These preassembled box filters are a huge improvement over the accordion filter I had to load in the support frame, what a pain.

Can't give a review. Just received them and have not used them yet. I'm using the old ones that I still have. Maybe when I get to the Filter Buy ones I will be able to send in a review. But thanks for the fast service.

20x20x5 Filter

I went on line and ordered 2 filters. I had a 20x20x5 filter in the furnace and came right out. The 2 new filters are too big and do not fit.
