Exact Filters 39-3/8″ x 32-3/4″ x 1″ Pleated MERV 13 Premium HVAC Replacement Filter (12-Pack)

Description

When your HVAC system calls for a 39-3/8 x 32-3/4 x 1″ filter and the standard aisle doesn’t carry it, this Exact Filters® unit is cut to your exact 39-3/8 x 32-3/4 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.

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.
