Original MANN-FILTER Interior Filter CU 2542-2 – Cabin air filter set

Product Overview

The MANN‑FILTER Interior Filter CU 2542-2 is a premium cabin air filter designed for passenger cars. It comes as a set of two filters, ensuring that both the front and rear sections of the vehicle’s HVAC system receive optimal protection against airborne contaminants.

Key Features

• Dual‑Stage Filtration: Combines high‑efficiency particulate capture with advanced pollen and odor removal technology.
• High Flow Rate: Maintains airflow comparable to a new filter, preventing pressure loss in the HVAC system.
• Durable Construction: Made from reinforced paper media and a protective outer shell that resists moisture and dust buildup.
• Easy Installation: Snap‑in design fits standard MANN‑FILTER mounting brackets without the need for tools.
• Long Service Life: Designed to last up to 15,000 km (or 12 months) under normal driving conditions before requiring replacement.

Design and Construction

The CU 2542-2 features a layered media architecture. The outer layer is engineered for rapid dust capture, while the inner layers employ electrostatic attraction to trap fine particles such as pollen, mold spores, and airborne pollutants. This multi‑layer approach ensures that the cabin remains free of irritants, contributing to a healthier driving environment.

Material Composition

The filter media is composed of high‑grade cellulose fibers bonded with a non‑ionic polymer matrix. The outer shell is constructed from a lightweight yet robust polypropylene casing that protects the media during handling and installation.

Performance Characteristics

• Particle Removal Efficiency: 99.5% for particles ≥0.3 µm, ensuring near‑complete elimination of fine dust and allergens.
• Airflow Resistance: < 10 Pa at a flow rate of 300 L/min, which is within the optimal range for most passenger car HVAC systems.
• Temperature Range: Operates effectively from –40 °C to +80 °C, suitable for both cold and hot climates.

Installation Guide

1. Locate the cabin air filter housing behind the glove compartment or under the dashboard, depending on vehicle model.
2. Open the housing cover and remove any existing filter. Dispose of it responsibly.
3. Align the new CU 2542-2 filter with the mounting tabs and slide it into place until it clicks securely.
4. Close the housing cover and ensure a tight seal to prevent unfiltered air from entering the cabin.

Compatibility Checklist

The CU 2542-2 is engineered for a wide range of passenger cars, including models from Hyundai, Ford, Volkswagen, and many others. Always verify the part number against your vehicle’s service manual before installation.

Maintenance Tips

• Inspect the filter every 6 months or after significant exposure to dusty environments.
• If you notice a decrease in HVAC performance or an odor inside the cabin, replace the filter immediately.
• Avoid using compressed air on the filter as it can damage the media layers.

Benefits for Vehicle Owners

• Improved Cabin Air Quality: Reduces allergens and pollutants, enhancing driver and passenger comfort.
• Enhanced HVAC Efficiency: Maintains optimal airflow, preventing strain on the heating and cooling system.
• Reduced Wear on Interior Surfaces: Keeps dust from settling on seats and dashboards, preserving interior aesthetics.
• Healthier Driving Experience: Lowers exposure to airborne irritants, beneficial for individuals with respiratory sensitivities.
