すように細菌数を制御するには限界がある。However, according to the conventional water purification filter using activated carbon, active chlorine contained in the chlorine-containing water passing through the filter is inactivated, so that the sterilizing power of the active chlorine is lost. It is not possible to supply chlorine-containing water having sterilizing power to the downstream side of the filter medium. In addition, when activated chlorine is inactivated, there is a problem that the filter medium is contaminated by the propagation of bacteria adsorbed thereon, thereby increasing the water flow resistance and causing the propagated bacteria to flow downstream of the filter medium to cause bacterial contamination of the filtered water. .
When the filter medium becomes a hotbed of bacteria, there is a limit in controlling the number of bacteria so as to satisfy safe water quality standards, even if bacteria are removed using active chlorine downstream of the filter media.
