Description of the Related Art Conventionally, removal of turbidity, odor and harmful substances contained in tap water has been conventionally performed by a combination of activated carbon and a porous hollow fiber membrane. In recent years, a water purifier that removes metal ions such as lead and aluminum using an ion exchange resin has been provided. However, while foreign matter (turbidity, odor, and harmful substances) can be removed from tap water, there has been a problem that bacteria grow in the water purification section (activated carbon, ion exchange resin, porous hollow fiber membrane). As an antibacterial means of activated carbon, an effect is obtained by impregnating activated carbon with silver or a silver compound. Ion exchange resins have technical problems, and at present, antibacterial measures have not been applied.
