Abstract: A device for cleaning air filters, either annular or rectangular in configuration, including a bottom plate member having a flat upper surface, an apertured vertical column connected to a high pressure air hose, and a top plate member, removable from the vertical column, having a flat bottom surface, where an annular filter is placed around the vertical column and top plate member is placed onto the vertical column, sealing the filter between the top plate member and the bottom plate member. Air is then forced into the vertical column, exiting through the apertures and through the filter itself, forcing any accumulated particles off the surface of the filter. Secondary air distributor apertures, connected to a secondary pressure hose fitting, are positioned on the upper surface of the bottom plate member for use with square or rectangular filters.
