Exact Filters 38.25 x 32.875 x 1 Inch Pleated Air Filter, MERV 13 Efficiency, Pack of 12

Description

This 38-1/4 x 32-7/8 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 38-1/4 x 32-7/8 x 1″ opening.

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.

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 38-1/4 x 32-7/8 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.
