The specific replacement cycle depends on the purpose of the vehicle and the vehicle environment. If the car often runs in dusty or foggy conditions, the replacement cycle should be shortened and replaced every 10000 km. At ordinary times, we should form the habit of regular inspection and timely maintenance.
Automobile air filter is a device to remove particulate impurities from automobile air. Automobile air conditioning filter can effectively reduce the pollutants entering the automobile through HVAC system and prevent the inhalation of harmful pollutants. The automobile air filter is installed in front of the carburetor or air inlet to filter the air entering the automobile engine. The automobile engine needs to inhale a lot of air in the whole running process, and there are many dust particles in the air. If the air filter is not filtered, it will lead to accelerated damage of the piston rod group and cylinder. If very large particles enter between the piston rod and the cylinder, it will cause the engine to pull the cylinder. Automobile air filter also has the function of filtering out dust and impurities in the air and ensuring that a certain amount of clean and dry gas is added into the cylinder. To sum up, the air filter needs to be replaced once every 15000 km or 12 months.
