[0002] Air filter refers to air filtering device, which is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery and communication equipment. There are five types of filters: primary filter, medium filter, high-middle filter, sub-high efficiency filter and high efficiency filter. Commonly used air filters include housing, filter, air inlet and outlet, etc. The air entering the housing is filtered through the filter, thereby reducing the dust content of the air entering the workshop. With the continuous development of industrial technology, in order to provide a better workshop production environment, the structure and function of air filters are also being gradually improved.
