Air purifiers used in cars are ineffective.

Car air purifier:

Also called car air purifier and car air purifier, it refers to a car air purifier specially designed to purify PM2.5 and toxic and harmful gases ( Air purification equipment for in-car pollution such as formaldehyde, benzene series, TVOC, etc.), odor, bacteria and viruses. 2016 Zhongguancun Online Technology Product of the Year Award Selection Golden Raspberry Award: Won the 2016 Golden Raspberry Marketing Award.

Working principle:

Car purifiers are also called car purifiers or car air purifiers. They are usually composed of high-voltage generating circuit negative ion generators, micro fans, air filters and other systems. . Its working principle is as follows: the micro fan (also called a ventilator) in the machine circulates the air in the car, and the polluted air filters or adsorbs various pollutants after passing through the PM2.5 filter and activated carbon filter in the machine, 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 produce a large number of negative ions, which are sent out by the micro fan to form a negative ion airflow to achieve the purpose of cleaning and purifying the air.

Types (four types):

Filter type vehicle air purifier; electrostatic dust collection type vehicle air purifier; ozone vehicle air purifier; plasma cluster vehicle air purifier .
