Why Replace Your Mercedes Cabin Filter?
-
Allergy Season: Spring pollen can overwhelm a saturated filter, recirculating allergens through the cabin
-
Urban Driving: City traffic exposes your cabin to diesel particulates — a carbon filter actively neutralizes these
-
AC Efficiency: A fresh filter allows optimal airflow through the evaporator for maximum cooling
-
Resale: Clean cabin air is a subtle but important factor in maintaining your Mercedes' premium feel
FAQ
Q: Does this fit my 2012 C250?
A: Yes — the W204 C-Class cabin filter housing is identical across all engine variants including the C250 1.8L turbo.
Q: What's the difference between CUK 29 005 and CU 29 005?
A: The CUK version (this product) includes the activated carbon layer for odor absorption. The CU version is a standard particulate-only filter. CUK is the premium option.
Q: How do I reset the cabin filter service reminder?
A: After replacement, the service indicator in the instrument cluster menu can be reset through the steering wheel controls under "Assyst Plus" → "Service" → "Confirm" (procedure varies by model year).
