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.

Quality and convenient four-pack
Size: 12x24x1
Exactly what I needed and love the idea that it comes in a four pack which makes it much more convenient when it's time to change my filters. They are quality made at a decent price. Will purchase again when needed!
