Automobile air filter element is mainly responsible for the removal of particulate impurities in the air device. When piston type machinery works, if dust and other impurities are contained in the inhaled air, it will aggravate the wear of the parts, so it must be equipped with air filters. The air cleaner is composed of a filter core and a shell. The main requirements of air filter are high filtration efficiency, low flow resistance, can be used for a long time without maintenance.

A car engine is a very delicate piece of machinery, and even the smallest impurity can damage it. Therefore, before the air enters the cylinder, it must be filtered by the car air filter element before it enters the cylinder. The automobile air filter element is the patron saint of the engine. The state of the automobile air filter element is related to the service life of the engine. If the car runs using dirty car air filter, it will make the engine intake insufficient, the fuel combustion is not complete, resulting in the engine work is not stable, power decline, increase in fuel consumption phenomenon. Therefore, the car must keep the air filter element clean.
