Here is the tutorial for replacing a car's cabin air filter: 1. Locate the filter area following the arrow indicator direction; 2. Unscrew the two fixing screws on the foam cover by hand; 3. Remove the foam cover to expose the cabin air filter cover; 4. Push rightward to remove the cabin air filter cover; 5. Take out the old filter and replace it with a new one; 6. Install with the black side facing the rear of the vehicle and the arrow pointing toward the front; 7. Insert the cabin air filter, reinstall the filter cover, and complete the process. The functions of a car's cabin air filter are as follows: 1. Ensures the filter fits tightly against the housing to prevent unfiltered air from entering the cabin. 2. Separates solid impurities such as dust, pollen, and grinding particles from the air. 3. Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and long-lasting moisture adsorption capabilities.

Last time I replaced the cabin air filter myself, and it was actually quite simple. Open the glove compartment of your vehicle – in many models, the filter is located right behind it, so remember to empty the compartment first. Then, press the clips on both sides or unscrew any fasteners to remove the compartment, but avoid using excessive force to prevent damage. Next, you'll see a rectangular filter cover. Open it and gently pull out the old filter, paying attention to the directional indicator – the arrow points in the direction of airflow, so don’t install it backward. Insert the new filter, secure the cover and glove compartment, and the whole process takes about ten minutes. Don’t forget to replace it once a year, especially if you drive frequently in the city where dust buildup can block the filter and reduce AC airflow, which also harms air quality and respiratory health. Doing it yourself can save you a hundred bucks in service fees, and it’s easy enough for beginners to learn. Keeping a spare filter in the car is always a good idea.

As a mom who drives kids daily, I find changing the cabin air filter super practical. Locate the filter—most are behind the glovebox. Empty it, gently press the clips to remove the compartment, and you'll see the cover. Open it, remove the old filter (note arrow direction when inserting the new one). Take your time to avoid hand injuries. After installation, check if airflow improves. Typically replaced every 1-2 years at low cost. Regular changes prevent odors/bacteria, maintaining fresh cabin air—especially crucial for kids' health. Far more convenient and budget-friendly than professional shops.

I'm an experienced driver with plenty of filter replacement skills. Just open the glove box, remove the old filter, and install the new one following the airflow direction. The location may vary by vehicle model, but it's generally simple. The AC performance will improve immediately after replacement. Pay attention to the replacement cycle.
