To replace the Focus air conditioning filter, follow these steps: 1. Wait for the car engine to cool down and move the front passenger seat backward; 2. Remove the fuse box cover under the front passenger seat; 3. Press the switches on both sides and take off the vertical outer cover; 4. Locate the old air conditioning filter, press the outlet wire, twist and pull it outward to remove the filter; 5. After taking out the old air filter, install the new one. The air conditioning filter, commonly known as the pollen filter, functions to purify the air entering the cabin from outside by filtering out impurities, tiny particles, pollen, bacteria, industrial exhaust, dust, and other contaminants in the air.

Replacing the air filter in a Focus is actually quite simple. I've been driving this car for many years and often do it myself. Open the glove compartment on the passenger side—there are clips designed inside. Gently squeeze both sides to let it drop, and you'll see the filter cover. Lift the cover to remove the old filter, paying attention to the arrow direction on it, which indicates the airflow direction (usually pointing toward the rear of the car). When installing the new filter, make sure the direction aligns correctly—don't put it in backward, as it will affect filtration efficiency. Finally, close the cover and reset the glove compartment, and you're done. The whole process takes no more than 10 minutes and basically requires no tools—not even a screwdriver. I recommend changing it every six months. Choosing a high-quality activated carbon filter can reduce odors inside the car, especially during the rainy season, as it helps prevent mold. It saves money and hassle while avoiding overcharging at repair shops. The key is to check whether the filter is fully secured to prevent air leaks due to looseness.

I was quite nervous the first time I changed the air filter for my Focus, but it turned out to be quite user-friendly. Just lift the carpet in the passenger footwell or open the glove box to locate the clip-on filter cover. Press the clip to open the cover and pull out the old filter. Note that the new filter has a small arrow indicator—make sure it aligns with the airflow direction, usually pointing toward the front of the car. Push it in all the way and close the cover. The whole process can be done barehanded in just 5 minutes. After replacement, the AC airflow becomes noticeably stronger and fresher. I recommend changing it regularly in spring and autumn, and be sure to select the correct filter model. DIY is fun and helps you pick up new skills. If the clip is stubborn, don’t force it—check a tutorial first for reference.
