Filters are a little bit too small causing some whistling in the frames that hold them.

Florida living brings lots of sand into my house. My filterbuy filters catch the sand and save my air conditioner.

Merv 11 pleated Air Filter

I bought these to replace my Merv 8 filters, and find them to be much better. They also seem to last at least 3 months. Shipment was very prompt.
