Reusable modular multi-panel air filter

Abstract

An apparatus and methods are provided for a reusable multi-panel air filter to remove contaminants from air within interior building environments. The reusable multi-panel air filter comprises a multiplicity of reusable filter panels for filtering an airstream. A frame supports the filter panels within an HVAC system. The filter panels are angled with respect to one another to form adjacent V-configurations. Elongated openings in the frame allow the airstream to flow into the V-configurations and through the filter panels. Seats in top and bottom end plates of the frame maintain the V-configurations of the filter panels. The filter panels can be removed from the frame for servicing without removing the entire frame from the HVAC system. The filter panels can be cleaned by removing them from the multi-panel air filter, flushing contaminants from the filter panels, and allowing the filter panels to dry.
