Car negative ions serve to sterilize and purify the air. The in-car purifier equipped with a negative ion function can absorb harmful substances in the air, sterilize and purify the air inside the vehicle, ensuring the health of the occupants. The car purifier, also known as a car negative ion purifier, consists of a circuit negative ion generator, a micro fan, an air filter, and other systems. The working principle of the car purifier is that the micro fan inside the machine circulates the air in the car, the PM2.5 filter in the car filters various pollutants, and finally, the negative ion generator continuously ionizes the air to produce a large number of negative ions. After being sent out by the micro fan, it forms a negative ion airflow, which can clean and purify the air.
