Replacing Cabin Air Filter

Model: Ford Focus MK 1 - Years 1998-2004
Part: Cabin air filter

The cabin air filter is located in the engine compartment, just below the windscreen, on the right side when facing forward. Remove the plastic protective grille by extracting the clips and take out the old filter, clearing any dirt residue, and insert the new filter, ensuring the airflow direction is correct. When replacing the cabin air filter, it is also advisable to sanitise the air conditioning system using a specific germicidal spray, which will not only provide a pleasant scent in the cabin but will also eliminate any mould present in the ventilation ducts.
