    Abstract: A fluid filter cartridge which includes a dual stage filtration media, the first stage of which is a precleaner of depth medium composed of a foamlike material for removing contamination of a first predetermined fineness and a second stage surface medium which may be composed of a pleated paper or felt-type media which removes contaminations passed by the first stage filter. The cartridge is further characterized by the foamlike medium having convolute structural configuration on one surface thereof which causes the material of the foamlike medium to bear evenly on the pleated paper filter media.
