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