Driving on dusty roads makes the filter dirty much more quickly.
Some models of the Ford F-150 are equipped with a cabin air filter that prevents dust and pollen from entering the cab of the truck. Ford recommends replacing the filter at least once per year or after every 10,000 miles. If the F-150 is often driven in dusty conditions, the filter should be inspected and replaced more frequently. A clean cabin air filter improves air flow in the air conditioning system.
1. Open the glove compartment and remove its contents.
2. Remove the two screws on the inside top of the glove compartment to unhook it from the dash.
3. Pivot the glove box down toward the floor of the F-150 to expose the cabin filter housing.
4. Press in on the clips on both sides of the cabin filter housing to unhook it. Pull the filter housing cover off.
5. Pull the old filter straight out of the filter compartment to remove it.
6. Slide the new filter into the filter compartment. Make sure the arrow printed on the filter is pointing toward the roof of the F-150.
7. Replace the filter housing cover. Press on the sides of the cover until it snaps into place.
8. Lift the glove compartment up and reposition it to the original position. Replace the two screws that secure the glove compartment to the dash.
