Abstract

See full text

Pleated filtration media, media packs, filter elements, and methods for filtering fluid are provided which contain three dimensional tapered flutes in the media surface, the flutes configured to improve filter performance. In certain embodiments the flutes have defined peaks that reduce masking between adjacent pleats, the flutes have ridges along their length to modify flute cross sectional geometry, and/or the flutes provide for volume asymmetry across the media.
