Subaru Cabin Air Filter - 2018-2021 Subaru WRX / STI / 2018 Forester

What Do Cabin Air Filters Do?

Cabin air filters play a crucial role in maintaining air quality inside your vehicle by trapping foreign particles from outside air that enter through your HVAC (Heating, Ventilation, and Air Conditioning) system. These particles include dust particles, allergens, pollutants, mold spores, bacteria, and debris.

 

When Should Cabin Air Filters Be Replaced?

It's recommended to replace your cabin air filter approximately every 12,000 miles or if you notice decreased airflow of hot or cold air, unpleasant odors coming from the vents, or if you've exceeded the service interval mileage. A clean cabin air filter not only ensures the air you and your passengers breathe is of high quality but also optimizes airflow when using the heat, defrosters, or air conditioning.

 

Why Choose Genuine Subaru Cabin Air Filters?

Using Genuine Subaru Cabin Air Filters offers several advantages:

• Exact fit into your HVAC system, ensuring proper installation and performance.
• Engineered materials effectively trap microscopic particles, maintaining air quality.
• Ensures maximum airflow, optimizing the performance of your HVAC system.
• Generic cabin air filters may compromise heating and air conditioning performance.

 

Note: The recommended replacement interval of 12,000 miles is based on Maintenance Schedule intervals found in your Warranty & Maintenance Booklet. However, your specific interval may vary depending on your Subaru vehicle model. Additionally, environmental factors such as road conditions and weather, as well as individual driving habits, may necessitate more frequent replacements.
