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!

TLP/16x25x2 furnace filters

While I have not yet installed the newly received filters, I suspect they will work just fine. Construction seems nice and durable and I am sure they will perform satisfactorily at better price than what I was paying for the same sized filters from local retailers.
