Description
Exact Filters® produces this 36-1/4 x 22-3/8 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 36-1/4 x 22-3/8 x 1″ slot the first time.
Even a quarter-inch of gap around a filter can allow a significant percentage of return air to bypass the media entirely, which is why the exact fit matters as much as the filter’s efficiency rating.
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.
