PROBLEM TO BE SOLVED: To provide an air purification device having a stable volatilization amount of hypochlorous acid. SOLUTION: Water is supplied from a water supply unit 17 into a first water storage compartment 24, and water is stored in a water storage container 16 inside the second water storage compartment 25 and around the second water storage compartment 25. It has the 1st detection part 40 which detects the maximum amount of water, and the 2nd detection part 41 which detects the required minimum amount of water stored in the water storage container 16. The control unit 4 for controlling the water supply unit 17 is provided by the detection signals from the first detection unit 40 and the second detection unit 41. When the control unit 4 detects the detection signal from the first detection unit 40, the water supply unit 17 is detected. When the water supply from the second detection unit 41 is stopped and the detection signal from the second detection unit 41 is detected, the water supply from the water supply unit 17 is started, and the communication hole 27 is located below the water surface where the second detection unit 41 detects the required minimum amount of water. It is characterized by being arranged.
