What is the difference between a car's cabin air filter and engine air filter?

[MacHolden]

Here are the specific differences between a car's cabin air filter and engine air filter: 1. The engine air filter's function is to filter particulate impurities from the air, ensuring sufficient clean air enters the cylinders, and preventing floating dust in the air from being sucked into the engine, which would accelerate wear on piston assemblies and cylinders. 2. The cabin air filter filters impurities from the air entering the vehicle interior, including micro-particles, pollen, bacteria, industrial exhaust, and dust, improving air cleanliness. It prevents these substances from entering the air conditioning system and damaging it, while providing good air quality for vehicle occupants. Here is relevant information about car cabin air filters and engine air filters: 1. The engine air filter should be replaced every 10,000 kilometers or approximately every six months. 2. The cabin air filter should normally be replaced every six months.
