Description
When your HVAC system calls for a 29-3/4 x 25-7/8 x 1″ filter and the standard aisle doesn’t carry it, this Exact Filters® unit is cut to your exact 29-3/4 x 25-7/8 x 1″ spec — no shims, no gaps, no bypass air.
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.

Customers typically order a 29-3/4 x 25-7/8 x 1″ custom filter because their system is older, was built by a regional manufacturer, was retrofitted, or was framed on-site by an installer who didn’t conform to a standard filter dimension. If that describes your situation, you’re in the right place.
