The air purifier mainly consists of a motor, a fan, an air filter, and other systems. Its working principle is that the motor and fan inside the machine circulate indoor air, and the polluted air passes through the air filter inside the machine to remove or adsorb pollutants, continuously ionize the air, produce a large number of negative ions, and be sent out by a micro fan to form a negative ion airflow, achieving the purpose of cleaning and purifying the air. With the improvement of people's living standards, there is a growing awareness of the importance of clean air for physical health. In order to improve the increasingly severe air environment, air purification products have become a popular product category in home appliance stores, among which air purifiers are favored by users as effective tools to improve indoor air environment.

A P+N dual core series MOS has also been launched for air purifiers to meet and respond to market development and changes.
