Where is the cabin air filter located in a Mazda3?

[LeAnnie]

The cabin air filter in a Mazda3 is located beneath the glove compartment on the passenger side. To access it, you'll need to remove the fuse box - the filter position is to the left of the fuse box, where you'll find two filters. The replacement difficulty level is about 80%. We recommend having it replaced by professional technicians at a repair shop. The primary function of the cabin air filter is to filter out dust, mist, pollen, carbon oxides, sulfur compounds, etc. from the air to ensure the cleanliness and proper operation of the vehicle's air conditioning system. Another important role is to maintain good air quality inside the cabin. The Mazda3 uses a dual-piece cabin air filter design. When driving with the air conditioning on, outside air enters the cabin carrying various particles including dust, pollen, soot, abrasive particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. These particles can not only contaminate the air conditioning system but also reduce the cooling system's efficiency, making regular replacement necessary. The replacement interval for a car's cabin air filter depends on usage conditions. For typical urban family cars, it's recommended to replace it every six months to one year. Additionally, seasonal variations in air conditioning usage frequency may also affect the replacement schedule.
