Where is the cabin air filter located in the Changan Mazda 3?

The cabin air filter in the Changan Mazda 3 is located behind the glove box, which needs to be removed for access. Under normal circumstances, the replacement frequency of a car's cabin air filter depends on usage conditions. For typical urban family vehicles, it's recommended to replace it every six months or annually. Below is relevant information about the cabin air filter: 1. When driving with the air conditioning on, the vehicle draws in outside air into the cabin. However, this air contains various particles such as dust, pollen, soot, abrasive particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. 2. Without the cabin air filter's filtration, these particles entering the cabin would not only contaminate the air conditioning system and reduce cooling performance, but also cause allergic reactions when inhaled by passengers, potentially damaging lungs, creating irritability from ozone exposure, and affecting driving safety due to odors.
As an owner of an older Mazda3, I can tell you definitively that the cabin air filter is located behind the glove compartment on the passenger side. To remove it, you need to fully open the glove box and squeeze it inward to detach it, then you'll see a rectangular cover plate. I didn't know this before either, but a friend showed me how simple it actually is. Don't use the filter for too long—in humid southern climates, it's best to replace it every six months, otherwise the AC will start emitting a musty smell. When replacing, pay attention to the arrow direction on the filter to avoid installing it backward. You can buy a Mann or Mahle filter for around 30 yuan yourself, saving over 100 yuan compared to dealership prices, and the whole job takes just ten minutes.
Just last week, I replaced the cabin air filter for my Mazda3 (Axela), located right by the passenger-side knee area. Adjust the seat backward to create space, then crouch down and look up at the bottom of the glove compartment to spot a clip-on cover. Gently pry open the cover with a screwdriver to pull out the filter. Remember to use your phone's flashlight for better visibility—poor lighting can lead to mistakes. Opt for an activated carbon filter if possible; though pricier, it's more effective against PM2.5.
