Abstract: A media pack includes a filtration sheet and a support sheet that is made from a different material than the filtration sheet. The filtration sheet is coupled to the support sheet. The support sheet is corrugated such that, together, the filtration sheet and the support sheet form a plurality of channels. The channels are alternately sealed on opposing ends of the media pack. In one embodiment, the permeability of the support sheet is less than a permeability of the filtration sheet.
