A water purifier includes an outer housing, an inner housing disposed in the outer housing, and a filter element disposed in the inner housing. The outer and inner housings have top openings, respectively, each closed by a lid. The inner housing and filter element can be removed as a unit from the outer housing when the lid of the outer housing is removed. The outer and inner housings include interconnected water inlets for admitting unfiltered water, interconnected filtered-water outlets for discharging filtered water, and interconnected unfiltered-water outlets for discharging unfiltered water when the filter element is to be replaced. The filtered-water outlets and unfiltered-water outlets are disposed adjacent the bottom of said outer housing. Valves can be provided in the water inlets, the filtered-water outlets and the unfiltered-water outlets, which valves are biased closed when the inner housing is removed from the outer housing, and which are opened in response to the inner housing being installed in the outer housing.
