Original MANN-FILTER Interior Filter CU 22 004 – For passenger cars

Overview of the MANN‑FILTER Interior Filter CU 22 004

The MANN‑FILTER Interior Filter CU 22 004 is a high‑performance cabin air filter designed to keep the interior of passenger cars clean and comfortable. It is engineered for optimal airflow while trapping dust, pollen, and other airborne contaminants that can affect both driver comfort and vehicle ventilation systems.

Key Features

• Advanced Filtration Technology: Utilises a multi‑layer media structure that captures fine particles down to 0.3 µm, ensuring the air inside the cabin remains free from allergens and pollutants.
• Optimised Airflow: The filter’s design balances filtration efficiency with minimal pressure drop, maintaining HVAC performance without compromising comfort.
• Durable Construction: Made from high‑quality synthetic fibers that resist moisture absorption and maintain structural integrity over extended periods of use.
• Universal Compatibility: Fits a wide range of Subaru models including the Forester, Impreza, XV, Levorg, WRX, and many others. The dimensions (H58 mm × L219 mm × W235 mm) are standard for most passenger cars.
• OEM‑Approved: Recognised as an original equipment replacement by manufacturers, guaranteeing the same level of performance as the factory‑installed filter.

Installation Guide

Replacing the cabin air filter is a straightforward maintenance task that can be completed in under 10 minutes. Follow these steps:

1. Locate the Filter Compartment: In most vehicles, the filter sits behind the glove box or beneath the dashboard on the passenger side.
2. Open the Cover: Release any clips or screws securing the compartment door and lift it open.
3. Remove the Old Filter: Gently pull out the worn filter, noting its orientation. The airflow arrow on the old filter indicates the correct direction for the new one.
4. Insert the New Filter: Place the MANN‑FILTER CU 22 004 into the compartment, aligning it with the airflow indicator. Ensure it sits flush against the edges to prevent gaps.
5. Secure the Cover: Close the door and reattach any clips or screws. Verify that the cover is firmly sealed.
6. Test the System: Turn on the vehicle’s HVAC system and check for normal airflow from the vents. A smooth, unobstructed flow confirms proper installation.

Benefits of Using the MANN‑FILTER CU 22 004

• Improved Cabin Air Quality: By trapping pollen, dust, and other irritants, the filter reduces allergic reactions and enhances overall comfort for occupants.
• Enhanced HVAC Efficiency: The low resistance design ensures that heating, ventilation, and air‑conditioning units operate at peak efficiency without excessive energy consumption.
• Extended Component Life: Cleaner air reduces wear on the HVAC system’s blower motor and other internal components, potentially extending their lifespan.
• Consistent Performance: The filter maintains its filtration capability throughout its service life, providing reliable protection from contaminants.

Compatibility Summary

The MANN‑FILTER CU 22 004 is compatible with a broad spectrum of Subaru models and other passenger cars. Below are some representative examples:

Maintenance Tips

• Check the filter every 12,000 to 15,000 miles or as recommended by your vehicle’s maintenance schedule.
• Avoid using compressed air to clean the filter; this can damage the media and reduce filtration efficiency.
• If you notice a significant drop in HVAC performance or an unpleasant odor inside the cabin, replace the filter immediately.
