Medium Filter
A box-type medium filter that catches what the pre-filter misses and stretches the life of the HEPA behind it. Its wide media area holds a lot of dust before pressure drop climbs. Three grades — 65, 85 and 95% by ASHRAE 52.1 colorimetric — with header and bag types in the same family.

The suffix (-95/-85/-65) is the ASHRAE 52.1 dust-spot efficiency grade. Pressure loss is constant within a grade; flow and weight vary by size. Custom sizes available.
