ABSTRACT:
A filter apparatus has a rigid housing surrounding a piece of preferably self charging electrostatic filter material and having a preferably magnetic attachment device for mounting the filter apparatus directly in front of a grill at an end of a cold air return or supply of a forced air system, for a heating and/or air conditioning system. The filter and housing are generally sized so that the frame does not cover any of the openings on the grill over which it is designed to be placed. Decorative openwork is positioned in the front of the filter material to provide an aesthetically pleasing covering of what is considered less than attractive filter material.
