I ordered the size I needed and the 20x25 is a half in too small LxW. In order to get the exact size I need I have to special order then and it's 169. 00 for 6 of them.

I’m very happy to see all 3 filters now come in one box. The price increase was quite a shocker. Not sure if I will continue with on line purchase or buy local
