The size selection and filter rating provided everything I needed, and the shipment was very fast. I'm good for awhile, thank you.

You barely took an allowance from the width and length in turn I had to cut it down to fit into the receptacle. Will not be reordering

We were getting the Furnace filters from a local home improvement place. The filters we received are a much better quality not as flimsy.

It looks like better quality than the rest!

When I received them everything was fine. They seem to be of quality. My last air conditioner was ruined by the air filter being too small and the filter housing was installed incorrectly. Thats why I wanted a good quality air filter. So thank you very much its just what I was looking for.

Ordered 20x25x4 for aprilair system and the size of filter is off by 2inches. It would be better if filter buy has a exact measurements
