How to Maintain an Air Filter?
2 Answers
Air filter maintenance methods: 1. Follow the vehicle's maintenance cycle; the air filter should be cleaned and maintained approximately every 5,000 kilometers driven; 2. In areas with high dust or poor air quality, it is recommended to clean it every 3,000 kilometers; 3. Generally, the air filter should be replaced every 20,000 kilometers driven. The main components of an air filter are the filter element and the housing. The filter element is the primary filtering component, responsible for filtering the air, while the housing provides necessary external protection for the filter element. The operational requirements for an air filter include performing high-efficiency air filtration, not adding excessive resistance to airflow, and being capable of continuous operation over long periods.
Over the years of driving, I've always maintained the air filter myself. It acts like a mask for the engine—if clogged, it affects air intake efficiency. I remove and inspect it every 5,000 km, gently tapping off surface dust. If it's oil-stained or blackened, I replace it. When driving in the dusty northwest, I installed a pre-filter to extend its lifespan. Replacing the filter is simple: open the engine bay, locate the filter box, and unclip it—just be careful not to let debris fall into the intake pipe. When choosing a filter, consider the material: cotton ones clog easily but filter finely, while synthetic fibers offer better airflow. Never wash a paper filter with water—it’ll be ruined once soaked!
