The cabin air filter in older 3 models is located beneath the glove compartment on the passenger side, and requires removal of the fuse box for access. Below are the functions of the cabin air filter in older Mazda 3 models: 1. Ensures the filter fits snugly against the housing to prevent unfiltered air from entering the cabin. 2. Filters out solid impurities such as dust, pollen, and abrasive particles from the air. 3. Absorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and lasting moisture absorption capabilities. 4. 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 occupants from inhaling harmful gases and ensuring driving safety. It also effectively sterilizes and deodorizes the air.

Speaking of the cabin air filter location on the old 3, I remember it clearly from when I changed it myself last time. First, you need to open the glove compartment in front of the passenger seat, then remove the clips on both sides of the glove box. With a gentle pull, the entire glove box can be detached. Behind it, you'll see a black plastic cover secured by about two or three plastic clips. Remove this cover to reveal the filter slot. This design is actually quite hidden - it took me a long time to find it the first time. I recommend doing this in daylight when there's plenty of light, otherwise those small clips can be hard to see. Remember to empty any items from the glove box first, as this will make the operation much smoother. The whole process takes about ten minutes to complete.

I've been driving my old 3 for about seven or eight years, and the cabin air filter is located behind the glove compartment on the passenger side. The process is quite simple: first, empty the glove compartment, then on the inner walls of the glove compartment, there are plastic stoppers on both the left and right sides. Press them inward with your hands to allow the glove compartment to hang down. At this point, look down at the back of the glove compartment, and you'll see a rectangular plastic cover with clips. Use a flathead screwdriver to pry open the cover, and you'll find the filter inside. When removing the filter, pay attention to the airflow direction arrow to avoid installing it backwards. A new filter purchased online is quite cheap, costing only about 30 to 50 yuan. Regular replacement is especially important for people with rhinitis, so I replace it myself every year when the seasons change.

I previously helped a neighbor deal with the musty smell in their old 3's air conditioning system, and found the key was the cabin air filter location. It's behind the glove compartment on the passenger side - you need to remove the entire glove box to access the filter housing. Removing the glove box isn't difficult: first lift the bottom firmly upwards to release the stops, then pull outward to remove it completely. The exposed black plastic cover has obvious clip markings - just pry it open to replace the filter. This design isn't exactly ideal - at repair shops, the labor cost for replacement often exceeds the price of the filter itself.

The AC filter replacement location on the old 3 is really frustrating. Last time it took me forever to find it. You have to remove the glove compartment on the passenger side to access it. First, detach the damper rods on both sides of the glove box, then deal with the retaining clips at the bottom. Once fully removed, you'll see the filter compartment cover - a palm-sized plastic panel. It's recommended to buy OEM-sized filters, as thicker ones won't fit. Wear gloves when DIY replacing, as the plastic edges have sharp burrs. After replacement, run the blower at maximum speed for a few minutes to clear any paper debris from the new filter.

The cabin air filter in the old 3 is hidden behind the glove compartment on the passenger side, with a rather ergonomically-challenged design. You'll need to kneel on the passenger floor to access it. First, empty all items from the glove box, then locate the stopper clips on both sides of the compartment. Rotate these clips 90 degrees to release the glove box. After removing the compartment, you'll see a rectangular black filter cover panel - its clips can be easily pried open with your fingernails. Important reminder: Avoid forcefully pulling the soft rubber edges of the filter frame as they tend to crack when aged. For DIY replacement, we recommend purchasing an activated carbon composite filter for better odor elimination.
