Description
This 29-3/4 x 23-1/4 x 1″ Exact Filters® air filter is manufactured to your exact dimensions, eliminating the guesswork of matching an off-the-shelf filter to a non-standard 29-3/4 x 23-1/4 x 1″ opening.
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 targets the fine particulate fraction that lower MERV ratings allow through — including smoke, bacteria-carrying dust, and combustion byproducts. Airflow resistance is higher than MERV 8 or 11, so systems with borderline static pressure should be evaluated before switching up.
Specifications
- Nominal size: 29-3/4 x 23-1/4 x 1″
- Actual dimensions: 29-3/4 x 23-1/4 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
Customers typically order a 29-3/4 x 23-1/4 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
- Cardboard frame with reinforced media for structural stability during handling and installation
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
- Orientation arrow printed on the frame to ensure correct airflow direction at install
