METHOD FOR PREVENTING AND HANDLING IN-CAR AIR POLLUTION

A method for preventing and handling in-car air pollution includes providing an out-car gas detector to detect a polluted gas outside a car and transmit an out-car gas detection data; providing an in-car gas detector to detect a polluted gas in an interior space of the car and transmit an in-car gas detection data; providing an in-car gas exchange system for controlling and determining whether to introduce a gas outside the car into the interior space, where the in-car gas exchange system includes a cleaning unit for filtering and purifying the polluted gas in the interior space and a control driving unit for receiving and comparing the out-car gas detection data with the in-car gas detection data; and filtering and exchanging the polluted gas in the interior space after the control driving unit compares the out-car gas detection data with the in-car gas detection data.
