The car purifier is also called a car purifier or a car Air Purifier, which usually consists of a high-voltage generating circuit negative ion generator, a micro fan, an air filter and other systems. Its working principle is as follows: the micro-fan (also known as ventilator) in the machine circulates the air in the car, and the polluted air passes through the PM2.5 filter and activated carbon filter in the machine to filter or adsorb various pollutants, and then After the negative ion generator installed at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), the air is continuously ionized to generate a large number of negative ions, which are sent out by the micro fan to form an air flow of negative ions to achieve the purpose of cleaning and purifying the air.
