Description
Exact Filters® produces this 38-3/8 x 35-7/8 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 38-3/8 x 35-7/8 x 1″ slot the first time.
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.
At MERV 13, this filter removes a significantly larger share of fine particulate from your return air than standard mid-efficiency ratings — including smoke, bacteria-sized particles, and the fine dust that tends to resettle faster after cleaning. Because the media is denser, a properly sized HVAC system matters: check your blower’s static-pressure headroom before upgrading.

Common applications for a 38-3/8 x 35-7/8 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.
