How to Replace the Air Conditioning Filter in a Mazda 3?

The method for replacing the air conditioning filter in a Mazda 3 is as follows: 1. The air conditioning filter is located inside the glove compartment on the passenger side. First, remove the lower dashboard panel on the passenger side, which is usually secured by plastic clips. Once removed, you will see a rectangular fuse box. After removing the fuse box, the location of the air conditioning filter will be visible. Take off the filter cover, pull out the old filter by hand in the direction indicated by the arrow, install the new filter, and then reassemble everything. 2. The Mazda 3 is a vehicle under Changan Mazda, with body dimensions of 4515mm in length, 1745mm in width, and 1465mm in height, and a wheelbase of 2640mm. In terms of exterior design, the Mazda 3 features a low-sloping chrome five-point grille, with three sharp lines extending towards the hood. The modern and avant-garde first impression is enhanced by the three-tube eagle-eye headlights with a dark finish.

Last time I changed the air filter for my Mazda3 by myself, it was quite simple. The filter is located behind the glove compartment on the passenger side. Just prepare a T20 screwdriver, and you can remove the glove compartment by pulling the damper rod away. Unscrew the two screws on the inner cover, and you'll see the filter slot. When pulling out the old filter, pay attention to the arrow direction, and insert the new filter back in the same orientation. I took the opportunity to clean out the leaves and debris in the slot. After installation, the airflow from the AC noticeably improved. Doing it myself saved over 200 yuan compared to the dealership. I bought a Mann filter online for just a few dozen yuan—remember to get one with activated carbon for better performance. Spring, when pollen is abundant, is the best time to replace it.

If you notice any odor from the AC, it's time to replace the filter. I change mine every 10,000 kilometers or so. In the Mazda3, the filter is located behind the glove box, and it's most convenient to access by opening the passenger door. To remove the glove box, first press the clips on both sides to release the hinges—don't yank it hard. The screws on the filter compartment cover can be handled with a Phillips screwdriver. When I replaced mine, the filter was completely clogged with poplar and willow catkins. Make sure to align the arrow on the filter with the airflow direction to avoid installing it backward. After installation, run the AC on high for a few minutes to dissipate any new filter smell. For those less handy, check the owner's forum for illustrated guides—it should take about half an hour to complete.

The cabin air filter is located behind the glove box, and it's safer to operate when the engine is off. Open the passenger side storage compartment and release the glove box by pushing aside the buffer rods on both sides. Remove the three screws on the filter cover plate to take out the old filter, paying attention to the installation direction marked on the side of the filter with the arrow pointing downward. It is recommended to use the original equipment manufacturer (OEM) filter for the best fit. When reinstalling the screws, avoid overtightening them. I always take the opportunity to check the blower for any debris. Regular replacement can improve cooling efficiency by more than 20%, especially in humid southern regions where more frequent changes are necessary.
