A filter arrangement includes a filter assembly, a filter housing, a seal member, and a moisture separator. The filter assembly has opposite first and second ends, a first axial length between the first and second ends, and a plurality of flutes. Each of the flutes has a first end portion adjacent to the filter assembly first end, and a second end portion adjacent to the filter assembly second end. Selected flutes are open at the first end portion and closed at the second end portion and other selected flutes are closed at the first end portion and open at the second end portion. The filter housing circumscribes the filter assembly. The seal member at least partially circumscribes the filter assembly. The seal member seals a joint between the filter assembly and the filter housing. The seal member also helps to secure the filter assembly within the filter housing. The moisture separator is positioned upstream of the filter assembly and collects moisture from an incoming air stream prior to entrance of the air stream into the filter assembly.
