How often do you change the air filter?

The oil filter should be replaced every 5000 km or half a year, and the air filter should be replaced every 15000 km or every 1 year. Mechanical filter is a kind of oil filter, also known as oil grid, which is divided into full-flow type and split-flow type. Used to remove impurities such as dust, metal particles, carbon deposit and soot particles in engine oil and protect the engine. Air filtration refers to a device for removing particulate impurities in the air. Air filtration consists of filter element and shell, and there are three ways: inertia, filtration and oil bath. Its key requirements are high filtration efficiency, low flow resistance and long-term continuous use without maintenance. What is the purpose of air filtration? The primary function of air filtration is to purify the gas into the car, but the ultimate destination of this environment is the car engine. If the air filtration is intimate, the gas entering the automobile engine will be cleaner and the motor will play a better role. At the same time, it will also reduce the generation of carbon deposits, so air filtration should be updated immediately. The automobile engine must be changed on time during the oil change, but between oil changes. General vehicles need to be lubricated every 5000 kilometers. If the automobile engine grease is removed and replaced for a long time, not only will the grease be moldy due to excessive residue, but also the mechanical equipment will be damaged more, and it may also cause internal damage to the automobile engine. It is also not allowed to increase the replacement cycle time of grease, and the damage to the automobile engine is not trivial. In the next maintenance, we should bear in mind that car maintenance involves not only the removal and replacement of grease, but also other parts that are very easily damaged. Like a grease filter.
