　　How to choose an air purifier

　　1. The choice of function

　　If it is mainly used for the purification of indoor air inhalable particulate matter, a filter-type air purifier with HEPA technology can be used. HEPA high-density filter material is currently one of the most advanced air filter materials in the field of indoor air purification. It can filter and adsorb pollutants above 0.3 microns, and has a strong purification ability for smoke, inhalable particles, bacteria and viruses; At the same time, catalytic activated carbon has a better purification effect on harmful gases such as peculiar smell, and has the ability to kill bacteria. Now most types of equipment adopt these two technologies.

　　If you also consider the function of anti-virus and sterilization while filtering the air, you can consider purifiers with technologies such as negative ions, high-voltage static electricity (very safe), ozone, and ultraviolet rays. In addition to the basic air filtration function, these products also have a certain killing effect on bacteria and viruses in the air.

　　2. Noise and applicable area

　　Since air purifiers have exhaust, ventilation and filtering functions, noise is inevitable during operation. Generally speaking, products with a large ventilation volume and applicable area produce more noise, and pure filter products produce relatively large noise. There are many products that are very effective in air purification, but fish and bear's paws cannot have both, and they may not be satisfactory in terms of noise control. In terms of noise and applicable area, shopping malls, hospitals, offices and other places have more requirements for applicable area and less requirements for noise. For home users, it may be the opposite. You should consider it when buying.
