The Importance Of Maintaining Your Cabin Air Filter
Not to be confused with the engine air filter, a cabin air filter removes contaminants from the air that goes through the interior ventilation system. It filters dust, pollen, and other problem particles out of the air you breathe while you're driving. The point is to make the driving experience more pleasant, and it's particularly useful if you have allergies or respiratory issues.
The filter service inspects the quality of the cabin air filter and replaces it if necessary. Depending on the vehicle, this can be a simple, five-minute procedure, or it can get more involved. Air filters aren't always easily accessible.
Regardless, most manufacturers recommend replacing the filter every 10,000 to 15,000 miles, or once a year. If you can't remember the last time you dealt with it, then it might be time to schedule service.
Know What Signs to Look For
Cabin air filters bear no impact on engine performance. The car will drive the same whether you have a new or old filter. Instead, this service is about the quality of the drive. Your car won't suffer from ignoring the cabin air filter; you and the passengers will. Aside from improving air quality, the filter helps keep the interior of the vehicle clean. It also reduces the amount of work the vent system has to do to push air.
If you notice persistent bad smells, noisy airflow or a noticeable increase in dust in the vehicle, you're probably overdue for a replacement.
