Exact Filters produces this 38-5/8 x 12-1/2 x 1 filter to your measurements, so instead of trimming, taping, or forcing a “close enough” size into place, you drop in a filter that fits your 38-5/8 x 12-1/2 x 1 slot the first time.
A properly fitting filter seals against the housing, so all return air is forced through the media instead of leaking around the frame.
This MERV 13 pleated filter is the highest-efficiency option we produce in the Exact Filters custom-size line. It’s commonly chosen by allergy-sensitive households, buildings in wildfire-smoke regions, healthcare and education facilities, and anyone wanting the deepest particulate capture we offer.
