the only reason my rating isn't higher is that i didn't get the filter i ordered. it was the right size but not the correct merv rating. i said i would use the filter but just wanted you to know what happened. a refund for the price difference was promised. the filter fit fine. this is my first filter from your company and if it performs well it won't be the last.
I didn't see the "actual size" dimension before I bought 4 of these filters (a years supply). My filter section takes a full sized 20"x25"x4" filter, these are 5/8" small in the length and width directions an 3/8" shorter. While they do fit in the section they are very loose. While the filter quality appears good, I can't help but think there is air passing through my HVAC system around the filter in stead of through it.
