MERV RATING: 11 - FPR "Filter Performance Rating": 6 - Specifically designed for families with allergies and pets. 53 times more effective than fiberglass filters and will last up to 4 months. During the manufacturing process, we charge the filter media with an electric current. This process allows the filter to attract very small particles much the same way magnets attract metal. The end result is a far more effective filter. The Electrostatically Charged filter media filters sub-micron airborne allergens like dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke and smog. 100% Synthetic filter media will not support the growth of Bacteria, Mold, or Fungi in normal use.

Rated 3.7 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by Great Product I have used nothing other than these filters for approx. ten years. They have always lasted beyond the three month service life. My Heat Pump tells me when to replace the filter if air flow becomes restricted. I replace the filters after the three months have expired. When routine service is performed the technicians have always told me that the filters are doing a very good job. October 15, 2014
Rated 4.0 out of 5.0 by Great filter for a low price I love these filters. This is the second time I've ordered them from and I remain pleased with them. They do a great deal of taking particulate matter out of my househould air. When it's time to change them, I notice the house getting a bit dustier. I've recently (last 6mo) had some home renovation going on, so there's plenty of dust floating around, and I remain impressed that they take such a large chunk of it out of the air. I've even set up a reminder to reorder these before I run out (again!). January 22, 2011
Rated 5.0 out of 5.0 by Perfect for our needs This filter works great! Forced air ventilation + Dog = Lots of Dust. Am continuously amazed at how much this filter traps and holds so it won't keep circulating through the house. Very pleased with these filters and will continue to purchase. December 27, 2011
Rated 5.0 out of 5.0 by These are great filters. These filters are great if you have allergies and/or pets. December 17, 2013
Rated 2.0 out of 5.0 by Good product ruined by shoddy packaging! Whomever packed the box ruined one filter completely by shoving it in and crushing it. Was NOT shipping damage, somebody just didn't care about quality. September 26, 2012
Rated 1.0 out of 5.0 by Horrible shipping Product is what I ordered, but the box it came in was banged up badly. 4 filters in the box, 2 of the 4 (one on each outside), were badly damaged. I considered going to the store to complain, but figured I would get nowhere since I ordered on line. Liked the price, but disappointed in how it was shipped. October 4, 2011
