Review on 🌀 Nordic Pure 20x25x4 Pleated Furnace Filter by Adam Madden

Fits and works well; much better than the OE that came with the system. Don't believe all the bad reviews (Filters usually get a lot of bad reviews because people order by nominal size. 2x4 isn't really 2"x4" ;-) .). BEFORE ORDER; Take a few minutes and write down the actual size of your old filter (should be printed on the page and all vary by manufacturer), then measure your system's filter opening (e.g. my system may use a slightly larger filter) . than what was included). LAST: Read the description on Revain for actual size, check, order and enjoy clean air!
