Description
This air filter is made to a 29-5/8 x 28 x 1″ nominal size for HVAC systems, air handlers, and return grilles that require an exact custom dimension rather than a standard retail size.
Filter bypass — air slipping past a loose frame instead of through the pleats — is one of the most common reasons a filter underperforms its MERV rating in the real world. A precise fit closes that gap.
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: 29-5/8 x 28 x 1″
- Actual dimensions: 29-5/8 x 28 x 3/4″

- Quantity: 12 filters per carton
Customers typically order a 29-5/8 x 28 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
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
- Made to your exact 29-5/8 x 28 x 1″ specification — no trimming or taping required at installation
- Cardboard frame with reinforced media for structural stability during handling and installation
- Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
