Description
Built to order in the precise 38-1/4 x 33-3/4 x 1″ dimension you need, this Exact Filters® air filter solves a problem standard catalogs can’t — a true custom fit for systems that don’t accept common filter sizes.
Even a quarter-inch of gap around a filter can allow a significant percentage of return air to bypass the media entirely, which is why the exact fit matters as much as the filter’s efficiency rating.
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.

The 38-1/4 x 33-3/4 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.
