A channel filter is provided by corrugated fluted flow channels folded back and forth transversely to the pleats. Fluid moves along an axial flow direction from upstream to downstream in a housing. Initially, a sheet of filter media is corrugated in a serpentine sinusoidal pattern along a set of pleat bend lines. The bend lines extend axially to form axially extending fluted flow channels. The sheet then ha a plurality of creases or folds formed laterally across the pleat bend lines, and the sheet is then folded back and forth upon itself along plurality of runs.
