Description
This air filter is made to a 29-7/8 x 7-3/8 x 1″ nominal size for HVAC systems, air handlers, and return grilles that require an exact custom dimension rather than a standard retail size.
A properly fitting filter seals against the housing, so all return air is forced through the media instead of leaking around the frame.
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: 29-7/8 x 7-3/8 x 1″
- Actual dimensions: 29-7/8 x 7-3/8 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
This 29-7/8 x 7-3/8 x 1″ filter size is frequently ordered by homeowners with older systems, property managers handling mixed-vintage HVAC equipment, and facilities maintenance teams servicing buildings where no two return grilles seem to measure the same.
Features
- Made to your exact 29-7/8 x 7-3/8 x 1″ specification — no trimming or taping required at installation
- Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
- Orientation arrow printed on the frame to ensure correct airflow direction at install
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
