I've been driving a 2010 Mazda3 for five years and changed the cabin air filter three times. It's hidden behind the glove box on the passenger side, so you need to remove the glove box first. There are plastic clips on both sides - press them firmly inward to detach the glove box. After removal, you'll see a rectangular cover panel, usually made of black plastic with arrow markings. Use a screwdriver to pry open the clips and remove the old filter. Remember the filter has directional markings - don't install the new one backwards. The filter location is reasonably designed in this car, though the first replacement might take about 30 minutes to figure out. By the way, it's better to choose an activated carbon filter as it blocks an extra layer of dust compared to standard filters.

Last week, I just helped my neighbor replace the cabin air filter for a 2010 3. You'll need a T20 Torx screwdriver and a new filter. Sit in the passenger seat and open the glove box. You'll see a stopper on each side of the glove box compartment. Press the protruding parts of both stoppers simultaneously, and the entire glove box will drop down. Behind it, you'll see the vertical filter cover. Press the clips on both sides to open the cover. Be careful not to spill dust when removing the old filter. Install the new filter with the 'UP' mark facing upward. Doing it yourself can save you about 200 yuan in labor costs, but the working space is a bit tight, which might be challenging for those with larger hands.

The cabin air filter for the 2010 Mazda3 is located inside the glove compartment on the passenger side. The removal steps are quite simple: 1. Empty the glove compartment 2.

It's recommended to replace the filter every 15,000 km or before the rainy season, especially in humid southern regions.

I remember the first time I replaced the air filter for my old 3 was at the dealership. Later, I discovered it's located right in front of the passenger seat. No tools are needed to remove the glove box—just squeeze both sides inward with your hands and pull downward. The rectangular filter housing cover has small arrows indicating the opening direction. This design is much more user-friendly compared to some models that require dismantling the dashboard. When replacing, pay attention to comparing the sizes of the old and new filters, as some owners have purchased mismatched sizes. Spring and autumn are the best seasons for replacement, and it's a good opportunity to clean out leaves and debris from the air ducts.

You'll see a plastic cover labeled 'pollen filter' - squeeze the clips on both ends to open it. The filter is an accordion-fold style; when installing, ensure the airflow direction arrow faces upward. This location design is cleaner than engine bay filter replacements, avoiding dirty clothes. However, be careful not to tug on the wiring harness behind the glove box. For first-time replacement, choose a weekend afternoon and allow a full 30 minutes for exploration.
