用が比較的高くつくという問題をもつ。As a conventional water purifier, there is known one having a filter having an adsorbent such as activated carbon. In that type of water purifier, the filter is usually replaceable because the function of removing impurities by the filter, that is, the water purification function is difficult to reproduce. When the water purifying function of the filter deteriorates or is expected to deteriorate due to the use of the water purifier with time, the desired water purifying function is obtained by replacing the filter. This type of water purifier has a problem that the maintenance cost is relatively high because the filter needs to be replaced.
