Description
Designed for homeowners and facilities managers dealing with an unusual 37-1/2 x 20-1/8 x 1″ filter housing, this Exact Filters® filter is produced on-demand to fit your opening precisely.
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.
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.
