This 38-3/8 x 26-3/8 x 1 Exact Filters air filter is manufactured to your exact dimensions, eliminating the guesswork of matching an off-the-shelf filter to a non-standard 38-3/8 x 26-3/8 x 1 opening.
A properly fitting filter seals against the housing, so all return air is forced through the media instead of leaking around the frame.
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.

Common applications for a 38-3/8 x 26-3/8 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

- Cardboard frame with reinforced media for structural stability during handling and installation
- Pleated construction (or fiberglass, depending on MERV tier) designed for balanced capture and airflow
- Sold as a 12-pack so you have a full year of replacements on hand
