Description
Carbon filter, activated carbon for Citroën C4 and Peugeot 307
This activated carbon cabin filter is intended for the ventilation system of Citroën C4 and Peugeot 307 vehicles. Designed to reduce odors, trap fine dust, pollen and soot particles, it improves in-cabin air quality and helps maintain HVAC performance. The part is commonly searched under the code 1502F9, making it easy for technicians and DIY enthusiasts to find the correct replacement.
By using an active carbon media, the filter not only captures particulates but also adsorbs volatile organic compounds (VOCs) and unpleasant smells from road and exhaust fumes, which is especially beneficial in urban environments or after prolonged use. Installation is straightforward for experienced mechanics and competent home mechanics, and regular replacement restores airflow, reduces HVAC strain and improves demisting performance.

Why The Part Typically Fails
Cabin filters become ineffective primarily due to clogging with road dust, pollen, brake and tire particles and soot. Clogged media reduces airflow, causes weaker heating and cooling performance, increases cabin odours and can contribute to rapid fogging of the windshield. In humid or polluted environments, moisture retention can also promote microbial growth and unpleasant smells. Physical damage or improper installation can also compromise filtration efficiency.
Installation Recommendations
Location: The cabin filter is located in the HVAC intake area (commonly behind the glovebox or under the cowl on the passenger side on these models). Access method can vary slightly by model year.
- Park Vehicle Safely And Cut Electrical Loads.
- Remove Glovebox Or Cowl Cover To Expose Filter Housing (Use Trim Tool Or Screwdriver As Required).
- Unclip Or Unscrew The Filter Cover And Carefully Slide Out The Old Filter.
- Inspect And Clean The Filter Housing And Drain Channels From Leaves Or Debris.
- Insert New Filter With Correct Airflow Orientation (Follow Arrow Marking On Filter).
- Reassemble Components And Perform A Quick HVAC Function Check For Airflow And Odour.
Tools Typically Required: Basic Screwdrivers, Trim Removal Tool, Shop Cloth. Take Care Not To Damage Seals, Clips Or The Blower Unit. Replace The Filter With The Airflow Arrow Pointing Toward The Cabin.
Service Interval
Recommended Replacement Interval: Typically Every 15,000–30,000 Km Or Every 12–24 Months, Depending On Driving Conditions. In Heavily Polluted Or Dusty Areas, Replace More Frequently.
