Description
Exact Filters® produces this 29-5/8 x 20-7/8 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 29-5/8 x 20-7/8 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 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.

Common applications for a 29-5/8 x 20-7/8 x 1″ custom filter include retrofit installations, legacy HVAC systems installed before standard sizes were codified, built-in return grilles that were framed to non-standard dimensions, and commercial unit housings that don’t match any current off-the-shelf size.
Features
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Cardboard frame with reinforced media for structural stability during handling and installation
- Replace approximately every 90 days in standard installations; shorter intervals in high-dust, smoky, or heavy-use environments
- Orientation arrow printed on the frame to ensure correct airflow direction at install
