Because the air purification module 20 can generate a certain amount of ozone during the operation of purifying air, the ozone concentration detection module 30 is disposed at the air outlet of the air purification module 20 and between the air purification module 20 and the ozone reduction module 40. After the air purification module 20 discharges the purified air from the air outlet, the ozone concentration detection module 30 located at the air outlet of the air purification module 20 detects the ozone concentration of the purified air discharged from the air purification module 20. The ozone concentration detection module 30 sends the detected ozone concentration to the control module 10 connected thereto. The control module 10 compares the ozone concentration sent by the ozone concentration detection module 30 with a preset ozone concentration threshold. When the control module 10 determines that the concentration of ozone sent by the ozone concentration detection module 30 is greater than or equal to the threshold value of the concentration of ozone by comparison, the control module 10 determines that the ozone reduction of the ozone generated by the air purification module 20 is currently required. Control module 10 generates a start command and sends the start command to ozone reduction module 40 located after air purification module 20 and ozone concentration detection module 30, and ozone concentration generated by air purification module 20 is reduced by ozone reduction module 40.
