Indoor air pollution detecting and purifying prevention method

An indoor air pollution detecting and purifying prevention method, for locating air pollution in an indoor space and implementing detection, filtration and purification, comprising:

• providing a plurality of gas detection devices, disposed in the indoor space for detecting the air pollution, wherein the plurality of gas detection devices detect and output air pollution data, wherein no more than 13 of the gas detection devices are installed per 10 ping of the indoor space, and a ratio of the maximum number of the gas detection devices to the area of the indoor space is ranged from 1.3 to 13;
• providing a connection device, wherein the connection device receives and compares the air pollution data detected by the gas detection devices for computing and determining the location of the air pollution in the indoor space and issuing a controlling instruction;
• and
• providing a plurality of filtration devices disposed in the indoor space, each of the plurality of filtration devices comprising a gas detection device disposed therein and a driver for receiving air pollution data detected by the gas detection device;
• determining whether the air pollution data exceeding a safety detection value or not by the driver, wherein when the air pollution data exceeds the safety detection value, or the driver receives the controlling instruction, the driver controls the corresponding filtration device to be enabled,
• wherein the connection device issues the controlling instruction to enable the filtration device closest to the location of the air pollution, and then issues the controlling instruction to further enable the rest of the filtration devices to generate a directional airflow convection, so that a flow of the air pollution is accelerated by the directional airflow convection to move toward the filtration device closest to the location of the air pollution for being filtered and cleaned.
