These filters in cars need to be cleaned and replaced regularly.
Often likened to the "lungs" of a car, the engine air filter, air conditioning filter, and oil filter need to be cleaned and replaced regularly to ensure the vehicle runs smoothly.

| Depending on how the car is used, each filter needs to be cleaned or replaced periodically. |
Most modern cars are equipped with air conditioning filters, engine oil filters, and fuel filters to minimize debris, dirt, and other contaminants that hinder the circulation of air, oil, and fuel in the vehicle.
Depending on the environmental conditions in which the car is used, each filter needs to be cleaned or replaced periodically to help the engine, air conditioning system, etc., function smoothly. However, not all drivers understand the importance and the appropriate time to clean and replace the filters in their cars.
Engine air filter
The air filter is usually located in the engine compartment under the hood. Its role is to filter dust and dirt from the air before it enters the engine's combustion chamber. After a period of use, dust and moisture accumulate on the filter membrane, clogging the filter's air passages. If not cleaned or replaced, this will obstruct the amount of air entering the engine, causing an imbalance in the air-fuel ratio, resulting in reduced power, engine overheating, and carbon buildup in the combustion chamber.
The engine air filter system should be cleaned regularly after every 5,000 km of vehicle operation, and replaced with a new one after 20,000 km. |
Therefore, as recommended by manufacturers, car users should regularly clean the engine air filter system after every 5,000 km of driving and replace it with a new one after 20,000 km. For older cars, especially those frequently used in dusty environments, the air filter should be cleaned every 3,000-4,000 km and replaced after 15,000 km. Additionally, the air filter system should be regularly inspected; if any damage, moisture, or other issues are detected, it should be replaced with a new air filter.
The air filter is located in the engine compartment, and removing and installing this part is quite simple, so car owners can check, clean, or replace the air filter themselves without having to take their car to a garage.
Engine oil filter
Often referred to by car owners as the "oil filter cup," this compact component plays a crucial role in filtering out dirt and impurities from engine oil, ensuring proper lubrication of the engine's internal parts.
It is advisable to check the engine oil level and replace the oil filter every 10,000 km. |
Unlike air filters, engine oil filters cannot be cleaned and must be replaced periodically after a period of use. Most car owner's manuals advise checking the engine oil level and replacing the oil filter every 10,000 km.
To avoid neglecting this part, some experienced car owners often replace the oil filter after every two engine oil changes. If the oil filter is damaged, it should be replaced to avoid affecting the engine lubrication process.
On some car models, the oil filter housing is located under the engine, so careful installation is necessary to prevent leaks during replacement. Additionally, it's advisable to choose genuine, high-quality oil filters and thoroughly research your engine's technical specifications to select the appropriate filter.
Air conditioning system filter
Similar to the engine air filter, the air conditioning system filter, also known as the cabin air filter, plays a role in filtering out dust and dirt, cleaning the air before it passes through the air conditioning system into the car's interior.
Inspect and clean the vehicle after approximately every 5,000 km of use, and replace the parts after 20,000 km. |
During use, dust and dirt accumulate on the air filters, reducing the airflow into the air conditioner in outside air intake mode, affecting the cooling time of the interior. In addition, exposure to ambient air causes the air filters to become damp and moldy, becoming a breeding ground for various bacteria. The air passing through the filter carries mold and mildew, creating unpleasant odors… affecting the health of those inside the vehicle.
For this part, car users should pay attention to checking and cleaning it after approximately 5,000 km of use, and replacing it after 20,000 km. During use, if you notice a decrease in airflow through the air conditioner, the fan system making strange noises, or an unpleasant odor, you should check and replace the air conditioner filter.
Fuel filter
Along with air filters and engine oil filters, fuel filters are a crucial component that helps remove dirt and rust from the gasoline and diesel fuel pumped into the vehicle. This ensures a clean fuel supply before it enters the engine's combustion chamber.
Fuel filters, also known as gasoline filters or diesel filters, are made from standard paper, a mixture of cellulose, synthetic fibers, and fiberglass. On some vehicles, this component is usually located under the vehicle, near the engine under the hood, or inside the fuel tank. Gasoline and diesel sold on the market pass through the fuel filter before entering the engine to be burned.
During use, if the fuel filter becomes clogged with dirt or damaged, it will block the fuel flow to the carburetor or injectors, causing the engine to have difficulty starting, stuttering, and unstable operation. Given the current quality of gasoline and diesel fuel, users should regularly take their vehicles to an auto service center for fuel filter inspection and cleaning. The fuel filter should be replaced after approximately 40,000 km of use.
