Description
Exact Filters® produces this 36-1/2 x 30-7/8 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 36-1/2 x 30-7/8 x 1″ slot the first time.
Even a quarter-inch of gap around a filter can allow a significant percentage of return air to bypass the media entirely, which is why the exact fit matters as much as the filter’s efficiency rating.
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: 36-1/2 x 30-7/8 x 1″

Customers typically order a 36-1/2 x 30-7/8 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
- Orientation arrow printed on the frame to ensure correct airflow direction at install
- Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
- Made to your exact 36-1/2 x 30-7/8 x 1″ specification — no trimming or taping required at installation
- Sold as a 12-pack so you have a full year of replacements on hand
