PROBLEM TO BE SOLVED: To provide a filter having a temperature control function which can be used by switching a normal bath use and a water bath use with a simple input operation.SOLUTION: When a circulation pump 120 actuates, a circulation path of bathtub water is formed between a water inlet end 101 and a water outlet end 102 connected to a bathtub. A heat exchanger 150 is constituted so as to switch between execution and non-execution of heat exchange between a heat transfer medium from outside heat source equipment and bathtub water in the circulation path by control of a temperature adjustment valve 160. When a target temperature inputted in a remote control 500 is within a first temperature region, heat exchange in the heat exchanger 150 is executed when the bathtub water temperature is lower than the target temperature. On the other hand, when the target temperature is in a second temperature region, heat exchange in the heat exchanger 150 is executed when the bathtub water temperature is higher than the target temperature. The second temperature region is set to be lower than the first temperature region without having a temperature region overlapping with the first temperature region.SELECTED DRAWING: Figure 2 【課題】簡易な入力操作によって通常浴用途および水風呂用途を切換えて使用可能な温度調整機能を有するろ過機を提供する。【解決手段】循環ポンプ１２０が作動すると、浴槽と接続された入水端１０１および出水端１０２の間に、浴槽水の循環経路が形成される。熱交換器１５０は、温度調整弁１６０の制御によって、外部の熱源機器からの伝熱媒体と循環経路内の浴槽水との間での熱交換の実行または非実行を切換えるように構成される。リモコン５００に入力された目標温度が第１の温度領域内であるときには、浴槽水の温度が目標温度よりも低いときに熱交換器１５０での熱交換が実行される。一方で、目標温度が第２の温度領域内であるときには、浴槽水の温度が目標温度よりも高いときに熱交換器１５０での熱交換が実行される。第２の温度領域は、第１の温度領域と重複する温度領域を有することなく、第１の温度領域よりも低く設定される。【選択図】図２
