Compatibility Overview

The CU 23 011 filter is engineered to match the interior air filtration requirements of a wide range of passenger vehicles. While it is specifically tailored for certain Nissan models, its design allows it to be used in many other cars that share similar HVAC architecture.

For a definitive fitment check, consult your vehicle’s service manual or the MANN‑FILTER compatibility chart available on the manufacturer’s website.

Installation Guide

1. Locate the Cabin Air Filter Compartment: In most passenger cars, this is situated behind the glove box or under the dashboard near the steering column.
2. Open the Cover: Release any clips or screws holding the filter housing in place. Gently lift the cover to expose the old filter.
3. Remove the Old Filter: Pull it straight out, taking note of its orientation (usually marked with a directional arrow).
4. Insert the New CU 23 011 Filter: Align the filter’s airflow direction arrow with the vehicle’s airflow path. Slide it in until it clicks into place.
5. Secure the Housing: Replace the cover and re‑attach any clips or screws. Ensure a snug fit to prevent air leaks.
6. Test the System: Start the vehicle, turn on the HVAC system, and verify that airflow feels normal and no unusual noises are present.

Maintenance Tips

• Check the filter every 12–15 months or after heavy exposure to dust and pollen (e.g., during springtime).
• Avoid forcing air through a clogged filter; this can reduce HVAC efficiency and increase cabin temperature.
• Store spare filters in a dry, cool place to preserve the integrity of the filtration media.
