MERV RATING: 7 - FPR "Filter Performance Rating": 5 - Specifically Designed to Filter Larger Airborne Particles. 28 times more effective than fiberglass filters and will last up to 3 months. Pleated filter material significantly increases the surface area on which airborne particles can be trapped (as compared to Fiberglass Filters). The additional surface area extends the filter life to 3 months. Pleated filter material will also achieve higher MERV ratings than fiberglass filters because it is made to trap much smaller particles. The Pleated Filter Media filters airborne allergens like dust, dirt, and pollen. 100% Synthetic filter media will not support the growth of Bacteria, Mold, or Fungi in normal use.

Rated 4.3 out of 5 by 9 reviewers.
Rated 4.0 out of 5.0 by I have a odd size and it is hard to find a good air filter. Have not used these very long but I think they will do the job I think they are a good filter for the money. Now I know where I can find them. Will be ordering more from Home Depot. I have good luck ordering things on line and delivered to the store. February 17, 2015
Rated 5.0 out of 5.0 by Great product, great shipping I ordered online because this is an odd size and no longer available in store. However, I was able to sip to the store for free and go pick it up just a few days later. Perfect! And the filters are exactly what our HVAC service recommends for good air flow to prevent the AC freezing up during the summer. May 27, 2014
Rated 4.0 out of 5.0 by Excellent quality for price. Within a week of replacing a fiberglass filter with this one, we noticed we had less stuffiness when we awoke in the morning. Our air quaility has significantly improved. Also, there seemed to be no reduction in air flow or cooling efficiency. The only reason why I gave it 4 stars instead of 5 is because a few of the filters are a little deformed on the edges--making them a little difficult to insert. On the other hand, I'm satisfied enough that I'm on the third pack. I would definitely recommend this product. September 27, 2011

Rated 5.0 out of 5.0 by The best price I found this deal with Home Depot and actually was the best deal for air filter and was delivered for free. Thanks Home Depot! August 21, 2013
Rated 5.0 out of 5.0 by This filter made a difference in the quality of air we were breathing. we stopped sneezing and felt better. This product has been very effective in cleaning up the air in my new home. May 7, 2013
Rated 3.0 out of 5.0 by Good for air quality, but restricts airflow The company that serviced my AC actually recommends a spun fiberglass filter - even though you would have to replact it every month. They noted that while these trap a lot more allergens, they tend to restrict air flow and cause your system to work that much harder. July 31, 2012
