　　Working Principle:

　　The air purifier is mainly composed of a motor, a fan, an air filter and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove various pollutants. Or adsorption, some models of air purifiers will also install a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), which continuously ionizes the air to generate a large number of negative ions, which are sent out by the micro fan. The formation of negative ion airflow achieves the purpose of cleaning and purifying the air.

　　Now, We have a thorough understanding about the air purifier. In the severe environment of the epidemic--COVID-19, it is indeed very practical.
