Correct size

I like the Filter King filters very much . . . especially because they are the actual size indicated - example: a 11. 5 x 11. 5 x 1 filter is actually 11. 5 x 11. 5 x 1. This is important, because the A/C intakes is each bedroom are 11 9/16 x 11/9/16! Filter King is the only supplier that sell filters that are the right size for my A/C intakes!

Odd size filters in stock and ready to ship.

I have three different size filters in my home. Filter King had all three sizes in stock and the were shipped promptly and packaged extremely well to survive the shipping process. This is the easiest way to buy you filters for your home and very cost effective. B Marr
