I really love getting my filters

The convenience of getting my filters by subscription is great! I never have check the size and then remember to get them at the store then get them home without crushing them in the car. I was buying them several at a time but that took up a lot of space. I am very happy with the price, quality and convenience.

These are tough!

I wanted to see if I could remove the filter material and mesh from a used merv 8 filter, to use the paperboard frame for another purpose. No way; it was like trying to disassemble a unibody car! No wonder these filters hold their shape so well. They're built like tanks
