The identification process can identify multiple objects without manual intervention. Moreover, it responds quickly and no mechanical malfunction will happen. Thus, the air purifier can operate under harsh environment and serve for a long time. In this manner, counterfeits can be effectively prevented and quality of products can be guaranteed.
