The Fiesta's cabin air filter is located under the front passenger seat on the left side, behind the glove compartment. You can access it by removing the glove compartment. Here are some details about the cabin air filter: 1. The replacement interval for a car's cabin air filter depends on usage conditions. 2. For typical urban family cars, it's recommended to replace it every six months or annually. The functions of the cabin air filter include: 1. Ensuring a tight seal with the housing to prevent unfiltered air from entering the cabin. 2. Filtering out solid impurities such as dust, pollen, and abrasive particles from the air. 3. Adsorbing moisture, soot, ozone, odors, carbon oxides, SO2, CO2 from the air, with strong and lasting moisture absorption capabilities. 4. Preventing windshield fogging to maintain clear visibility for safe driving; providing fresh air to the cabin to protect occupants from harmful gases; offering powerful antibacterial and deodorizing effects. 5. Maintaining clean cabin air to prevent bacterial growth and create a healthy environment; effectively separating solid impurities like dust, powder, and abrasive particles from the air; efficiently intercepting pollen to prevent allergic reactions that might affect driving safety.

Among some cars I've worked on, the Fiesta's cabin air filter is quite easy to locate—it's usually hidden behind the glove compartment in front of the passenger seat. You'll need to remove the glove box first, find those small clips or screws, unscrew them, and then you'll see a small rectangular cover. Push it open, and the filter is right inside. Regularly replacing this thing is crucial; otherwise, the cabin air gets filled with dust and pollen, making the AC smell unpleasant when turned on. I recommend checking it every six months or every 10,000 kilometers. There are tutorial videos online, and all you need is a simple tool like a screwdriver. Oh, and when installing a new filter, make sure it's not put in backward—otherwise, the airflow decreases and cooling efficiency gets affected.

After driving a Fiesta for several years, I remember the cabin air filter is located near the passenger footwell. Just remove the panel behind the glove compartment to access it. I've replaced it myself a few times - the process isn't complicated, involving just two clips and pulling out the old filter. Changing it makes a big difference in air quality inside the car, especially beneficial for allergy sufferers. Make it a habit to check every spring or fall - don't wait until you notice odors when using AC. The filters are inexpensive (around 10-20 RMB), and DIY replacement saves repair costs while teaching you new skills. For older model years, the location might differ slightly, so it's best to consult your owner's manual for reference.

The air conditioning filter of the Fiesta is usually located behind the glove box on the passenger side. You can access it by opening the glove box and removing the cover panel. I recommend that all car owners familiarize themselves with this location, as timely replacement of the filter can help filter out polluted air and protect respiratory health. It's a simple yet essential task to replace it every year or every 15,000 kilometers. Though small in size, its impact is significant—ensuring more efficient cooling when the AC is on and preventing that annoying musty smell. Before starting, make sure to turn off the engine for safety.
