How often should the air filter in a sedan be replaced?

According to the car's maintenance manual, it should be replaced every 10,000 to 20,000 kilometers or once a year. It is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The location of the car's air filter element varies depending on the intake form and the engine's structure. It is generally located in the air filter on the engine's intake pipe. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. The function of the air filter: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder and preventing floating dust from being sucked into the engine, which could accelerate the wear of the piston group and cylinder. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. The engine sucks in a large amount of air during operation. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. A dirty air filter: Using a dirty air filter while driving can cause insufficient engine intake, incomplete fuel combustion, leading to unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car's air filter must be kept clean. The car's air filter is a device that removes particulate impurities from the air, consisting of one or more clean air filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinder to reduce early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, air must pass through the air filter's fine filtration before entering the cylinder. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if it is found to have little dust and minor blockage, it can be cleaned with high-pressure air from the inside out and continue to be used. Excessively dirty air filters should be replaced promptly.
