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!

Haven’t had them long enough to give a review. Also there isn’t a notation on them regarding how long they last, is it 3 months?

I recently purchased 3 different sizes of filters. Two fit perfectly one was not the size it said it was it was 3/4 inch shorter than it said it was therefore I could not use it. I will have to reach out again to see if the problem can be easily & quickly resolved. I will try during regular business hours.

It is easy to find the sizes or size you need. You might order a few more extra to go with here like I did. I have to tell you great quality filters, great buy, and ships to your house! What a fabulous concept!
