PURPOSE: To supply clean air and oxygen by stopping supply of oxygen or opening a second solenoid valve to supply clean air when the concentration of indoor oxygen is not less than reference value. CONSTITUTION: In a system for supplying clean air and oxygen by an air cleaner purifying contaminated indoor air and an oxygen generator inhaling outdoor air and discharging pure oxygen, the system comprises a control means (A) installed to buildings of the air cleaner and the oxygen generator and supplying clean air and oxygen to each households. The control means comprises a gas holder (5) controlling amount of the oxygen and the clean air supplied to each household through an oxygen supply line and a clean air supply line, an oxygen measurement sensor (2) measuring the amount of oxygen of each household with opening the gas holder, a control part (6) stopping the supply of the oxygen when the amount of oxygen measured by the oxygen measurement sensor exceeds over reference value and supplying the clean air, a first solenoid valve (1) controlling the supply amount of the oxygen supplied through the oxygen supply line according to the control of the control part and a second solenoid valve (4) controlling the supply amount of the clean air supplied through the clean air supply line according to the control of the control part.
