Key Features of the CU 3461 Cabin Air Filter

High‑Efficiency Filtration: The CU 3461 employs a multi‑layer media system engineered to capture particles as small as 0.3 µm, ensuring that only clean air reaches the vehicle’s ventilation system.

Improved Cabin Comfort: By trapping allergens, pollen, and fine dust, the CU 3461 helps maintain a healthier interior environment, reducing irritation for drivers and passengers alike.

Compatibility Overview

The CU 3461 is engineered to fit a wide range of passenger vehicles. Below are some of the most common models that use this filter:

• Mercedes‑Benz C‑Class (W203, S203, CL203, C209, A209)

Installation Guide

1. Locate the Cabin Air Filter Compartment: In most passenger cars, this is situated behind the glove box or under the dashboard on the passenger side.
2. Open the Cover: Remove any screws or clips holding the filter housing in place. Gently lift the cover to expose the old filter.
3. Remove the Old Filter: Pull the worn filter out of its slot, taking care not to spill any debris into the ventilation system.
4. Insert the CU 3461: Align the new filter with the airflow arrows and slide it into place. Ensure that it sits flush against the housing walls.
5. Secure the Cover: Replace the cover, re‑tighten any screws or clips, and verify that the filter is firmly seated.

After installation, turn on the vehicle’s HVAC system to confirm proper airflow. The CU 3461 should provide a noticeable improvement in air quality and cabin comfort.

Performance Benefits

• Enhanced Air Quality: By filtering out pollen, dust, and other particulates, the filter reduces allergens that can trigger respiratory issues.
• Reduced HVAC Load: Cleaner air means less strain on the heating, ventilation, and air‑conditioning system, potentially extending its lifespan.
• Improved Fuel Efficiency: A well‑maintained cabin filter allows the HVAC system to operate more efficiently, which can have a minor but measurable impact on fuel consumption.

Maintenance Tips

While the CU 3461 is designed for long service life, regular inspection is recommended. Check the filter every 12–15 months or after driving in heavily polluted environments. Replace it if you notice a significant drop in airflow or if the filter appears visibly clogged.
