Abstract
A filter element includes a center tube and a blank of a filter media. The center tube has a first end and a second end. The blank is folded into a plurality of triangles. Each triangle is disposed adjacent to another of the plurality of triangles to form a series of triangular pleats to form a pleated filter media. The pleated filter media is disposed about the center tube. A cross sectional area of the pleated filter media proximal to each of the first end and the second end is greater than a cross sectional area of the pleated filter media at a point between the first end and the second end.
