Air filter is one of the three major filters. Compared with mechanical filter and oil filter, the impurities of oil and fuel can be slightly controlled, but air impurities can only be filtered by air filter, so it is particularly important to maintain air filter.
Generally, it is often heard from the shops and service stations in 4S that the air filter is changed once every 5,000 kilometers for cars and once every 0/0000 kilometers for big cars. Are the words of service providers with relevant interests reliable? If the air condition of the car we drive is good, don't we need to change the air filter?
If the air filter is not dirty or broken, there is no need to replace it. And if the air filter is not particularly dirty, you can blow it slightly with compressed gas.
It is not only the working condition but also the material that affects the service life of air filter. Take the cart as an example, the air filter with particularly good quality can be used for a long distance, and the materials used are also better. Such as nano-materials, such as some patented materials. At present, the best nano-materials can use 60,000 to 65,438+10,000 kilometers, and other processes can use more than100,000 to150,000 kilometers compared with black technology. Represented by Procter & Gamble's 10F9, there are few recycled products on the market. Some nano-filters can refer to the imported brand Donaldson and the domestic Procter & Gamble. Well-made nano-air filters can run over 60,000.
