Description
Designed for homeowners and facilities managers dealing with an unusual 39-1/4 x 30 x 1″ filter housing, this Exact Filters® filter is produced on-demand to fit your opening precisely.
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: 39-1/4 x 30 x 1″
- Actual dimensions: 39-1/4 x 30 x 3/4″
- Efficiency rating: MERV 13
- Quantity: 12 filters per carton
This 39-1/4 x 30 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
- Sold as a 12-pack so you have a full year of replacements on hand
- 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
