Performance Benefits

The FP 3540 delivers a multi‑layer filtration experience that protects occupants from:

• Allergens: Pollen, mold spores and pet dander are effectively trapped by the biofunctional layer.
• Fine Particulate Matter: PM 2.5 particles are captured with high efficiency, improving respiratory comfort.
• Odours and Gases: Activated carbon adsorbs unpleasant smells and harmful gases, maintaining a pleasant cabin environment.
• Microbial Growth: Antibacterial properties reduce the risk of bacterial proliferation within the filter media.
• Engine Load: Low pressure drop ensures minimal impact on HVAC system performance.

Installation Guide

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

1. Locate the cabin air filter housing beneath the dashboard, typically below the plenum chamber cover.
2. Remove the housing cover by unscrewing or unclipping, depending on the vehicle model.
3. Slide out the old filter carefully to avoid contaminating the interior air.
4. Insert the new FP 3540 filter, ensuring that the airflow arrow points in the correct direction.
5. Reattach the housing cover securely, tightening screws or re‑engaging clips.
6. Verify that the HVAC system is functioning normally and that no unusual noises are present.

Maintenance Tips

• Check the filter every 12,000 km or annually, whichever comes first.
• Inspect for visible dust accumulation; a heavily loaded filter may indicate the need for earlier replacement.
• Avoid using compressed air to clean the filter; this can damage the biofunctional layers.
• Store unused filters in a dry, cool environment to preserve their integrity.
