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 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.

knvmay Monday, July 23, 2018

Decent filters for reasonable price. Ship fast but last filters I received the corners got mashed in during shipping. I flattened them back out the best I could. Seem to be okay, just have to watch they don&#039 t get sucked into the vent.
I&#039 ve ordered filters several times before and this is the first time I&#039 ve had any issue.
Good price on my filters

bill620 Thursday, July 19, 2018

Have been using these filters for several years and am highly satisfied. Nice to have a 6 pack, so that I don&#039 t have to reorder as often. They do a very good job at blocking small particles in the air.
Filters are good

Filters are good. Didn&#039 t arrive as quickly as I thought.
Great Value!
bob_stantley Thursday, July 19, 2018

Filters are as good or better quality as what I can get at Home Depot or Lowe&#039 s, but at a fraction of the cost.

Molly - Baltimore

These 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.

LARRY - MACK

WoW!!!! 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.
Great Deal
Eric B - Texas

I 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.
