Car Filters That Need Regular Replacement

Be proactive in checking and periodically replacing the 4 types of car filters below to ensure safety and health for the user.

Fuel filter

The fuel filter plays an important role in removing dirt and rust in gasoline and diesel. From there, it delivers clean and safe fuel into the combustion chamber. The fuel filter is usually located under the car chassis, near the engine, under the hood, or inside the fuel tank. If the fuel filter is dirty or damaged, it will reduce the car’s performance and prevent the correct air-fuel ratio. Signs that the filter has problems include the car not starting or jerking, strange engine noises, sparks in the exhaust pipe… Therefore, the owner should replace the fuel filter after about 50,000 km or once every two years.

Oil filter

This component is compact in design, with the function of filtering out dirt, excess oil, and sludge to keep the circulating oil inside the car clean. This helps the internal parts operate optimally and prevents rust. The oil filter needs to be replaced periodically after a period of use. According to manuals, the oil filter should be replaced after about 10,000 km. In addition, you should check the oil filter cup every 1–2 months, and if there are signs of damage, replace it in time. Note: purchase genuine oil filter cups that match the manufacturer’s technical specifications to ensure optimal oil filtration.

Engine air filter

This component functions to filter air before it enters the combustion chamber. Therefore, if not replaced periodically, it will obstruct airflow into the engine and distort the air-fuel ratio. Signs of this issue include carbon deposits in the engine and higher-than-normal engine temperatures. This component needs to be cleaned every 5,000 km and replaced after 20,000 km. However, if you are using an old car, the replacement time may be sooner, depending on the vehicle’s operating conditions.

Air conditioning system filter

When the air conditioner is turned on, the system draws outside air, which causes dust to stick to the filter membrane, reducing airflow and leading to harmful outside air entering the car’s cooling system. Moreover, dust, mold, and dead insects also cause unpleasant odors inside the cabin, which, over time, affects the user’s health. Therefore, the owner should clean the AC filter every 5,000 km and replace it after about 20,000 km. During use, if the air conditioner has odors, the filter is ineffective, or the air conditioner does not cool, the driver should check and replace the AC filter.
