Abstract
Abstract A removable debris filter for an air conditioning condensing unit. The filter preferably comprises a quantity of fiberglass screen material having a drawstring seam attached onto opposite ends thereof. The screen material is wrapped around all four vertical sides of the air conditioning condensing unit and is held in place thereon by pulling each drawstring tight and tying a knot. The fineness of the screen mesh is adequate to prevent most airborne debris from entering the condensing unit, and the drawstrings allow the filter to be easily removed from the condensing unit for cleaning.
