A filter cartridge is described for use in a system to remove impurities from the air. The cartridge has a filter section which may provide tortuous air flow channels between an inlet and an outlet of the filter section. The filter section may be formed from a pair of adjoined sheets with at least one of the sheets having an internally directed raised pattern thereon. This raised pattern spaces the adjoined sheets. The adjoined sheets may be rolled-up into a spiral shape and are positioned in the cartridge with said sheets paralleling an air flow direction through said filter section. It is also contemplated that the raised pattern of the adjoined sheets provide linear air flow channels but ones which are less than three millimeters in height. Alternatively, the filter section may comprise an open pore sponge or foam. The cartridge may be provided with an inlet closure plate having openings therein so as to impart turbulence to incoming air.
