• Durable Construction: Made from high‑grade synthetic fibers that resist moisture and maintain airflow performance over extended periods.
• Easy Installation: Designed to fit the standard cabin air filter housing in most passenger cars, including popular models such as Renault Espace IV, Peugeot 406, and various Volkswagen vehicles.
• Long‑Lasting Life Span: Engineered for extended service intervals, reducing maintenance frequency while preserving optimal airflow.

Technical Specifications

Benefits for Vehicle Owners

• Improved Cabin Air Quality: By trapping pollen, dust and odours, the filter protects occupants from allergens and reduces respiratory irritation.
• Enhanced HVAC Efficiency: Maintains optimal airflow through the heating, ventilation and air‑conditioning system, preventing strain on the compressor and blower motor.
• Reduced Maintenance Costs: The filter’s longevity means fewer replacements, saving time and money over the vehicle’s lifetime.
• Environmental Impact: High filtration efficiency reduces particulate emissions from the cabin, contributing to a cleaner environment for passengers.

Installation Guide

1. Open the vehicle’s hood and locate the cabin air filter housing beneath the front passenger seat or in the engine bay, depending on the model.
2. Remove the old filter by sliding it out of its slot. Dispose of it responsibly.
3. Align the new CUK 3840 filter with the airflow arrows indicated on the housing and slide it into place until it clicks or locks securely.
4. Close any covers or panels that were removed during access.
5. Start the engine and check for proper operation of the HVAC system; ensure no unusual noises or reduced airflow occur.

Maintenance Tips

• Inspect the filter every 12,000–15,000 km or annually, whichever comes first. Replace sooner if you notice a significant drop in cabin air quality or HVAC performance.
• Avoid using compressed air to clean the filter; this can damage the charcoal layer and reduce effectiveness.
• Keep the vehicle’s interior free from excessive dust by regularly cleaning surfaces and using high‑quality seat covers.
