Description
When your HVAC system calls for a 38-1/4 x 29-3/4 x 1″ filter and the standard aisle doesn’t carry it, this Exact Filters® unit is cut to your exact 38-1/4 x 29-3/4 x 1″ spec — no shims, no gaps, no bypass air.
A properly fitting filter seals against the housing, so all return air is forced through the media instead of leaking around the frame.
MERV 13 is the top efficiency offered in the Exact Filters® line. It captures the broadest range of airborne particles we make, including fine dust, smoke particles, and the submicron fraction that carries many allergens and bioaerosols. Buildings dealing with wildfire smoke, indoor air-quality concerns, or sensitive occupants commonly step up to this rating.
