The 2020 Subaru Forester has two air filters: one engine air filter and one cabin air filter.
What types of air filters are included
The 2020 Forester employs two distinct filtration systems to protect both the engine and the occupants. Below is a breakdown of each filter and its role in the vehicle’s performance and comfort.
- Engine air filter: cleans the air entering the engine’s intake so combustion remains efficient and consistent.
- Cabin air filter: cleans the air entering the vehicle interior through the HVAC system to improve cabin air quality.
Both filtration systems are designed to be replaced at intervals recommended by Subaru’s maintenance schedule or the owner’s manual, with replacements typically tied to mileage for the engine filter and annual or mileage-based recommendations for the cabin filter depending on driving conditions.
Engine air filter
The engine air filter sits in a housing in the engine bay, usually accessed by removing the housing cover or clips. Replacement is commonly performed around every 30,000 miles under normal driving conditions, but owners should consult the manual or a dealership for guidance specific to their environment.
Cabin air filter
The cabin air filter is located behind the glove box. Access typically requires lowering or removing the glove box panel to reach the filter element. Replacement intervals commonly align with annual service or every 15,000–30,000 miles, depending on factors such as climate and road conditions.
Summary
In summary, the 2020 Subaru Forester uses two air filters—an engine air filter and a cabin air filter—providing targeted protection for both the powertrain and the interior air quality. Regular inspection and replacement per Subaru’s guidelines help maintain performance and comfort.
