Description
Built to order in the precise 36-1/4 x 35-1/4 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.

Common applications for a 36-1/4 x 35-1/4 x 1″ custom filter include retrofit installations, legacy HVAC systems installed before standard sizes were codified, built-in return grilles that were framed to non-standard dimensions, and commercial unit housings that don’t match any current off-the-shelf size.
Features
- Cardboard frame with reinforced media for structural stability during handling and installation
- Made to your exact 36-1/4 x 35-1/4 x 1″ specification — no trimming or taping required at installation
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
