In a cartridge for removal of impurities from water, an elongated tube is charged, between water-permeable barriers, with ion exchange resin of a type capable of removal of bacteria from water. Outside one such barrier, an inlet cap is charged with water-soluble bactericide in a shelf-stable, water-activatable form. Preferably, the bactericide is sodium salt of dichloroisocyanuric acid, in granular form.
