A filter of a water purifying apparatus main body which is housed in a sink is made as a positive electrode, and a DC voltage is applied, by a dry battery cell, between the filter and a negative electrode in a purified water passage. Thus, microbes are prevented from proliferating in tap water which remains in the water purifying apparatus main body. A discharge pipe of the water faucet used exclusively for purified water is made as a negative electrode, and a DC voltage is applied, by the dry battery cell, between the positive electrode in the outlet of a cartridge and the discharge pipe. Thus, microbes are prevented from proliferating in tap water which remains in the water faucet used exclusively for purified water.
