Abstract: A water faucet for the supply of germ-free water for human consumption comprises a faucet housing which is spatially separated from a water pipe that is arranged within the faucet housing. A contact protector with overflow openings is provided on a water outlet end of the faucet housing. The overflow openings prevent contaminated water from entering into the faucet, even if the water outlet of the faucet were to be blocked. An aerator is fastened on a discharge end of the water pipe inside the faucet housing. An air-gap is provided between the aerator and the water outlet opening of the contact protector. Internal surfaces of the faucet housing and of the contact protector are coated with a photocatalytic material such as titanium dioxide and are exposed to UV-A light from an ultraviolet light source while and after water is flowing through the water pipe.
