Abstract
Abstract A housing having a water pump mounted therein so as to receive water from a reservoir by gravity flow and supply water to a first container partially filled with activated carbon. A blend of water flowing directly from the first container and water flowing from the first container through a second container filled with ion exchanger material is introduced into a third container having an ultraviolet radiating lamp mounted therein to eliminate bacteria and virus from the water. Water from the third container is heated or cooled as desired and is then ready for consumption. The various containers and the reservoir are formed of a low-density plastic.
