How do I install the fine particle and dust filters?

Installation is designed to be accomplished with basic tools and minimal automotive experience. The fine particle filter installs behind the glove box and the dust filter slots under the hood; orientation and clips are shown in the reference pictures and instructions.

• Open the glove box, lower or remove retaining clips to access the filter housing.
• Slide the fine particle filter into place with the airflow arrows oriented as shown.
• Replace the under‑hood dust filter in its tray, ensuring a snug fit and secure fasteners.
• Confirm seals and close housings before testing cabin ventilation.

What benefits will I notice after replacing these filters?

Fresh filters help maintain consistent HVAC airflow, reduce visible dust inside the cabin, and can reduce odors and particulates that enter through the ventilation system. While not a medical device, a properly seated filter supports a cleaner cabin environment for occupants.

• Smoother, more consistent blower performance when filters are clear.
• Reduced dust build-up on dash and vents over time.
• Improved seasonal comfort by keeping debris out of the HVAC system.

When should these cabin filters be replaced?

Replacement frequency depends on driving conditions and climate; typical intervals are every 12,000–20,000 miles or once per year for average use. Replace sooner in dusty, pollen-heavy, or urban environments with heavy traffic to maintain ventilation performance.

• Check filters visually during regular service intervals.
• Replace if visibly dirty, blocked, or emitting persistent odors.
• Follow Mercedes service recommendations if provided in your owner’s manual.

Who is this for: This OIFILLIO cabin filter set is intended for Mercedes owners and technicians who need an exact-fit replacement for the factory dust and fine-particle filters on supported C‑class, E‑class and GLC models. It suits DIYers comfortable with basic under-dash and under-hood access, independent service shops, and drivers seeking to maintain HVAC performance and cabin cleanliness without sourcing OEM parts.
