Air Purifier
Air purifier is mainly composed of motor, fan, air filter and other systems. Its working principle is: the motor and fan inside the machine make indoor air circulate and flow, polluted air will remove or adsorb pollutants after passing through the air filter inside the machine, ionize the air continuously and produce a large number of negative ions, which are sent out by the micro fan to form negative ion airflow to clean and purify the air. With the improvement of people's living standards, the more they realize the importance of clean air for their health. In order to improve the increasingly serious air environment, air purification products have become a popular product category in the home appliance stores, of which air purifiers as an effective tool to improve the indoor air environment and favored by users.
