Mann Filter cabin air filter CU 25 002 for Mercedes-Benz GLC/C/GLS — OEM-fit, multi-layer particle protection

The MANN-FILTER CU 25 002 is a direct-fit cabin air filter engineered to trap dust, soot and pollen while protecting the HVAC system in many Mercedes-Benz models.

This premium cabin filter replaces the factory part with original-equipment quality from MANN+HUMMEL, reducing airborne particles entering the passenger compartment and helping prevent debris buildup in the heating and air conditioning system. It’s designed for annual replacement under normal conditions and more frequently in dusty or polluted environments. Use vehicle fitment tools to confirm compatibility before purchase.

How does this filter improve in-cabin air quality?

The CU 25 002 captures fine particulates and common road pollutants that otherwise circulate through the ventilation system. While not a medical device, it reduces visible dust and typical urban contaminants, contributing to a fresher-feeling interior.

• Multi-layer filter media traps dust, pollen and soot
• OEM-grade sealing minimizes unfiltered bypass air
• Consistent airflow to avoid reduced vent performance

Will this part fit my Mercedes-Benz model?

This MANN-FILTER is specified for many Mercedes-Benz vehicles — including C-, E-, GLC-, GLE- and GLS-class years listed by the manufacturer — but fitment is vehicle-specific. Always verify with the car’s year and model or use the seller’s fitment checker to ensure correct replacement.

• Fits numerous Mercedes-Benz C 180/C 300, GLC 300, GLE and GLS variants
• Compatible with both gasoline and diesel trims listed by MANN-FILTER
• OEM-style shape and mounting points for direct replacement

How often should I replace the cabin air filter?

MANN-FILTER recommends replacing this cabin filter about once every 12 months under normal driving conditions. In areas with heavy dust, pollen seasons, or frequent urban pollution, shorter intervals improve cabin air and HVAC longevity.

• Standard guidance: replace every 12 months or at manufacturer service intervals
• Replace sooner if you notice reduced airflow, odors or visible contamination
• Inspect during routine service or when changing engine air filters

Is installation difficult or do I need special tools?

Installation is straightforward on most covered Mercedes models and typically requires only basic hand tools or none at all. The filter is designed for an exact fit so it aligns with the factory housing and seals without modification.

• OEM-fit dimensions for easy drop-in replacement
• Simple access in glovebox or under-hood locations depending on model
• Follow vehicle-specific instructions for proper seating and orientation

Who is this for: The MANN-FILTER CU 25 002 is aimed at Mercedes-Benz owners who want an OE-quality cabin air filter to maintain interior comfort and protect HVAC components. It suits drivers of C-, E-, GLC-, GLE- and GLS-class cars listed by the manufacturer, fleet managers and DIY mechanics seeking a reliable, straightforward replacement part that preserves factory performance.
