Description
This 38-3/8 x 35-1/2 x 1″ Exact Filters® air filter is manufactured to your exact dimensions, eliminating the guesswork of matching an off-the-shelf filter to a non-standard 38-3/8 x 35-1/2 x 1″ opening.
A properly fitting filter seals against the housing, so all return air is forced through the media instead of leaking around the frame.
MERV 13 is the top efficiency offered in the Exact Filters® line. It captures the broadest range of airborne particles we make, including fine dust, smoke particles, and the submicron fraction that carries many allergens and bioaerosols. Buildings dealing with wildfire smoke, indoor air-quality concerns, or sensitive occupants commonly step up to this rating.
