The emission of man-made pollutants from fixed and mobile pollution sources is one of the most important factors affecting air quality, including exhaust from vehicles, ships, aircraft, industrial production emissions, residents' living and heating, garbage incineration, etc. The development density of the city, topography and meteorology are also important factors affecting air quality.

[0003] 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 primary filter, medium filter, high efficiency filter and sub-high efficiency filter. Different models have different standards and performance.
