Review on Enhanced FilterBuy 13X21 5X1 Pleated Furnace Filters by Joshua Albright

Wrong size. I ordered 13x21.5x1. The product had dimensions of 13x22x1 and therefore could not fit into the air intake without cutting it, which was not at all easy because of the wire. I should have just bought the brand I heard about because I've never had this problem. Aside from the size issue, it's made from cheaper materials than any other filter I've ever bought. I don't think it works as well as other brands. I leave it there waiting for the other to arrive, but it will be replaced as soon as possible.
