What is the Air Filter and How Does it Work?

The air filter is an essential emissions component that helps ensure peak engine performance. For every gallon of gasoline burned, an engine takes in about 9,000 gallons of air. The air filter traps airborne contaminants like dirt and dust, and keeps them from getting into the engine’s moving parts. Without the air filter, these contaminants would cause excessive wear to the engine’s moving parts, and reduce fuel economy. A clean air filter also allows the correct mixture of air and fuel, helping to increase your gas mileage and engine performance.

Air Filter Replacement

The air filter is removed and inspected. If its condition indicates replacement, a new air filter is installed.

How Often to Replace Your Air Filter

Owner’s manual recommendations vary based on your driving conditions. The general guideline is to change your air filter when it’s no longer translucent or appears dirty, and can no longer do an effective job.

What is the Cabin Air Filter and How Does it Work?

Many vehicles today are equipped with a climate control system in the passenger cabin, which cleans incoming air during the heater, air conditioner, and vent modes. The system includes a cabin air filter to help remove dust, pollen, mold spores and other particles from the air you breathe inside your vehicle. This is especially beneficial in certain driving conditions, like dusty roads, city driving, and industrial areas. The cabin air filter is also responsible for adequate airflow into the passenger cabin. Over time, the cabin air filter becomes clogged or dirty, and those that come with an electrostatic charge become depleted, reducing airflow into the passenger cabin. If not replaced, the heater and air conditioner cores could eventually be damaged by corrosion.
