Engineered with advanced filtration technology, it captures dust, pollen, smoke, odors, and microorganisms, ensuring that every breath you take inside your vehicle is free from contaminants.

Key Features

• High‑Efficiency Particulate Capture: With a multi‑stage design, the filter traps fine particles down to 0.3 µm, including pollen, dust mites, and airborne bacteria, reducing allergy triggers and improving cabin comfort.
• Long‑Lasting Performance: The robust construction resists clogging for extended periods, extending the interval between replacements compared to standard filters.
• Easy Installation: Designed for quick, tool‑free installation in a wide range of Volkswagen, Audi, and Skoda models. The filter fits snugly into the existing housing without modifications.
• Eco‑Friendly Materials: Made from recyclable components, the A8509 aligns with sustainability goals while delivering uncompromised filtration quality.

Installation Guide

1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and disconnect the battery for safety if required by your model’s service instructions.
2. Access the Cabin Filter Housing: Remove the glove compartment or interior panels as needed to expose the filter cover. In many models, this involves unscrewing a few screws or releasing plastic clips.
3. Remove the Old Filter: Gently pull out the existing filter. Dispose of it responsibly; activated carbon filters should not be recycled with regular waste.
4. Insert the Bosch A8509: Align the filter’s airflow arrows with the vehicle’s airflow direction and slide it into place until it clicks or locks securely.
5. Reassemble Interior Panels: Replace any panels, screws, or clips removed during access. Ensure all components are seated correctly to avoid rattles.
6. Reconnect Battery (if disconnected): Restore the battery connection and verify that the vehicle’s systems function normally.

Maintenance Tips

• Inspect the filter every 12–18 months or after driving through heavily polluted environments.
• Avoid using compressed air to clean the filter; this can damage the activated carbon layer.
• Replace the filter when you notice a noticeable drop in cabin air quality, increased odors, or reduced airflow from vents.
