PROBLEM TO BE SOLVED: To provide an air purification and greening device capable of facilitating drainage of irrigated water. SOLUTION: A planting section 40 in which soil S is filled and a plant P is planted, a housing 30 in which the planting section 40 is housed, and an outside of the housing 30 by sucking air inside the housing 30. A rear fan 50 that allows air to pass through the planting section 40, a pump 82 that irrigates the planting section 40, and a water tray 60 that drains the water irrigated to the planting section 40. The control unit 83 for controlling the operation of the rear fan 50 and the pump 82 is provided, and the control unit 83 is used for the first process of operating the rear fan 50 with the first suction amount and the operation of the pump 82. Correspondingly, a second process of controlling the rear fan 50 is performed so that the second suction amount is smaller than the first suction amount.
