What is the purpose of a car air filter?

The purpose of a car's air filter is to prevent dirt and other particles from entering the fuel system or engine. Air filters also prevent particles from entering the air conditioner system.

Air filters are essential in ensuring quality performance in vehicles. These components need to be changed on occasion as dirt and debris begins to build up. Once the filter becomes clogged, it can cause performance issues. Different makes and models of vehicles require different sizes of filters and carbon air filters are available. Carbon air filters capture more than just dirt and debris as they also prevent allergens and other contaminants from entering the vehicle.
