Abstract: A water-purifier device, comprises a housing to be mounted vertically, a water inlet, a water outlet, and two tubes extending generally horizontally of the housing when the housing is mounted vertically. The first tube defines a first water flow passageway including a filter for removing solid particles and a quantity of activated carbon for removing undesirable odors and tastes from the water flowing through the first flow passageway. The second tube defines a second water flow passageway connected between the first tube and the housing outlet, and including an ultraviolet lamp subjecting the water flowing therethrough to ultraviolet radiation.
