Abstract: Filtration media, media packs, and filtration elements are described, including fluted filtration media having offset flutes arranged to intermittently contact flutes on adjacent media, including angled and curved flutes. Pleated filtration media with alternating sealed pleat edges are also disclosed, including fluted media with alternating sealed flutes. A media pack can have a first sheet of media and a second sheet of media. The first sheet of media can have a first plurality flutes defining first flute valleys extending between a first face and a second face of the media pack. The second sheet of media can have a second plurality of flutes defining second flute peaks extending between the first face and the second face of the media pack. The first plurality of flutes can be non-parallel to the second plurality of flutes, and each first flute valley contacts one second flute peak at a discrete contact point.

Abstract: A filter element has a sheet of filter media having a first elongate edge and a second elongate edge. The sheet of filter media defines a plurality of pleats, a first set of pleat folds and a second set of pleat folds, where each of the plurality of pleats extend between the first set of pleat folds and the second set of pleat folds. The first set of pleat folds each extend from the first elongate edge to the second elongate edge, and the second set of pleat folds each extend from the first elongate edge to the second elongate edge. Each of the plurality of pleats defines a repeating wave pattern of flute peaks and flute valleys alternating from the first set of pleat folds to the second set of pleat folds. Each of the flute peaks and flute valleys extend from the first elongate edge to the second elongate edge.
