to have a 6 pack, so that I don' t have to reorder as often. They do a very good job at blocking small particles in the air.
Collected by FiltersFast.comFilters are as good or better quality as what I can get at Home Depot or Lowe' s, but at a fraction of the cost.

Collected by FiltersFast.comLove this site they always have the filters you need!
Collected by FiltersFast.comGood alternative to the expensive ones at the big box stores. Auto reorder means I never run out.
Collected by FiltersFast.comThese are awesome filters! I started using the Filters Fast MERV 11 filters 6 months ago and I just replaced the first one. I cannot believe how much this filter traps and how cost effective they are. I highly recommend these filters.
Collected by FiltersFast.comWoW!!!! I've lived in South Florida for over 30 years, I know A/C from the user perspective. These filters are really fantastic. Price is unavailable anywhere with this quality. Good job! Now how about those refrigerator water filters. Lets get them down in cost.
Collected by FiltersFast.comI picked this filter to replace the 3M Filtrete Red and Brown version. I am immediately impressed!! This brand is cheaper, and quite a bit more durable than 3M's version. Furthermore, it provides the same great protection of a 3M Filtrete at a fraction of the cost. I am sold and will continue to purchase this brand.
