• Durable Construction: Made from reinforced polypropylene housing, the filter resists moisture absorption and structural degradation under harsh operating conditions.
• Optimized Airflow: The design balances filtration efficiency with minimal pressure drop, preserving HVAC performance even after extended use.
• Easy Installation: A snap‑fit mounting system allows for quick replacement without the need for specialized tools.
• Compatibility: Specifically engineered to fit the cabin air intake of Mercedes‑Benz Actros MP2, MP3, MP4 models and other similar truck platforms.

Benefits for Truck Operators

• Enhanced Driver Comfort: By filtering out pollen, dust, and other irritants, the cabin remains a healthier environment, reducing fatigue and improving focus.
• Reduced HVAC Wear: Cleaner air reduces particulate buildup on blower components, extending the life of fans and compressors.
• Consistent Air Quality: The filter’s high efficiency ensures that even in dusty or polluted routes, cabin air remains within acceptable standards.
• Low Maintenance Footprint: The snap‑fit design allows for rapid replacement during routine service intervals, minimizing downtime.

Installation Guide

1. Locate the Cabin Air Intake: On most Mercedes‑Benz Actros models, this is situated behind the driver’s seat, near the HVAC control panel.
2. Remove the Old Filter: Slide the existing filter out of its housing. Dispose of it according to local environmental regulations.
3. Prepare the New Filter: Unpack the CU 3869 and ensure that the protective seal is intact.
4. Insert into Housing: Align the filter’s mounting tabs with the corresponding slots in the housing. Push firmly until the snap‑fit mechanism clicks into place.
5. Verify Seal Integrity: Check for any gaps or misalignments that could allow unfiltered air to enter.
6. Test Airflow: Turn on the HVAC system and confirm that airflow is steady and free of unusual noises.

Maintenance Tips

• Inspect the filter at least once every 12,000 km or annually, whichever comes first.
• If you notice a significant drop in cabin air quality or HVAC performance, replace the filter immediately.
• Avoid forcing the filter into place; if resistance is felt, double‑check alignment to prevent damage.
