The air purification equipment comprises two parts of air detection devicesand a purification main control device, wherein the air detection devices are respectively arranged at different indoor detection points. When the air purification device is initialized, the purification main control device can receive and analyze air quality information of different indoor detection points, which is sent by each air detection device. When the air quality of the at least one indoor detection point is not qualified, the purification main control device can sequentially perform air purification control on an area corresponding to each unqualified indoor detection point accordingto the air quality information of each unqualified indoor detection point.
