[VanJulianna]

Here is the method for replacing the cabin air filter in a Focus: 1. Pinch the two yellow clips and twist them downward; when reinstalling, simply press them back into place. 2. Remove the cabin air filter cover and push it back into position during reinstallation, aligning it properly. Pull out the cabin air filter. 3. The installation angle of the cabin air filter is tricky, but there’s no need to worry too much about deformation when pulling it out or installing it. Once in place, the filter will naturally expand without affecting its performance. Below are the functions of the Focus cabin air filter: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, providing strong and long-lasting moisture absorption.
