EXAMPLE A resin (sterilization medium) mixed with silver ions was prepared, a bacteria elimination medium was mixed into a bath water sample the next morning, and the number of bacteria was examined. Disinfection medium 2% of "Bactequila" (manufactured by Sinanen Co., Ltd.) in which 2.2% of silver ions are supported on zeolite is kneaded with a polystyrene resin, and extruded to form pellets of about 2 mm. And 2% was added to the bath water, and the mixture was stirred. After 1 hour of live bacteria per 1 cc of bath water 1.6 × 10 ⁶ After 6 hours 0

As is clear from the above results, according to the sanitizing water purifier of the present invention, silver ions of 0.6 ppb or less are eluted in water, which contributes to the sanitizing action. This amount of silver ions is harmless to the human body, but since silver ions are also removed by the filter in the filtration space, the silver ions are made harmless to a lower concentration and can be used as drinking water.
