Yes. The 2020 Subaru Forester includes a cabin air filter as part of its HVAC system.
Cabin air filters help keep the air inside the vehicle clean by filtering dust, pollen, and odors before air enters the cabin. This is standard on Forester models and can come in a charcoal-activated variant for odor control. This article explains what the filter does, where to find it in a 2020 Forester, how to replace it, and how often you should check or replace it.
What is a cabin air filter and why it matters
A cabin air filter sits in the HVAC intake path and helps remove dust, pollen, mold spores, and odors from the air that comes into the passenger cabin. For allergy sufferers or drivers in urban or rural environments with pollution or strong smells, a clean filter improves air quality and can maintain HVAC efficiency. Some versions include activated charcoal to further reduce odors and certain gases.
Cabin air filter in the 2020 Forester: confirmation
For the 2020 Forester, the cabin air filter is a standard feature on most trims and is designed to be replaceable by the owner. The filter is located in the HVAC intake housing behind the glove box, and the replacement process is straightforward with common tools or none at all for some trims. As with most Subarus, be sure to install a new filter with the correct orientation so the arrows point in the direction of airflow into the cabin.
Where it sits and how to replace it
The following steps describe how to locate and replace the cabin air filter on a 2020 Forester.
- Open the glove box and clear its contents.
- Relieve the glove box by gently separating the sides or releasing the stops so the box can drop down and expose the HVAC intake housing behind it.
- Remove the filter cover by pressing tabs or sliding the cover off the housing.
- Take out the old filter, inspect the housing for debris, and dispose of the old filter properly.
- Insert the new filter with the arrows pointing in the direction of airflow (toward the HVAC unit). Ensure it sits flush in the housing.
- Reattach the filter cover, close the glove box, and test the HVAC to confirm proper airflow.
Replacing the cabin air filter is a quick maintenance task that helps maintain airflow efficiency and air quality inside the cabin. The process typically takes about 5–10 minutes and requires only basic hand tools or none at all, depending on your trim level.
Maintenance tips and replacement intervals
Maintenance intervals for the cabin air filter can vary, but a common guideline is to replace it at least once a year or every 12,000–15,000 miles, whichever comes first. In dusty, high-pollen, or urban environments, you may want to inspect and replace the filter more frequently. Always consult the owner’s manual or a Subaru dealer for the exact interval and compatible filter type (standard or charcoal).
Factors that affect replacement frequency
Environmental conditions (dust, pollen, pollution), driving habits, and whether you use recirculation mode can impact filter life. If you notice reduced airflow, musty odors, or increased allergy symptoms, inspect the filter and replace it as needed.
Summary
The 2020 Subaru Forester does have a cabin air filter, typically located behind the glove box in the HVAC intake. Replacing it is a straightforward maintenance task that helps ensure clean interior air and efficient climate control. Regular checks and timely replacements, aligned with the owner’s manual, help maintain optimal HVAC performance.
