Description
Designed for homeowners and facilities managers dealing with an unusual 29-5/8 x 21-5/8 x 1″ filter housing, this Exact Filters® filter is produced on-demand to fit your opening precisely.
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.
