Original MANN-FILTER Interior Filter CUK 2231 – Pollen filter with active charcoal – For passenger cars

MANN‑FILTER Interior Filter CUK 2231

The Original MANN‑FILTER Interior Filter CUK 2231 is a high‑performance pollen filter designed for passenger cars. It incorporates an advanced active charcoal layer that captures fine particles, allergens and odours, ensuring the cabin air remains fresh and healthy.

Key Features

• Dual‑layer construction: A pre‑filter removes larger debris while the main filter uses high‑efficiency media to trap microscopic pollen, dust, and airborne pollutants.
• Active charcoal integration: The charcoal layer adsorbs volatile organic compounds (VOCs) and unpleasant smells, improving overall cabin air quality.
• High airflow capacity: Engineered to maintain optimal ventilation without compromising engine performance or fuel efficiency.
• Durable housing: Made from robust plastic that resists moisture and temperature fluctuations typical of automotive environments.
• Easy installation: Fits standard cabin filter slots in most passenger cars, including a wide range of Mitsubishi models such as Grandis, Lancer, Outlander, and more.

Benefits for Vehicle Owners

The CUK 2231 delivers improved respiratory comfort by filtering out allergens that can trigger asthma or allergies. Its charcoal layer also reduces cabin odours from exhaust gases, food, and environmental pollutants. By maintaining cleaner air, the filter helps preserve interior upholstery and electronic components from dust‑induced wear.

Compatibility Overview

The filter is specifically engineered for passenger cars, with a focus on Mitsubishi models but also suitable for other manufacturers that use the same cabin air filter dimensions. Commonly matched vehicles include:

• Mitsubishi Grandis (NA_W)
• Mitsubishi Lancer (V8_W, V9_W)
• Mitsubishi Outlander (1.3‑2.4 L 16V)
• Mitsubishi Pajero IV (V8_W, V9_W)
• Other passenger cars with compatible filter housings

Installation Guide

1. Locate the cabin air filter compartment: Usually behind the glove box or under the dashboard.
2. Open the housing cover: Release clips or screws that secure the panel.
3. Remove the old filter: Pull it straight out; note its orientation for correct placement of the new unit.
4. Insert the CUK 2231: Align the airflow arrow on the filter with the direction indicator in the housing. Push firmly until it clicks into place.
5. Reassemble the cover: Secure clips or screws, ensuring a tight seal to prevent unfiltered air from entering.
6. Check for proper fit: Verify that no gaps remain and that the filter sits flush within its housing.

Maintenance Tips

• Replace the filter every 12,000–15,000 km or annually, whichever comes first, to maintain optimal airflow.
• If you drive in dusty or polluted environments, consider a more frequent replacement schedule.
• Inspect the housing for cracks or damage before each installation; replace if necessary.
