Replacing the cabin air filter on your Mercedes-Benz GLB is a simple maintenance task that helps ensure clean air inside your vehicle. A clogged or dirty filter can reduce airflow, cause unpleasant odors, and affect the efficiency of your HVAC system.

When to Replace the Cabin Air Filter

Mercedes-Benz recommends checking the cabin air filter every 15,000 miles or once a year. However, if you frequently drive in dusty or polluted environments, it’s a good idea to inspect and replace the filter more often.

Tools and Materials Needed

  • Replacement cabin air filter compatible with the Mercedes-Benz GLB
  • Flathead screwdriver or trim removal tool
  • Clean cloth

Step-by-Step Instructions

  1. Locate the filter housing: The cabin air filter is behind the glove box on the passenger side.
  2. Open the glove box: Remove any contents and gently lower the glove box by releasing the stops on each side.
  3. Remove the filter cover: Use a flathead screwdriver to carefully unclip the filter cover.
  4. Take out the old filter: Pull the old cabin air filter straight out, noting the airflow direction indicated by arrows on the filter.
  5. Insert the new filter: Slide the new filter into place, ensuring the airflow arrows are pointing in the correct direction.
  6. Reassemble: Replace the filter cover, lift the glove box back into position, and secure the stops.
  7. Test the system: Turn on your air conditioning or heating to confirm proper airflow and fresh air circulation.

Regular replacement of your cabin air filter keeps your Mercedes-Benz GLB’s interior air fresh and helps maintain optimal HVAC performance. If you’re unsure about the process or need assistance, consult your Mercedes-Benz service center.
