A filter media for use in a filter employed to separate water and particulate material from a liquid to be purified, such as a hydrocarbon fuel. The filter media includes a porous material such as glass fiber having a density sufficient to provide the desired mechanical filtration and which carries a water insoluble, water-absorbing material as, for example, a starch-polyacrylonitrile graft copolymer. Also disclosed is a filter employing the media and a method of making the media.
