Are the Air Filter and Cabin Air Filter the Same?
2 Answers
Air filters and cabin air filters are not the same. Here is the relevant information: The function of the air filter is to filter particulate impurities in the air, ensuring that a sufficient amount of clean air enters the cylinders and preventing suspended dust in the air from being sucked into the engine, which could cause wear on the piston group and cylinders. The cabin air filter, on the other hand, filters impurities contained in the air entering the vehicle interior from the outside, including tiny particles, pollen, bacteria, industrial exhaust, and dust. It improves air cleanliness, prevents these substances from entering and damaging the air conditioning system, provides a good air environment for passengers inside the vehicle, and also prevents window fogging.
The air filter and the cabin air filter are completely different things. Let me explain clearly. The air filter is responsible for filtering the air entering the engine, blocking dust and small debris to protect the engine internals and prevent issues like insufficient air intake, power loss, or a surge in fuel consumption. It's usually located under the hood, and regular replacement is crucial. I recommend checking it every 10,000–20,000 km; otherwise, the engine's lifespan will shorten. On the other hand, the cabin air filter cleans the air in your car's HVAC system, removing pollen, bacteria, and particles, directly affecting your breathing comfort. It's often located behind the glove box. Don’t neglect it—a dirty filter can make the cabin air stuffy and trigger allergies. Their replacement frequencies also differ: the cabin air filter should be replaced once or twice a year. Confusing them can lead to unnecessary repair costs, so distinguishing them properly can save you a lot of trouble.
