Great product, I have been using the merv 11 (21x22x1 a/c filter for several years now and they work great. However my last ship came and I noticed that the measurements on the box label 21x22x1 were not the same as on the filters. The measurements on the filters are 20 3/4 x 21 3/4 x 1. These filters are a 1/4 smaller than what I was getting before. I still have not used one due to the fact that I still have two of the old ones so I hope that these new ones fit my a/c. I am sure that a 1/4 in will not affect the quality of the product, but I am concerned as to why the different measurements. Other wise I will recement this product and company to ours.
