Method for replacing the Focus air conditioning filter: 1. Pinch the two yellow clips and twist them downward; when reinstalling, simply press them back into place. 2. Remove the air conditioning filter cover; when reinstalling, align it and push it back into position. 3. Pull out the old air conditioning filter. The installation angle of the filter is quite tricky, but there's no need to worry too much about the filter deforming during removal or installation—it will naturally expand into place without affecting performance. Functions of the air conditioning filter: 1. Ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. Separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and lasting moisture absorption. 4. Prevents car windows from fogging up, ensuring clear visibility and safe driving; provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; effectively sterilizes and deodorizes. 5. Maintains clean cabin air, preventing bacterial growth and creating a healthy environment; effectively separates solid impurities such as dust, filter powder, and abrasive particles from the air; effectively blocks pollen, ensuring occupants do not experience allergic reactions that could compromise driving safety.

Changing the Focus air filter is actually super easy. I've done it several times myself, and the whole process takes less than ten minutes. The filter is located behind the glove box. First, empty the glove box, then push the clips on both sides of the box with both hands, and gently press to remove the glove box. Inside, you'll see a rectangular plastic cover—just pry it open to pull out the old filter. Make sure to buy the correct model for the new filter, and when installing it, the arrow on the filter must point toward the interior or the airflow direction. Don't install it backward, or the filtration will be poor. After installation, reassemble all the parts in order. Regularly replacing the filter can significantly improve cabin air quality, especially in summer when the AC is used frequently. It prevents musty odors and protects respiratory health—don't wait until the AC starts smelling bad to take action. This DIY saves money and enhances the driving experience.

Open the glove box, empty its contents, then press down firmly on both sides to release the clips and remove the box. Inside, there's a hidden filter cover—pry it open to easily remove the old filter. When installing the new filter, pay attention to the directional arrow, aligning it with the airflow indicator to avoid incorrect placement that could reduce effectiveness. Once done, reattach the glove box by reversing the steps and securing it tightly. It's recommended to check and replace the filter every six months or 10,000 kilometers to prevent dust and bacteria buildup, which can affect health. Numerous online tutorials are available, making it a safe task even for beginners.
