Since the raw water does not pass through the water purifier cartridge 20 while the raw water is directly guided to the shower head 3, neither of the primary filter 24 and the secondary filter 25 needs to exert the raw water purification function. The life of the filters 24, 25 is not shortened at all.

On the contrary, while keeping the faucet 2 held as described above, the flow path is switched so that the intake port 13 and the raw water supply port 15 communicate with each other and the purified water intake port 16 and the water supply port 14 communicate with each other. When the valve 12 is operated, raw water is once guided to the water purifier cartridge 20 and then to the shower head 3 (see FIG. 2). Therefore, the primary filter 24 removes chlorine and organic substances, and the secondary filter 25 removes fine impurities such as bacteria, iron rust, mold, and turbidity to become purified water, and this purified water is used as the shower head 3 Is discharged like a shower. As a result, the shower can be used in a state where the skin is not affected by residual chlorine, various bacteria and the like.

Therefore, when taking a shower, it is possible to prevent adverse effects on the skin by discharging purified water from the shower head 3, and when cleaning the bathtub, the raw water is discharged from the shower head 3. By doing so, the inconvenience of shortening the life of both filters 24, 25 can be prevented in advance.
