Description
Exact Filters® produces this 38-3/8 x 30-3/4 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 38-3/8 x 30-3/4 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 is the top efficiency offered in the Exact Filters® line. It captures the broadest range of airborne particles we make, including fine dust, smoke particles, and the submicron fraction that carries many allergens and bioaerosols. Buildings dealing with wildfire smoke, indoor air-quality concerns, or sensitive occupants commonly step up to this rating.

Customers typically order a 38-3/8 x 30-3/4 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
- Suitable for forced-air furnaces, central AC, heat pumps, and packaged HVAC systems
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
