On the other hand, the predetermined area of the first cover 230 is preferably made of glass to easily check the internal conditions of the second body portion 210 with the naked eye. Of course, when the entirety of the second body 210 is made of a transparent glass material, it is easier to check the internal conditions during the filtration process or the backwashing process.

The third member 300 is located above the second member 100, and is mainly filled with raw water to be purified, but may be filled with an activated carbon filter medium layer (AC) in some areas.
