20" x 25" x 1" Polyester Throw Away Replacement Filter

It's getting harder to find decent quality air filters in the lower MERV range. I have HEPA filters throughout the house so wanted low impact filters for my older HVAC. I tried the Rheem brand from the local hardware but those were so flimsy and ill fitting I was literally afraid they would get bent and sucked into the ductwork. Saw a recommendation for this brand and decided to give it a try. Much sturdier construction and perfect fit. I also had occasion (resulting from my own confusion) to reach out to SupplyHouse support. All I can say is WOW; stellar support. This was my first purchase from the company and I will check them now each time I need home hardware. Very pleased all around.
