Interior Air Quality Maintenance – How Often?

Car Maintenance


How clean is the air inside your vehicle?

Cabin air filters trap dust and particles from getting into your car through your vehicle’s ventilation system.

When these filters are plugged they slow down the airflow into your cabin and impede the heating and A/C systems from functioning properly. Interior air quality may also be reduced and unpleasant odors can arise. Depending on road and air conditions, your cabin air filter will usually require replacement every 25,000 to 50,000 kilometers. Most cars built during the past decade have them.
