Patent ID: 8888885

Claim:
A pleated filter media extending in an axial direction, a transverse direction that is perpendicular to the axial direction, and a lateral direction that is perpendicular to the axial direction and perpendicular to the transverse direction, the pleated filter media comprising: a plurality of pleats comprised of pleat segments extending in the axial direction between first and second axial ends and extending in the transverse direction between first and second sets of pleat tips which are at least partially defined by first and second sets of bend lines; wherein axial flow channels are defined between the pleat segments in the lateral direction; wherein the plurality of pleats has a width in the transverse direction that varies along the axial direction at least along a portion of the plurality of pleats; and wherein the portion of the plurality of pleats comprises at least a first linear portion extending at a first angle to the axial direction and a second linear portion extending at a second angle to the axial direction, wherein the first angle and the second angle are different.
