臭等が発生するという問題がある。In such a water purifier in which activated carbon and a hollow fiber membrane filter are combined, particularly tap water purifier, residual chlorine in the tap water causes bacteria contained in the tap water to be in an inactive state, resulting in an activated carbon layer. After the residual chlorine has been removed,
Bacteria are captured by the hollow fiber membrane filter, but since there is no residual chlorine in the filtered water that reaches the hollow fiber membrane filter, the bacteria captured by the hollow fiber membrane filter are activated for a long period of time, There is a problem that an odor of hydrogen sulfide is generated by anaerobic bacteria.
