How to judge the quality of an air purifier from a professional point of view?

　　To judge the professionalism of an air purifier, you only need to look at the purification efficiency, performance characteristics, filter material, and secondary pollution of the air purifier.

　　1. Purification efficiency: under the same time, what is the efficiency of its purification of air. The higher the purification efficiency, the better.

　　2. Performance characteristics: see what advantages this product has. If it has negative ion function, it is a priority.

　　3. Filter material: The filter element is a consumable and has a service life. According to different materials, different environmental pollution levels in the area of use, and different lifespans, the general use time is 6 months. The general filters are HEPA mesh and activated carbon mesh. Both are given priority.

　　4. Whether there is secondary pollution: secondary pollution is mainly caused by the release of ozone. A small amount of ozone can achieve the effect of sterilization and disinfection, but once the ozone reaches the standard, it will cause secondary pollution. Therefore, when purchasing a product with ozone function, it is necessary to strictly control the amount of ozone released.

　　It is not practical to judge an air purifier. What can the air purifier do? What kind of air purifier do I need? How big is the applicable area of the air purifier.
