An Article to Help You Understand the Differences Between a Car's Four Filters

1. Oil Filter 

Function: The oil filter cartridge is used to remove impurities, dirt, and metal particles from the engine oil, ensuring the oil remains clean. This protects the internal components of the engine and extends its service life.

Replacement Interval: Typically replaced during an oil change: generally every 5,000 to 10,000 kilometers, but always refer to the vehicle's owner's manual for specific recommendations.

2. Air Filter

Function: The air cartridge filters dust, impurities, and other contaminants from the air entering the engine. This ensures clean air flows into the engine, guaranteeing efficient combustion, enhancing power output, and improving fuel economy.

Replacement Interval: Generally every 10,000 to 15,000 kilometers. However, if you frequently drive in dusty environments, more frequent replacement is necessary.

3. Fuel Filter

Function: The fuel element filter filters impurities and water from the fuel, preventing contaminants from entering the engine's fuel system. This ensures the fuel remains clean and protects the fuel injectors and other fuel system components from damage.

Replacement Interval: It is recommended to replace it every 20,000 to 30,000 kilometers, but the exact timing depends on the vehicle model and usage conditions.

4. Aircon Filter

Function: The air conditioning (AC) filter cartridge filters dust, pollen, smoke, and other pollutants from the air inside the vehicle's cabin. This ensures fresh and clean air inside the car, providing a more comfortable driving experience, especially during periods of high pollution or allergy seasons.

Replacement Interval: Generally every 15,000 to 20,000 kilometers. If you frequently drive in areas with severe air pollution, it should be replaced earlier.
