　　Introduce the common types of air purifiers from a functional point of view

　　1. Basic purification type-the main functions include the filtration of airborne particles, the removal of odors, and the treatment of decoration pollution. The main principle is to adopt multiple filters, including larger particles, fine particles (including PM2.5 or even smaller) filters, activated carbon filters, etc., characterized by mature technology, strong practicability, and low maintenance costs.

　　2. Decoration pollution control type-the basic technical principle is still the use of filters, but it is more excellent in pollution control. In addition to activated carbon technology, some more professional adsorbents will be used. These products not only have a basic air filtration function, but also have a more professional function of removing harmful substances. Due to the replacement of special adsorbents, the maintenance and use costs of such products are relatively high.

　　3. Disinfection and sterilization type-in addition to the basic filter, some technologies such as ozone inactivation, electrostatic inactivation, ultraviolet light, and negative ion adsorption will be used to kill bacteria and viruses in the air. The product cost and price are relatively high, and maintenance The cost will not increase too much.

　　4. Fresh air ventilation type-such as fresh air fans, are essential in central air conditioning systems and office ventilation systems, and can also be seen in some high-end residences. We can also regard this type of product as a more professional air purifier.

　　This type of equipment generally requires professional installation and has a large air exchange rate. The main function is air filtration and purification, and it has no effect in the treatment of harmful substances and disinfection. In the past two years, some small household products have also appeared, which may be more abundant in terms of functions. The characteristics of this type of product are stronger and more professional.
