A self supported cylindrical corrugated filter. The corrugations of the filter define a first and second end. Two arcuate side walls join the first and second end. The filter has a substantially planar front surface and a substantially planar rear surface. The front and rear surfaces extend the length of the filter. The arcuate side walls have a plurality of overlapping folded flaps. Each one of the plurality of flaps is joined to at least one adjacent flap from the plurality of flaps to form the self supported filter.
