Car Filters: The “Four Great Guardians” of Vehicle Health

Car filters are the core protective components of a vehicle, mainly divided into four types, each with its own responsibility. The air filter filters impurities in the intake air to protect the engine from wear; the oil filter purifies the engine oil to prevent sludge from damaging the engine; the fuel filter removes impurities from the fuel to ensure combustion efficiency; and the cabin air filter blocks dust and odors to protect the health of those inside the vehicle.

They need to be replaced regularly. Under normal driving conditions, replace the air filter every 15,000–20,000 km, the oil filter together with the engine oil, the fuel filter every 30,000–50,000 km, and the cabin air filter every 6,000–10,000 km. The replacement interval should be shortened in harsh environments to maintain vehicle performance and reduce maintenance costs.
