Description
When your HVAC system calls for a 38-3/8 x 36-1/4 x 1″ filter and the standard aisle doesn’t carry it, this Exact Filters® unit is cut to your exact 38-3/8 x 36-1/4 x 1″ spec — no shims, no gaps, no bypass air.
Filter bypass — air slipping past a loose frame instead of through the pleats — is one of the most common reasons a filter underperforms its MERV rating in the real world. A precise fit closes that gap.
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.
