Abstract: The disclosure describes a filter assembly comprising a housing having a liquid inlet and a liquid outlet and defining a liquid flow path between the inlet and the outlet; a generally cylindrical filter arrangement disposed within the housing in the liquid flow path and comprising a cylindrically shaped porous means for removing particulate contaminants from the liquid, a cylindrically shaped sorbent-containing means for removing chemical contaminants from the liquid, and a cylindrically shaped microporous means for removing microbiological contaminants from the liquid; and means for directing the liquid flow radially through the filter arrangement.
