The Subaru Outback air filtration system is designed to improve the quality of air in the cabin of the car. Replacing the filter will also allow the air from the vents and the A/C to move more freely throughout the vehicle. It's recommended that you change your air filter once a year, or every 7,500 miles (12,100 km). The following steps outline how to change the filter, and only a few simple tools are needed for the project.

    How often should you change a cabin filter? I had one put in six months ago and was recently told I need a new filter. Does this sound right? We don't do a lot of driving.

    Most manufacturers recommend cabin air filters be replaced every 15,000 - 30,000 miles, depending on driving conditions. If someone drives a lot in dusty conditions, they should replace more often.
