PURPOSE:To perform removal of dirt contained in hot water, stable sterilization of hot water and easy washing of a filter by providing both a filtration tank having a especial structure and the filter to a circulation path through which the hot water in a bathtub is sucked and redischarged into the bathtub. CONSTITUTION:Both a filtration tank 3 packed with natural stone 5 such as BAKUHANSEKI (medicinal stone contg. silicon dioxide or the like) and zeolite 4 including heavy metal to the inside thereof and a filter 6 provided with a filter medium, a refuse reservoir part, a water seal provided between both and a washing mechanism for performing discharge of the hot water in the refuse reservoir part to the inside thereof are provided to a circulation path 2 through which hot water in a bathtub 1 is sucked and redischarged into the bathtub 1. As a result, when the hot water flowing through the circulation path 2 is passed through the filter 5, hair or the like is removed by the filter medium. Furthermore when it is passed through the filtration tank 3, microorganisms propagating in hot water are brought into contact with the above-mentioned heavy metal and killed and thereby purified clean hot water is redischarged into the bathtub 1 and also cleaning and washing of this filter 6 can be performed while circulating hot water through this filter 6.
