Original MANN-FILTER Interior Filter CU 2424 – For passenger cars

Overview

The MANN‑FILTER CU 2424 Interior Filter is a premium cabin air filtration solution engineered for passenger cars. Designed to safeguard the vehicle’s interior environment, it captures dust, pollen, and other airborne contaminants, ensuring that occupants breathe cleaner air while maintaining optimal climate control performance.

Design & Build Quality

The filter features a robust polypropylene backing that provides structural integrity and resistance to moisture. Its high‑efficiency media layer is engineered with advanced electrostatic attraction, enabling it to trap particles as small as 0.3 µm. The unit’s dimensions are precisely matched to the standard MANN‑FILTER CU series mounting cavity, guaranteeing a snug fit without gaps that could compromise filtration.

Performance Characteristics

• Pollen Capture Efficiency: Up to 99.9% for particles ranging from 0.5 µm to 10 µm.
• Dust and Debris Retention: Designed to hold up to 200 g of particulate matter before airflow resistance increases significantly.
• Airflow Resistance: Maintains ≤ 0.5 kPa pressure drop under normal operating conditions, ensuring that HVAC systems continue to deliver adequate airflow.
• Odor Reduction: Integrated activated carbon layer neutralizes common vehicular odors such as exhaust fumes and cabin smells.

Compatibility & Vehicle Fitment

The CU 2424 is engineered for a wide range of passenger cars, including models from Renault, Peugeot, Citroën, Opel, Vauxhall, Ford, Volkswagen, Audi, BMW, Mercedes‑Benz, and many others. Its standardized mounting design allows it to replace the original OEM filter without modifications. The product is available in multiple languages and regional variants, yet the core specifications remain identical worldwide.

Installation Procedure

1. Locate the Cabin Air Filter Compartment: Typically found behind the glove box or under the dashboard on the passenger side.
2. Remove the Old Filter: Slide out the existing filter, noting its orientation for correct placement of the new unit.
3. Insert the CU 2424: Align the filter with the mounting edges and slide it into place until it clicks or locks securely.
4. Reassemble the Compartment: Replace any covers or panels, ensuring a tight seal to prevent air leaks.

Maintenance & Longevity

The CU 2424 is rated for 12–18 months of use, depending on driving conditions and environmental exposure. In dusty or pollen‑heavy environments, earlier replacement may be advisable to maintain optimal airflow and filtration efficiency. Regular inspection during routine vehicle maintenance helps prevent premature filter saturation.

Key Benefits for Vehicle Owners

• Improved Cabin Air Quality: Reduces allergens and pollutants, benefiting occupants with respiratory sensitivities.
• Enhanced HVAC Efficiency: Low airflow resistance keeps heating, ventilation, and air‑conditioning systems operating smoothly.
• Odor Control: Activated carbon layer mitigates unpleasant smells, contributing to a fresher interior experience.
• Durability: High‑grade materials ensure long service life even under harsh driving conditions.
