The four types of filters on a vehicle refer to oil filter, fuel filter, air filter and air conditioner filter. Their replacement frequency may vary with vehicle models, vehicle conditions, and driving habits. The following are general recommendations for their replacement:

1. Oil filter: It is recommended that an oil filter should be replaced together with oil. The oil replacement cycle is typically 5,000 to 10,000 kilometers of mileage.

2. Fuel filter: It is recommended that a fuel filter should be replaced after every 20,000 kilometers of mileage. The replacement cycle of fuel filters used for some models may be longer. Please refer to the vehicle manuals for details.

3. Air filter: It is recommended that an air filter should be replaced after every 10,000 to 20,000 kilometers of mileage or inspected once a year, especially if it is often used in a dusty environment.

4. Air conditioner filter: It is recommended that an air conditioner filter should be replaced after every 10,000 to 20,000 kilometers of mileage. The replacement cycle may be adjusted appropriately depending on operation frequency and air quality.
