The Ford Focus uses a filter to prevent dust and airborne contaminants from getting into the passenger compartment of the vehicle. The filter should be changed every 15,000 miles or once a year for best results. The filter will get dirty faster if the air conditioning is run on a constant basis. Always purchase the air filter from an automotive parts store to get the best filter for your car.

  1. 1

    Position the windshield wipers in the up position for better access to the filter compartment.

  2. 2

    Open the bonnet to access the filter housing. The filter housing is located on the passenger side between the windshield and the firewall.

  3. 3

    Pry off the plastic caps with a flathead screwdriver to expose the Phillips-head screws. Unscrew them using a Phillips-head screwdriver. Place the screws and the caps to the side for installation.

  4. 4

    Pull the moulded plastic cover up to expose the filter. Pull the filter out of the housing. Remember how the filter was positioned so the new filter can be inserted correctly.

  5. 5

    Insert the new filter. Position the moulded plastic cover back over the filter housing.

  6. 6

    Tighten the screws in to the housing with a Phillips-head screwdriver. Push the plastic caps over the screws to complete the task.

  7. 7

    Close the bonnet. Lower the windshield wipers.
