20x20x1 MERV 10 Pleated Air Filters
I am a Property Manager of several townhome communities and I love these filters. These are well made with a high MERV rating at the best possible price I could find anywhere in-store or online. I will only get my filters here and encourage all my tenants to shop here for their filters. Fast deliver, within a few days as well!

Good Experience
First time ordering and it came packaged well. Husband doesn’t believe in cheap filters so I ordered these. So far he likes the quality I guess in 3 months we will see how well they filter.
