How Often Should the Cabin Air Filter Be Replaced in a New Car?

Here are the details regarding the replacement of the cabin air filter in a new car: 1. The cabin air filter should typically be replaced every 15,000 kilometers or once a year. However, the exact replacement interval depends on the vehicle's usage and driving conditions. If the car is frequently driven in dusty or heavily polluted areas, the replacement interval should be shortened. 2. As the car is driven over time, many components require replacement. The cabin air filter itself becomes contaminated after prolonged use, accumulating dust and bacteria both inside and out, necessitating timely replacement. Additional information about the cabin air filter: 1. The cabin air filter is usually located under the hood, on the side of the engine, positioned in front of the carburetor or intake pipe, connected via a duct. Open the hood to locate the air filter housing. 2. Some filter housing covers are secured with screws and can be removed using a screwdriver, while others have clips and can be opened directly. Remove the old cabin air filter and clean the filter housing, wiping the interior and exterior with a clean cloth. Install the new cabin air filter in the correct orientation, ensuring it is placed properly. Finally, reattach the filter housing cover.

This is a common question we get at our repair shop. Typically, new cars don't need an AC filter replacement in their first year - the factory-installed one can usually last around 10,000 kilometers. The key factor is your driving environment: if you frequently drive through construction sites or dusty northern areas, you might need to check it at 7,000-8,000 km. A simple test is to turn on the AC and smell - if there's an earthy odor or reduced airflow, it's time for replacement. Personally, I change my car's filter every other maintenance service, roughly every 1.5-2 years, though in southern regions with cleaner air it might last longer. Remember, don't just go by time - the filter's actual condition matters more than mileage.
