What are the functions of a car air filter? 

Air filters can make the interior of your car cleaner. The air filter is a car product and consists of a filter element and body. Its main requirements are high efficiency of filtering, low flow resistance and prolonged continuous use without maintenance.

When the engine works, it consumes a lot of air. If the air does not filter, suspended impurities from the air will enter the cylinder, affecting friction between the piston and the cylinder, and in severe cases the cylinder may stretch. Air filter is a device that is primarily responsible for removing solid particles from the air.

The air filter is equivalent to protect the engine, cleaning and filtering particles of sand and dust in the air to prevent the effect on the engine of external pollution and affect its normal operation. Good service and long service life of your engine are largely due to the protective effect of the filter.
