When to Replace the Air Filter Element and Cabin Air Filter?
3 Answers
The air filter element should be replaced every 15,000 kilometers and cleaned every 5,000 kilometers. The cabin air filter should be replaced every 20,000 kilometers and cleaned every 10,000 kilometers. The functions of the cabin air filter are: 1. To ensure clean air in the passenger compartment, preventing bacterial growth and creating a healthy environment; 2. To effectively separate solid impurities such as dust, powder, and grinding particles from the air; 3. To effectively block pollen, ensuring that drivers and passengers do not experience allergic reactions that could affect driving safety. The air filter element is a type of filter, also known as an air filter cartridge or air cleaner, used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms.
I've been driving for over ten years and changing the air filter and cabin air filter is something I do quite often. The air filter is responsible for engine intake; if it's clogged, it can affect the car's performance and fuel consumption. Generally, it should be replaced every 10,000 to 15,000 kilometers. Since I often drive in rural areas with more dust, I change it more frequently, at most every 10,000 kilometers. The cabin air filter filters the air inside the car. If you notice a musty smell or weak airflow when using the AC, it's probably time for a replacement. I usually change it once a year to prevent my family from breathing in dust. It's best to check it during humid weather to avoid mold growth, which can make things worse. Remember, regular maintenance keeps your car running smoothly—don't wait until strange noises appear. It saves both money and hassle.
As someone who enjoys DIY car maintenance, changing the filters is a breeze. The air filter is located in a box under the hood—just open it up and replace if it looks dirty. For normal driving, check it every 12,000 km or so, but if you frequently drive near construction sites with heavy dust, shorten the interval to 8,000 km. The cabin air filter sits behind the glove compartment under the windshield, making it easy to inspect. If airflow weakens or you notice odd smells, it’s time for a change—I recommend replacing it every 10,000 km or annually. Swapping it takes just 10 minutes with a new filter, and afterward, the AC cools noticeably faster. Sticking to this routine prevents minor issues like engine sluggishness or allergy-triggering dust from vents. Bottom line: regular checks beat costly repairs down the road.
