A few days ago, I replaced the cabin air filter in my 3, and the process was quite straightforward with just a few steps. First, locate a securing clip under the glove compartment and gently pull it off to remove the entire glove box. Behind it, you'll find a small cover—either unscrew or pry it open to access the old filter. Pay close attention to the airflow direction arrow on the filter to avoid installing it backward. Then, align the new filter with the arrow, insert it, close the cover, push the glove box back into place, and secure the clip. The whole job takes about 10 minutes. It's recommended to replace the filter annually, especially before spring and autumn seasons, to prevent musty air inside the car and ensure more comfortable breathing while driving. Be gentle during the process to avoid damaging plastic components—even beginners can handle this task easily.

3 owner shares a little tip: The key to replacing the cabin air filter lies in glove box removal. First, sit in the passenger seat, clear any items from the footwell, then locate two clips at the bottom. Gently pry them outward with your fingers to detach the entire glove box. Next, open the filter compartment cover and slowly pull out the old filter, remembering to note the arrow direction. Insert the new filter in the same orientation, ensuring it fits snugly without looseness. After installation, push the glove box back into place until it clicks. I typically replace it every 12,000 km or once a year to maintain fresh airflow and prevent bacterial buildup. It's a simple, low-cost DIY procedure that saves both hassle and money.
