What is the replacement interval for an air filter?

[LeMaya]

Air filters should be replaced every 15,000 kilometers, while vehicles operating in harsh environments should have them replaced no later than every 10,000 kilometers. The service life of air filters is 30,000 kilometers for passenger cars and 80,000 kilometers for commercial vehicles. The function of an automotive air filter is to purify the air entering the engine combustion chamber by removing particles and impurities, ensuring clean air intake for the engine. The filter element is the main filtering component responsible for gas filtration, while the housing provides necessary external protection for the filter element. The operational requirements for air filters include performing high-efficiency air filtration without significantly increasing airflow resistance and maintaining continuous operation over extended periods.
