I've been driving my Mazda 3 for five years now, and the cabin air filter is located behind the glove compartment in front of the passenger seat. After opening the glove box, you'll find clips at the bottom—just push them upward to remove it, revealing a rectangular slot where the filter sits. After replacing it, the air inside the car becomes much fresher, filtering out dust and pollen, making driving more pleasant. It's recommended to replace it every year or every 15,000 kilometers. The filter costs just a few dozen yuan online—simple and cheap. If you don't replace it, the AC may blow out unpleasant odors, affecting health and increasing fuel consumption. It takes only 20 minutes to do it yourself—just prepare a new filter and a screwdriver. When inserting the filter, pay attention to the arrow direction to avoid installing it backward. Remember this location to avoid unnecessary expenses during maintenance.

I find the cabin air filter on the Mazda 3 quite easy to locate - it's right under the glovebox on the passenger side. Just pull the glovebox door all the way down, look for the small latch on the side, and once you release it, you'll see the filter compartment. DIY replacement is super convenient, no need to visit a shop. Changing it annually keeps the air cleaner. When selecting a filter, go for one with PM2.5 protection for better performance. Also, don't forget to check the direction - the arrow should point in the direction of airflow. If left unchanged for too long, it can get clogged, causing slower cooling and unpleasant odors. I save hundreds each time by doing it myself, using just a screwdriver from home. Even beginners can try it - there are plenty of online tutorials available.

I'm an average driver, using a Mazda 3 for daily commuting. The cabin air filter is hidden behind the glove box, and replacing it isn't difficult—just open the compartment and remove the clips to access it. Regularly changing it is important as it filters out dust and bacteria, making breathing easier. Generally, once a year is sufficient.
