ABSTRACT:
An air cleaner incorporating a plurality of filtration techniques within a rigid, gasketed frame designed to fit in conventional filter tracks. A perimeter gasket attached to the frame leaving air side provides a positive seal thereby preventing air from bypassing the frame. The frame houses, in series from the entering air side, a replaceable dry-type media filter coated on its leaving air side with a viscous substance, and a synthetic weave having a charge separation producing local electrostatic effects. The replaceable media effectively comprises two stages of filtration; dry-type media filtration, and viscous impingement filtration. Air passing through the instant filtration configuration is efficiently cleaned with little resistance.
