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, as a device that can effectively improve indoor air quality, are gradually being favored by people. This article will provide you with a detailed introduction to the working principle, classification, selection points, and important role of air purifiers in improving indoor air quality.

Air purifiers mainly use various technical means such as physical filtration, electrostatic dust removal, chemical adsorption, negative ions, etc. to remove pollutants such as particles, bacteria, viruses, and harmful gases from indoor air, thereby improving indoor air quality. Its working principle can be summarized as inhaling indoor air, undergoing multi-layer filtration and purification treatment, and then releasing fresh and clean air back into the room.

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.

Air filters use specific filtering materials to intercept and adsorb harmful substances such as particles, bacteria, viruses, pollen, dust mites, etc. in the air, thereby achieving the goal of purifying the air. Common filtering materials include fiber filter materials, activated carbon, high-efficiency filter paper, etc. They can capture particles of different sizes and effectively improve indoor air quality.
