What Are the Different Types of Air Filters For Cars?

Air filters are an important part of a car’s engine and directly affect its performance on the road. The purified air enters the engine together with the fuel. Air filters should be kept clean and you should replace them after certain mileage. They are mostly made from woven fabric and fiber so it is easy to remove the dirt and other particles from them. It is important to remove these particles from the air filter as they can be very harmful to the engine of your car.

Mainly there are 3 types of air filters available for cars and here is a brief description of them.

Paper Filters: These types of air filters are the most in use because of their affordability. They are suitable for the smaller cars and in areas where dust and pollution is at minimum. Small dust particles present in the air get stuck in them during the filtration process and clean air is passed through to the engine. They are not reusable and have to be replaced after certain mileage.

Cleanable Filters: These are a bit expensive compared to the paper filters but their efficiency counterbalances their cost. These are cleanable and will reduce the replacement costs to a great extent. The big particles that get under the hood of the car are seized while the oil drenched filter catches the smaller particles. If you use these types of filters in your car then make sure you clean them frequently and keep them oiled to increase the efficiency and performance of the car.

The Oil Bath Filters: They are the least efficient among all the types of air filters. Oil bath is used to capture and seize the big particles in the air that can cause damage to the engine if they reach it. If you install air intake in your car then the dust particles that get through the air intake filter will be eliminated by this oil filter.

Stock cars have a complex system of pipes attached to the air filters and the bends in those pipes reduce the flow of the air. Manufacturers do this to reduce the ambient sound but it greatly reduces the fuel efficiency of the engine and puts unnecessary load on your pocket. Aftermarket air filters have eliminated this problem and now you can choose an air filter for your car that suits your requirements and budget.

An air car filter will prolong the life of the engine as harmful particles will be eliminated from the air. This is different than the air intake systems which separate the dust and other particles but cause the wear and tear of the engine. Some air filters have their mileage marked on them so you should replace them before time and should clean them every now and then. A horse with healthy lungs always does well in the race and it is true for your car too as you will not want it to cough on the road.
