I owe part of my 3 star rating to not reading the filter specs closely enough to determine the "actual size" is 11 3/4 inches. My recirculation grates are recommended at 12" x 12", but are actually 11 1/2" x 11 1/2" or 1/2" smaller than advertised. It is in order. I wrongly assumed they would meet this normal reduced standard. They are actually too big for my 12" x 12" return air grilles. I'm keeping them as it's my fault for not reading the full specs. High quality filters, just make sure you take a quick measurement before purchasing. .
