PROBLEM TO BE SOLVED: To enable filling water in a device through the use of a self-supply pump not by means of a manual work by executing a water filling operation through the use of a non-self-supply pump in the case of a normal operation and the self-supply pump in the case of filling water and executing control to change-over into the operation of the non-self-supply pump after a water filling state is recognized. SOLUTION: When a user indicates a water filling command or an operation start command with an operating device 6, a controller 5 drives the self-supply pump P2, permits it to fill water, stops the pump P2 after the end of water filling, changes-over the driving of the non-self-supply pump P1 and executes the normal operation in configuration. A configuration where a water existence sensor is arranged in the duct or the filter tank T of the device or the like as a means for detecting the end of water filling and the water filling end is detected by a detecting signal from the sensor is adapted. By the bath water purifying device with the configuration, water filling is executed by the pump P2 and the burden of the user is relieved.
