Abstract: A portable water purifying device is disclosed which includes a main housing provided with a main inner chamber to receive a purified water receptacle. An electric circuit provides a main "on-off" switch to provide a flow of water in its "on" position, from a suitable pressurized source through a purifying capsule into a suitable container such as a jug. When the container is full a limit switch shuts off the water flow and a signal light is illuminated. The container is removed and replaced with another empty container. In preferred form of the invention, a refill switch is provided to deenergize the signal light and to initiate another water purifying and container filling cycle.
