How Often Should You Replace the Car Air Filter?

The car air filter should be replaced approximately every 15,000 kilometers. The replacement steps are as follows: 1. Open the car engine hood and locate the position where the air filter is installed; 2. Use a screwdriver to open the air filter protective cover; 3. Remove the old air filter from the car and install the new one. The air filter, also known as an air cartridge or air cleaner, is a type of filter installed in front of the carburetor or intake pipe. It functions to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinder. Air filters can be categorized by their filtration principles into: filtration type, centrifugal type, oil bath type, and composite type.

The replacement interval for car air filters varies from person to person. With 20 years of driving experience, I generally recommend changing it every 12 months or approximately 12,000 kilometers. Based on my experience, in suburban road conditions with more dust, it's advisable to shorten the interval to 8 months or 10,000 kilometers for inspection. A dirty filter can affect engine air intake, leading to increased fuel consumption in mild cases and severe engine wear requiring major repairs in worse scenarios. I usually have the mechanic check it during routine maintenance to save money and hassle. If you're unsure about replacing it yourself, it's better not to attempt it to avoid damaging the clips. Ultimately, following the vehicle's manual recommendations is best, as keeping the filter clean benefits long-term car condition. Additionally, using the recirculation mode less often on days with poor air quality can help extend its lifespan.

I enjoy DIY car maintenance in my spare time. Replacing the air filter is quite simple—I usually inspect it myself every 15,000 km. If it's heavily soiled or blackened, I just buy a new one (cheap replacements cost only a few dozen RMB on Taobao), saving the hassle of visiting a shop. Driving conditions matter: in dusty urban traffic, I check every six months, while highway driving allows longer intervals. Remember, a clogged filter strains the engine and dulls throttle response. I always keep a spare at home for quick swaps—convenient and reassuring. Avoid over-cleaning old filters, as they may tear and let dust into the engine. Just maintain regular inspection habits.

The replacement of the air filter depends on the specific environment. Driving in a first-tier city with heavy air pollution, I usually replace it every 8,000 kilometers or so. Otherwise, excessive dust can clog the engine intake, increasing the engine's burden and raising fuel consumption. The general recommendation is every 12,000-15,000 kilometers or 12 months, but in rainy, humid seasons or areas prone to sandstorms, it can be replaced earlier. A dirty filter can cause a slight drop in power, and the engine sound becomes rougher at idle. When I replace it, I also check the cabin air filter to save time. If the budget is tight, a universal type is sufficient and won't affect overall performance. Daily attention should be paid to ensuring the car's vents aren't blocked by leaves, as maintaining smooth airflow is crucial.

From an economic perspective on air filter replacement intervals, as a budget-conscious ordinary car owner, I typically replace it every 14,000 kilometers. Opting for mid-range branded products costing 20-30 RMB can extend its lifespan. If driving in cleaner environments like suburban roads, I can stretch it to 20,000 km; but in dusty areas, frequent replacement is necessary. A clogged filter increases engine load and fuel consumption. Regularly checking dust accumulation by removing it helps decide when to act. A money-saving trick is occasional light tapping to remove dust, but avoid overdoing it to prevent damaging the mesh. It's advisable to refer to the maintenance manual and not exceed recommended periods, ensuring safe driving while saving costs without harming the car. Paying attention to the connected air conditioning system can reduce overall maintenance expenses.
