Quality is phenomenal. Fit is always perfect though I just ordered replacements because I accidentally ordered 10x10x1 when I should have ordered 10x10x4 . That sucks when you buy Merv 13; however my mistake so when the correct size comes in I will be utmost satisfied. Now what to do with the wrong sizes? 2 plus years this is my filter go to warehouse
This is my second order. The filters are top quality and out perform others I have had. I have Asthma and allergies and these filters make my existence sooo much better.
