If you drive a Mercedes-Benz vehicle, the cabin dust/combination filter is replaced during Service B*. The first visit for Service B occurs at approximately 20,000 miles or 1 year after the previous service, and then at approximately 20,000 miles or 2 years after that.

What Does A Cabin Air Filter Do?

A cabin air filter cleans the air entering your vehicle’s ventilation, heating, and air conditioning systems. This, in turn, prevents dirt, pollen, dust, and other pollutants from entering your cabin, so you and your passengers can stay comfortable on your drives around Plymouth. A properly working filter is especially crucial if you have allergies or live in an area with poor air quality. That said, when the filter clogs and becomes less effective, you will need to replace it for it to serve its purpose. 

What Are Signs That You Need To Replace Your Cabin Air Filter?

Besides knowing how often to replace a cabin air filter, you should also be aware of the following signs that your filter is no longer working as effectively: 

• Reduced airflow when your climate control systems are on
• More dust than usual is settling on your vehicle’s surfaces
