Design and Construction Details

The CU 2951 features a multi‑layer media system that combines an outer pre‑filter layer to capture larger debris with an inner high‑efficiency filter capable of trapping microscopic particles. The filter housing is constructed from robust, heat‑resistant plastic that protects the media during operation and prevents moisture ingress.

Performance Characteristics

Testing demonstrates that the CU 2951 achieves a filtration efficiency of up to 99% for particulate matter in the size range of 0.5 µm to 10 µm. This performance level ensures that allergens, pollen, and fine dust are effectively removed from the air supplied to the cabin.

Installation Procedure

1. Locate the Cabin Air Filter Compartment: The filter is typically positioned on the passenger side of the engine compartment, beneath the plenum chamber cover. Refer to your vehicle’s service manual for exact location.
2. Remove the Cover: Unscrew or unclip the protective cover that shields the filter housing.
3. Extract the Old Filter: Gently pull out the existing filter, taking care not to damage the surrounding components.
4. Insert the New CU 2951: Place the new filter into the housing, ensuring that it sits flush and aligns with the mounting tabs or clips.
5. Reattach the Cover: Secure the protective cover back onto the housing to complete the installation.

Maintenance Tips

• Check the filter every 12,000–15,000 miles or as recommended by your vehicle manufacturer.
• Replace the filter if you notice a noticeable decline in airflow through the ventilation system.
