Excellent filters that do a great job. After educating myself on furnace filters I was surprised to learn that higher MERV numbers can put a strain on your air conditioning system and furnace. These are much more affordable and are very effective at filtering the air. I’m allergic to everything and these work just fine.

Well Made and Fits Good

Size: 16x25x1

This filter seems to be the best made one that I've bought that I consider to be a good value, and I've bought many brands -- with the board frame beig the primary reason, but filter media is just as good and probably better too.
