I appreciate the the help

After first ordering the wrong size, I called to return them. I was prepared for an additional charge for the return and a higher price for the corrected size. Instead I was told to just donate the incorrect size and a new 6-pack of the corrected size sent immediately and received in 2 days! This was a perfect fit! Now I just have to change the filter in the A/C every other month and I'm set for the year! Thanks bunches!

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
