Description
Exact Filters® produces this 34-1/2 x 36-1/8 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 34-1/2 x 36-1/8 x 1″ slot the first time.
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: 34-1/2 x 36-1/8 x 1″
- Actual dimensions: 34-1/2 x 36-1/8 x 3/4″

This 34-1/2 x 36-1/8 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
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
- Sold as a 12-pack so you have a full year of replacements on hand
- Orientation arrow printed on the frame to ensure correct airflow direction at install
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
