Perfect fit, great price

Had a hard time finding the right size filter for my air return at a decent price. FilterBuy had what I needed at great price and now it’s set up on auto order so I don’t even have to think about it. Great service, great product, better price.

I have been purchasing these filters for several years. The cost is reasonable and I cannot always find this size in the stores. When I do, they are very expensive for one. They work very well in our furnace.

The correct 3M replacement for my Rudd AC unit is 19"7/8 x 19"7/8 X 4" 9/16 which 3M labels as 20" x 20" x 4" This is my perfect exact fit.
