Description
This 36-1/2 x 27-1/2 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 36-1/2 x 27-1/2 x 1″ opening.
A custom-cut filter keeps every cubic foot of return air flowing through the media rather than around it, which is the foundation of any effective filtration setup.
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.
