If you use these filters they will fall out of the filter housing in the HVAC unit as they are too small. Other products (3M) fit perfectly. Their product description says 19-3/4" square. But the actual dimensions are 19-1/2" square. I had to add 1/4" foam tape on all edges to hold the filter in place. Also, due to the loose seal, unfiltered air will bypass the filter. Won't buy it again as it's too expensive.
