Air purifiers mainly consist of high-voltage circuits, negative ion generators, ventilation fans, air filters, and other systems. During operation, the ventilation fan inside the machine circulates indoor air, and the polluted air is filtered through the air filter inside the machine to remove or adsorb various pollutants. In addition, a negative ion generator can ionize air, generate a large amount of negative ions, and send them out through a micro fan to form a negative ion flow, further cleaning and purifying the air.

Air purifiers play a crucial role in improving indoor air quality. Firstly, it can remove particulate matter such as dust and pollen from indoor air, reducing the risk of respiratory diseases. Secondly, air purifiers can remove microorganisms such as bacteria and viruses from indoor air, reduce the possibility of disease transmission, and provide a safe and healthy breathing environment for family members. In addition, air purifiers can also remove indoor odors such as smoke and pet odors, improve the indoor environment, and enhance living comfort.
