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.
This MERV 11 pleated filter is engineered for buildings where filtration matters — allergy-prone households, sites with pets, properties near construction or agriculture, light-commercial spaces with elevated particulate loads — but where the HVAC system wasn’t originally specified for the higher static pressure of a MERV 13.
Specifications
- Nominal size: 28 x 34 x 1″
- Actual dimensions: 27-3/4 x 33-3/4 x 3/4″
- Efficiency rating: MERV 11
- 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
- Cardboard frame with reinforced media for structural stability during handling and installation
- Sold as a 12-pack so you have a full year of replacements on hand
- Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
