A water purification apparatus for purifying input water and dispensing a user selected quantity of purified water into a portable container in response to deposit of a predetermined amount of money. The apparatus comprises a first purified water path and a second purified water path. The first purified water path includes a reverse osmosis filter and a storage tank. The second purified water path includes an ultraviolet sterilizing unit connected between the tank and a dispensing unit with one or more dispensing valves. A recirculation water path periodically recirculates tank water through the ultraviolet sterilizing apparatus to improve and maintain the purity thereof. Another water recirculation path may be provided to recirculate concentrate from the reverse osmosis filter to a filter inlet line where it is mixed with input water.
