Description
Built to order in the precise 32-3/4 x 18-3/8 x 1″ dimension you need, this Exact Filters® air filter solves a problem standard catalogs can’t — a true custom fit for systems that don’t accept common filter sizes.
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.
