Abstract
A room air filter apparatus includes a multi-sided housing having longitudinally spaced first and second ends, a plurality of sides between the first and second ends, and a plenum inside the housing. Each of the sides has an empty space frame by outer edges of the housing side. A fan is mounted to the housing and is operably disposed, preferably, within the plenum to draw air from the plenum and to exhaust the air outside of the housing. Filter panels are removably attached to the outer surfaces of the edges and filter material is mounted in the panels to cover the empty spaces. Magnets mounted on edges of the panels may be used as attachment devices as well as other devices for clipping the panels onto the outer surfaces of the edges of the housing. The filter material is preferably a self-charging electrostatic washable material.
