FAQ

This filter is designed for select Mazda vehicles, including the Mazda 3, Mazda 6, and CX-5. It serves as a direct replacement for OEM part numbers KD45-61-J6X and KR11-61-J6X.
The CF11811 cross-references with several industry standard part numbers, including CPJ6X, CAF1907P, CAF1907C, CU24009, and MP11-1K-D45.
You should consider replacing your cabin air filter if you notice reduced airflow from your HVAC vents, persistent unpleasant odors inside the cabin, or increased dust accumulation on your dashboard. Generally, it is recommended to replace the filter every 12,000 to 15,000 miles, or more frequently if you drive in dusty or heavily polluted environments.
Installation is a straightforward DIY task that typically takes less than 10 minutes. In most compatible Mazda models, the cabin air filter is located behind the glove box. You will generally need to lower the glove box assembly to access the filter housing; no specialized tools are required for this process.
Unlike standard paper filters that only trap dust and pollen, the activated carbon layer in this filter helps neutralize odors and absorb harmful gases and pollutants before they enter the vehicle cabin, providing a fresher interior air quality.
