PURPOSE:To make it possible to obtain tasteful and safe purified water for drinking or cooking, by setting the integrated amount of treating water up to the life based on the adsorbing limit of an adsorbent to 50-98% of the integrated filtering capacity of a porous hollow yarn membrane. CONSTITUTION:A water purifier is constituted by a means for putting a porous hollow yarn membrane and an adsorbent in one container or a means for connecting a container receiving the porous hollow yarn membrane and an adsorbent received container. In this case, it is necessary to set the integrated amount of treating water up to the life based on the adsorbing limit of the adsorbent to 50-98% of the integrated filtering capacity of the porous hollow yarn membrane. As the aforementioned adsorbent, activated carbon, silver deposited activated carbon or zeolite are used. As the porous hollow yarn membrane, one capable of inhibiting bacteria, fungi, algaes or iron colloid and filtering water under pressure obtained by a method other than this method such as water pressure at a tap water spigot or water surface head difference may be used.
