A filter includes a pleated filter element having longitudinally extending pleats and a wrap member wrapped around the filter element. The wrap member is joined to the peaks of the pleats and has openings for increasing the dirt capacity of the filter. The filter element may be a composite of a filter layer, upstream and downstream support and drainage layers, a cushioning layer between the upstream support and drainage layer and the filter layer, and polymeric beads on the downstream side of the downstream support and drainage layer. An extruded polymeric mesh may comprise one or both of the upstream and downstream support and drainage layers.
