Key points of air filter selection for automobile maintenance:
1. It is recommended to replace the air filter every 10,000km /6 months. The maintenance cycle of different models may vary slightly.
2. Before purchasing the goods, please be sure to check the information of the car type and the displacement of the car, so as to ensure the correct model of accessories.

3. During major maintenance, the air filter is usually replaced at the same time as the oil, filter and fuel filter (except the built-in fuel filter in the oil tank).
4. When using, the paper core air filter should be strictly prevented from getting wet by rain, because once the paper core absorbs a lot of water, it will greatly increase the inlet resistance and shorten the mission. In addition, the paper core air filter can not contact with oil and fire.
5. Air filter is our most commonly used automobile vulnerable product. If we use it for a long time, the filtration effect of air filter will decrease, and the suspended particles in the air cannot be effectively removed. Light people will accelerate the abrasion of cylinder, piston and piston ring, and seriously cause cylinder strain and shorten the service life of engine.
6. Filters filter dust and impurities in the air, oil and fuel. They are indispensable parts in the normal operation of a car. If the use of inferior air filters, air and fuel will not reach a certain degree of cleanliness mixed combustion, on the one hand may not be sufficient combustion, high oil consumption, high exhaust gas, heavy pollution; On the other hand, a large number of impurities enter the cylinder, causing serious damage to the engine over a long period of time.
