Abstract: A bacteria removing water generation device is provided. The device includes a hypochlorous acid containing water generating part generating water containing hypochlorous acid by electrolyzing tap water; a sterilizing metal ionic water generating part including electrodes, sterilizing metal ion being eluted from the electrodes into the tap water by electrolyzing tap water; a water discharge part discharging at least one of the water containing the hypochlorous acid and water containing the sterilizing metal ion; and a controller controlling operations of the hypochlorous acid containing water generating part and the sterilizing metal ionic water generating part. When a concentration of the hypochlorous acid in the water containing the hypochlorous acid is relatively low, a concentration of the sterilizing metal ion in the water containing the sterilizing metal ion is relatively high.
