Puroma Cabin Air Filter Activated Carbon for CF11811 CPJ6X Mazda 3&6 CX-5
  • Enhanced Air Quality: Soda woven combined with activated carbon effectively captures contaminants that cause odors and ensures that the air inside the vehicle is fresh and clean. The activated carbon layer provides slight sound absorption, reducing noise levels for a quieter cabin environment. It can also reduce the likelihood of window fogging and improve visibility.
  • Efficient Filtration: The close-meshed non-woven filter layer prevents particles from entering the cabin, protecting your engine from wear and extending the life of your vehicle's system. By filtering out harmful pollutants such as smog, smoke, and microscopic contaminants, it safeguards passengers' health and comfort and offers clean and fresh breeze air.
  • Enhances HVAC performance: It is recommended to replace your cabin air filter every year or every 12,000 miles. For optimal performance, those driving in heavily polluted areas or on dirt roads should change it every 5,000 miles. These filters help maintain the efficiency and longevity of the vehicle's heating, ventilation, and air conditioning (HVAC) system, maintaining optimal airflow and reducing strain on the system.
