In order to solve the above-described problems and achieve the object, the air purifier of the present disclosure includes a housing, an air blowing unit, an air cleaning function unit, a CO 2 detection unit, a contamination level detection unit, and a control unit. and a signal transmitter . The housing has an inlet and an outlet. The air blowing unit is arranged inside the housing, sucks indoor air from the suction port of the housing, and blows the air into the room from the blowing port. The air cleaning function unit cleans the air sucked from the suction port by the air blowing unit. The CO 2 detector detects the indoor CO 2 concentration. The pollution level detection unit detects the pollution level of indoor air. The control unit uses the CO 2 concentration detected by the CO 2 detection unit to determine whether or not there is a person in the room, and based on the CO 2 concentration and the contamination level detected by the contamination level detection unit, the air blower unit to control the air volume of the The signal transmission unit transmits a signal to a ventilation device provided in the room. The control unit transmits from the signal transmission unit an operation signal for controlling the air volume of the ventilation device based on the CO 2 concentration detected by the CO 2 detection unit, and the CO 2 concentration in the room is lower than a predetermined third reference value . is large, the operation signal to increase the air volume of the ventilation device is sent from the signal transmission unit, and after transmitting the operation signal to increase the air volume of the ventilation device, if the degree of contamination rises, the air volume of the blower unit is maintained, the exhaust of the ventilator is suppressed, and an operation signal is transmitted through the signal transmission unit to increase the supply of air.
