Abstract
A shower head for purifying water includes a filter cartridge positioned within in a holding part, a purified water flow path passing through a purification material and a raw water flow path not passing through the purification material. A flow path switching valve switching between the purified and raw water flow paths is incorporated in a head part. A delivery flow switching valve positioned downstream of the flow path switching valve switches between a straight delivery port and a shower delivery port. The valves are controlled independently of each other. A germicidal ceramic and/or sintered magnetic body is installed in the flow path between the valves.
