[0002] Automobile air filter is an automobile product, which consists of two parts: filter element and shell. Automobile air filter is mainly responsible for removing particulate impurities in the air. When piston machinery (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of parts, so air filter must be installed. The main requirements of air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. After the air filter has been used for a period of time, the air filter element in the filter needs to be removed for cleaning or replacement, and then the new air filter element or the cleaned air filter element is installed in the air filter to ensure the use effect of the air filter element.
