Description
Exact Filters® produces this 30-1/8 x 12-3/8 x 1″ filter to your measurements, so instead of trimming, taping, or forcing a “close enough” size into place, you drop in a filter that fits your 30-1/8 x 12-3/8 x 1″ slot the first time.
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: 30-1/8 x 12-3/8 x 1″
- Actual dimensions: 30-1/8 x 12-3/8 x 3/4″
- Efficiency rating: MERV 13

This 30-1/8 x 12-3/8 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
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Orientation arrow printed on the frame to ensure correct airflow direction at install
- Sold as a 12-pack so you have a full year of replacements on hand
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
