Overview

Our Polly Series 21x21x1 high efficiency filters are available in five different filtering efficiencies - MERV 6, 8, 11, 13 and 13 Minipleat, plus a MERV 8 OdorBan option. They're constructed of 100% synthetic fibers that are electrostatically charged to capture dust particles as small as a microscopic 0.3 microns, sending cleaner air through your system and home.

We can even include a length of foam gasketing with your order. Once inserted around the perimeter of the filter housing, it will help eliminate any air by-pass around the sides of the filter frame. You can order the Gasket set below.
