[SophiaFitz]

The cabin air filter in older Mazda 3 models is installed on the passenger side. Here is information about cabin air filters: 1. A cabin air filter is a filter installed in the vehicle's air conditioning system that absorbs dust particles, reduces respiratory irritation, minimizes stimulation for allergy sufferers, and protects the air conditioning cooling system; 2. It ensures the filter fits tightly against the housing to prevent unfiltered air from entering the cabin. It separates solid impurities such as dust, pollen, and abrasive particles from the air; 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and long-lasting moisture absorption; 4. It prevents the car windows from fogging up, ensuring clear visibility for drivers and passengers and safer driving; 5. It provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety.
