Reusable multi-pocket air filter

Abstract

An apparatus and methods are provided for a reusable multi-pocket air filter to remove contaminants from air within interior building environments. The reusable multi-pocket air filter comprises a multiplicity of reusable filter bags for filtering an airstream. A frame supports the filter bags within an HVAC system. The filter bags are arranged parallel to one another and extend downstream of the frame when the airstream flows into the filter bags. Elongated openings in the frame allow the airstream to flow through the frame into the filter bags. The elongated openings include filter bag retainers for individually coupling the filter bags with the frame. The filter bags can be removed from the frame for servicing without removing the frame from the HVAC system. The filter bags can be cleaned by removing them from the multi-pocket air filter, flushing contaminants from the filter bags, and allowing the filter bags to dry.
