Types Of Filters In A Car And Its Importance

Your car has different types of filters for different functionalities. Filters are required for different types of operations in a car whether it is related to engine, fuel, oil or air. Here is a list of the types of filters in a car and their importance.


The air filter in engine cleans the air that goes into the engine for combustion. The air filters are made with different materials like paper, foam or cotton. It cleans the air going into the engine and prevents any dust from entering. It helps in smooth combustion and improves fuel efficiency. As it prevents the dirt, debris, and contaminants from entering the engine better performance is ensured. The engine air filter should be changed every 15,000 to 30,000 miles.


Oil filter makes sure that all the oil transferred to the engine is clean and of good quality. It prevents any abrasive particles from entering the engine that can wear the engine excessively. It also helps improve the efficiency of the car. Oil filter keeps the engine in sublime condition to function quickly and effectively. The oil filter should be changed every 5000 to 7500 miles to keep the engine safe.


It filters the dirt and rust particles from the fuel. The fuel filter is found in the most internal combustion engines. It helps in the smooth running of the fuel pump and the engine as it catches particles, debris, and impurities before entering the fuel tank. It makes sure that the fuel that reaches the fuel pump is clean. The fuel filter change interval varies in different cars, but auto mechanics suggest to get it changed after 20,000 miles.


Cabin air filter cleans the air entering into the interior of a car through air conditioner, heating, and ventilation. It prevents dust and other impurities from entering that can make sitting in a car unpleasant. The cabin air filter is recommended to be changed after 12,000 to 15,000 miles by auto mechanics and mobile mechanics.


The emission filter and emission valve work together to move the toxic fumes created by the engine back to the combustion chambers to re-burn and help increase the fuel efficiency. It also helps to keep the air pollutants down. The emission valve makes sure that engine gets enough air while the emission filter removes the oil vapors.
