Are Air Filters and Cabin Air Filters the Same?

[VonHarmony]

Air filters and cabin air filters are not the same. The air filter is used to filter the air entering the engine, removing dust and particles, while the cabin air filter is used to filter the air in the air conditioning system, such as when the AC or outside air circulation is on, removing dust and pollen. Below are the relevant details: 1. The function of the air filter is to finely filter the air entering the engine cylinders, ensuring that sufficient and clean air enters the cylinders. Its cleanliness and unobstructed condition are crucial to the engine's lifespan. Generally, it should be replaced every 10,000 kilometers or about six months. If the vehicle is used in areas with severe smog or willow catkins, it is recommended to replace it every three months. 2. The function of the cabin air filter is to filter the air entering the vehicle cabin from the outside, improving air cleanliness and providing a good air environment for passengers, thereby protecting their health. Under normal circumstances, it is recommended to replace it every six months, but this can be adjusted based on the external driving environment. If the environment is relatively humid or prone to smog, the replacement interval can be shortened appropriately.
