Description
Built to order in the precise 28 x 34 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.
Specifications
- Nominal size: 28 x 34 x 1″
- Actual dimensions: 27-3/4 x 33-3/4 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
Customers typically order a 28 x 34 x 1″ custom filter because their system is older, was built by a regional manufacturer, was retrofitted, or was framed on-site by an installer who didn’t conform to a standard filter dimension. If that describes your situation, you’re in the right place.
Features
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Orientation arrow printed on the frame to ensure correct airflow direction at install
- Sold as a 12-pack so you have a full year of replacements on hand
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
