A filter includes a pleated filter material with a plurality of pleats arranged circumferentially. The pleated filter material includes a top half and a bottom half. An end cap is coupled with an axial end of the pleated filter material bottom half, and at least a portion of the pleated filter material is tapered. With a smaller end cap, the filter has less area on which dust can accumulate.
