The cabin air filter of the Mazda 3 is installed in the passenger compartment. You need to remove the fuse box and look to the left to see the cover plate of the cabin air filter. The following are the functions of the filter: 1. It ensures that the air filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and long-lasting moisture adsorption. 4. It prevents the car windows from fogging up, ensuring clear visibility for the driver and passengers, thus enhancing driving safety. It provides fresh air to the cabin, preventing the inhalation of harmful gases and ensuring driving safety. It also has strong antibacterial and deodorizing properties. 5. It maintains clean air in the cabin, preventing bacterial growth and creating a healthy environment. It effectively separates solid impurities such as dust, core powder, and abrasive particles from the air and efficiently intercepts pollen, ensuring that the driver and passengers do not experience allergic reactions that could affect driving safety.

As someone who frequently drives a Mazda 3, I can tell you that the cabin air filter is located inside the glove compartment on the passenger side. You'll need to open the glove box door first, empty out any items inside, then check the bottom or rear wall where there's usually a plastic cover or clip. Gently press or pry it open with your hand to reveal the filter slot. This thing filters the air inside the car, blocking dust and pollen to ensure smooth breathing while driving. It's recommended to replace it every 15,000 kilometers or once a year. DIY replacement is quite simple: first measure the size of the old filter, buy the same model online, and when installing, pay attention to the direction arrow - don't put it in backwards, the arrow should point in the direction of airflow. It saves money and teaches you some skills, no need to always go to the dealership and waste money - one service fee could buy several filters.

When I first drove the Mazda 3, I was also curious about where the cabin air filter was located. Later, I found it in the glove box area. Open the glove box door on the passenger side, and you'll see it empty inside. There's a small panel at the back or bottom that you can push or unscrew a small screw to remove. The filter is embedded inside there. The cabin air filter can trap dust and odors, and not replacing it for a long time can affect your health. I usually check it every 10,000 kilometers. Replacing it yourself is quite easy—just buy a new filter (choose the Mazda 3-specific model online) and make sure not to install it backward when replacing the old one; the arrow should point toward the interior of the car. Doing it yourself saves time and money, and the air in the car becomes much fresher.

The cabin air filter location is simple: behind the glove box. Open the glove box door, remove it or the cover, and the filter will be exposed. Replace it regularly to prevent dust allergies, every two years is sufficient. It's easy to replace it yourself, and a new filter costs just a few dollars online.
