PURPOSE:To filter warm water to clearness immediately after natural stone is washed. CONSTITUTION:Washing water or warm water is caused to flow in a tank filter 4 to wash natural stone in the tank filter 4 in a state of immersion in water. The contaminated washing water after washing is discharged from a washing water discharge valve 11 to remove the foreign matter stuck and deposited on the natural stone with bacteria living in the natural stone. Therefore the foreign matter stuck on the natural stone is selectively removed from the bacteria living in the natural stone, allowing the warm water to be effectively kept clear even immediately after the natural stone is washed.
