[WapCar] Car air purifier refers to the air purification equipment that is dedicated to the purification of PM2.5, toxic and harmful gas (formaldehyde, benzene series, TVOC, etc.), peculiar smell, bacterial virus and other pollution in the car. It is usually integrated in the air conditioning system or in the central armrest box.
Working Principle
The car purifier is usually composed of the high-voltage generating circuit negative ion generator, micro fan, air filter and other systems. It works as follows: the micro fan (also called ventilator) in the machine makes the air in the car circulate flow, the polluted air passes through the PM2.5 filter and activated carbon filter to filter or absorb various pollutants, then pass through the negative ion generator installed in the air outlet (the high voltage in the negative ion generator generates direct current negative high voltage when working), the air is continuously ionized to generate a large amount of negative ions, which are sent out by the micro fan to form a negative ion airflow, reaching the purpose of cleaning and purifying the air.
