Most Mercedes-Benz cars and SUVs have two types of air filters -- one for their engines and one for their cabins. That's true whether you drive a crossover like the Mercedes-Benz GLE 350, a sedan such as the Mercedes-Benz C 300 or E 350, or otherwise. Both capture airborne contaminants, before they can get into engine parts, the heater, and air conditioning parts, respectively.

Unfortunately, sooner or later, the pollutants that collect can restrict airflow through both of them -- that is, if they don't otherwise degrade from age. When either of these things happens, engine problems and car HVAC malfunctions follow.

The best way to tell if the air filter in your Mercedes-Benz vehicle needs replacing, then, is to look for the signs. They include a lit Check Engine light on the dashboard, a dirty, blocked, or worn-out filter, and unclean smells in the cabin. Others range from unusual engine noises and misfires to loss of engine power, weak throttle response and acceleration, and worsening fuel economy. You may even experience emissions increases.

If you see any such symptoms, your car air filters probably need changing. Otherwise, they'll need replacing regularly, about every 12,000 to 15,000 miles, or every 30,000 miles at most. There are clear benefits to replacement sooner, namely, maintaining fuel efficiency, emissions control, and helping your engine last longer. Review your owner's manual for more details.
