How often should the air filter and cabin air filter be replaced?
2 Answers
Car air filters should be replaced approximately every 15,000 kilometers, while cabin air filters should be replaced every 10,000 to 20,000 kilometers or once a year. Below is an introduction to air filters and cabin air filters: 1. The cabin air filter refers to the filter in the vehicle's air conditioning system, whose main function is to purify the air inside the car cabin. It can effectively filter out smoke odors, pollen, dust, harmful gases, and various odors. 2. The air filter refers to the filter in the engine's intake system, whose main function is to filter out impurities from the air entering the engine.
The replacement cycle for air filters and cabin air filters depends on how you use your car. I've been driving for eight years, mainly commuting in the city. The engine air filter usually needs to be replaced every 15,000 kilometers. However, if you frequently drive on highways or in dusty areas, such as around construction sites, it's better to shorten the interval to 10,000 kilometers. The cabin air filter is even more critical—replace it every 12 months, otherwise, the car may develop unpleasant odors. Especially in summer, dirty air blown out by the AC can make people uncomfortable. It's recommended to have a mechanic check it during each maintenance service, or you can inspect it yourself—if it looks black, replace it. Filters cost just a few dozen yuan each. Not replacing them can lead to increased engine fuel consumption, and the AC will be less efficient, wasting more fuel. Developing good habits will make your car run smoother.
