All is can tell you about the filter is it fit my a/c unit. I did not install it immediately. It was about a week. I think Iwould need to use it a month or so to determine how good it works. You have any questions.

This filter fits the area perfect easily installed and removed. I write installed date and change it every three months. Catches a lot of dust. House air feels cleaner.

I've been using FilterBuy for years and I order four sets annually. The price is reasonable and love the automatic ordering so my filters arrive just in time for the next change which I do every three months.

Not as snug as the OEM filter
on May 13, 2026
Posted by: Customer
This filter was about 1/4 inch shorter than the filter that came with the HVAC unit. I needed to pad the underside with strips of with cardboard, so that it would fit snugly up to the top of the slot, since air travels across the top.

I’m so happy I discovered Filterbuy. It is so convenient to have them come directly to your door when needed. It makes it easy to repair some on schedule. The filters are really nice quality.
