Original MANN-FILTER Interior Filter CUK 3448 – Pollen filter with active charcoal – For passenger cars

MANN‑FILTER Interior Filter CUK 3448

The Original MANN‑FILTER Interior Filter CUK 3448 is a high‑performance pollen filter designed specifically for passenger cars. It combines advanced filtration media with an active charcoal layer to deliver clean, fresh air inside the vehicle cabin.

Key Features

• Pollen Filtration: The core of the filter is a dense, high‑efficiency medium that captures pollen grains and other airborne particles down to 0.5 µm.
• Active Charcoal Layer: Integrated charcoal adsorbs volatile organic compounds (VOCs), odors, and harmful gases, ensuring the cabin air remains breathable and odor‑free.
• Durable Construction: The filter housing is made from robust polypropylene, resistant to moisture and temperature variations typical in automotive environments.
• Easy Installation: Designed for quick replacement without special tools. The filter fits snugly into the standard cabin air filter compartment found on most passenger cars.
• Long‑Lasting Performance: Engineered to maintain filtration efficiency over extended periods, reducing the need for frequent replacements compared to conventional filters.

Design and Materials

The CUK 3448 features a multi‑layer structure: an outer protective layer, a middle high‑efficiency filter medium, and an inner charcoal layer. This arrangement ensures that large particles are trapped early, while finer pollutants and gases are absorbed deeper within the filter.

All components are manufactured in accordance with MANN‑FILTER’s strict quality standards, guaranteeing consistent performance across all units. The use of high‑grade polypropylene prevents degradation from exposure to cabin humidity and temperature fluctuations.

Compatibility

The filter is specifically engineered for a wide range of passenger vehicles, including models such as the Peugeot 206, Citroën C3, and other cars within the PSA group. Its dimensions match the standard cabin air filter slots found in these vehicles, ensuring a perfect fit.

Benefits for Vehicle Owners

• Improved Cabin Air Quality: By removing pollen, dust, and odors, occupants experience a cleaner, more comfortable environment.
• Reduced HVAC System Load: A clean filter allows the heating, ventilation, and air conditioning (HVAC) system to operate efficiently, potentially extending its lifespan.
• Health Advantages: The charcoal layer helps neutralize allergens and irritants, benefiting passengers with respiratory sensitivities.
• Environmental Impact: High filtration efficiency means fewer particles are released into the atmosphere, contributing to lower overall emissions from the vehicle’s exhaust system.

Installation Guide

1. Locate the cabin air filter compartment, typically behind the glove box or under the dashboard on the passenger side.

2. Open the compartment cover and remove the old filter. Dispose of it responsibly.

3. Align the new CUK 3448 with the airflow arrows indicated on the housing.

4. Insert the filter until it clicks into place, ensuring a snug fit.

5. Close the compartment cover and secure any fasteners.

6. Start the vehicle to verify proper operation of the HVAC system.
