We were getting the Furnace filters from a local home improvement place. The filters we received are a much better quality not as flimsy.

When I received them everything was fine. They seem to be of quality. My last air conditioner was ruined by the air filter being too small and the filter housing was installed incorrectly. Thats why I wanted a good quality air filter. So thank you very much its just what I was looking for.

Ordered 20x25x4 for aprilair system and the size of filter is off by 2inches. It would be better if filter buy has a exact measurements
