With the increasingly serious environmental pollution in the country, the content of inhalable suspended particles in the air is becoming higher and higher. If these suspended particles enter the cylinder of a car engine, a large amount of colloidal substances and small wearable particles will affect the combustion charge of the car engine, and enter the cylinder and piston of the engine, causing wear of piston related components, resulting in a decrease in engine performance. The function of a car air filter is to form a filtering barrier between the air entering the cylinder, completely blocking the suspended particles outside the cylinder, and ensuring sufficient air intake, which can ensure that the power of the car engine is not lost.
However, many private car owners do not pay enough attention to the maintenance of air filters, and inevitably encounter some misunderstandings when using car air filters. Below, I will explain the misunderstandings of using car air filters for everyone.

Mistake 1: Not paying attention to quality when purchasing air filters
Although many car owners nowadays choose 4S stores when replacing their air filters, with a deeper understanding of car construction, it is also very easy to replace the car filters themselves. However, whether replacing them at 4S stores or on their own, it will involve the issue of purchasing a new air filter. However, many car owners do not have a very correct understanding of the role of air filters, and often choose cheap and poor quality air filters. These poor quality air filters have average air filtration ability, especially for small suspended particles, and have poor physical stability performance. Long term use will inevitably lead to a decline in car engine performance and a significant increase in fuel consumption.

Mistake 2: Frequently removing car air filters when using them
Some private car owners believe that the car air filter does not play a significant role. After a new car has been in use for a period of time, the air filter has completely blocked, so they simply remove the air filter and do not replace it. The result of doing so may not affect the performance of car engines in the short term, but in the long run, the wear and tear of car engines is very serious. Data shows that without automobile air filter, the wear rate of automobile engine cylinder will exceed eight times, the wear rate of piston will exceed three times, and the wear rate of piston ring will exceed nine times.

Mistake 3: The maintenance of car air filters is not flexible enough
Most private car owners also know the importance of replacing car air filters, but when replacing car air filters, they are limited by the car maintenance operation manual and follow the mileage provided in the guide before replacing the car filter. However, with the varying levels of urban pollution nowadays, the corresponding amount of suspended particles varies. If it is in heavily polluted northern cities, the replacement and maintenance of car air filters cannot be simply carried out according to the instructions. At this time, the condition of the car is often abnormal, so it is necessary to shorten the maintenance cycle and improve the quality of the car filter. This is the correct way to maintain.
