Decided to filter the cold air returns rather that using a large filter in the air handler. These fit the returns in the bedrooms perfectly. The qulity is excellent. Our goal was to eliminate as much dust as possible. So far, so good.

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.
