Description
This air filter is made to a 29-7/8 x 17-3/4 x 1″ nominal size for HVAC systems, air handlers, and return grilles that require an exact custom dimension rather than a standard retail size.
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.
This MERV 13 pleated filter is the highest-efficiency option we produce in the Exact Filters® custom-size line. It’s commonly chosen by allergy-sensitive households, buildings in wildfire-smoke regions, healthcare and education facilities, and anyone wanting the deepest particulate capture we offer.
Specifications
- Nominal size: 29-7/8 x 17-3/4 x 1″

The 29-7/8 x 17-3/4 x 1″ dimension is one of the many non-standard sizes we make on demand, serving both retrofit installations in older homes and light-commercial properties where the return housing dates to an older era of HVAC construction.
Features
- 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
