The engine air filter protects the GLS engines intake air for combustion; the cabin air filter cleans the air you breathe through the HVAC system.

Both filters matter, but they do different jobs. The engine filter helps maintain power and efficiency by keeping dust out of the intake path. The cabin filter targets pollen, dust, and odors for passenger comfort. Mercedes-Benz of Sudbury installs OEM-spec filters designed for the GLS.

• Engine filter: intake protection, performance
• Cabin filter: HVAC air quality for occupants
• OEM fit: ensures proper sealing and airflow

Typical signs are reduced power or MPG (engine filter) and weak airflow or musty odors (cabin filter).

If the engine filter is dirty, the GLS may feel sluggish or idle roughly. A clogged cabin filter often shows up as diminished vent airflow or lingering odors when you start the HVAC. If you notice these symptoms in Sudbury or Greater Boston, we can inspect both filters and advise next steps; check our service specials.

• Engine: hesitation, rough idle, lower fuel economy
• Cabin: weak fan output, foggy windows, smells
• Visual: darkened/loaded filter media

Cabin filters are available in OEM-spec media, including options designed to capture fine particulates and help reduce odors.
