Yes. The 2017 Subaru Outback is equipped with a cabin air filter (often called a pollen filter).
It sits behind the glove box and helps filter dust, pollen and pollutants from the cabin air. Replacing it on a regular schedule improves HVAC performance and interior air quality. In dusty conditions or heavy traffic, more frequent changes may be needed. The guide below explains where to find the filter, how to replace it, and maintenance tips.
Where to find the cabin filter
The cabin air filter on most 2017 Outback models is located behind the glove box on the passenger side. Access is gained by opening the glove box, releasing its stops, and lowering the box to reveal a rectangular filter housing. If your trim has a different dash configuration, consult the owner’s manual for the exact location.
Access and replacement steps
Use the following steps to access and replace the cabin filter:
- Open the glove box and squeeze the sides to release the stoppers, allowing the box to drop down.
- Locate the rectangular filter housing behind the opened glove box and remove its cover by unclipping the tabs.
- Remove the old cabin air filter, taking note of the orientation.
- Insert the new filter with the airflow arrows pointing toward the rear of the vehicle, ensuring it sits flat in the housing.
- Reattach the housing cover, lift the glove box back into place, and redeploy the glove box stops.
After replacement, run the HVAC on fresh air for several minutes to clear any residual dust, then reset any maintenance reminders if your vehicle uses them.
Maintenance and replacement interval
For normal driving, Subaru generally recommends replacing the cabin air filter every 12,000–15,000 miles or about once a year. In dusty or urban environments, check sooner and replace more frequently. Signs that the filter needs attention include a musty odor, reduced airflow, or increased cabin dust.
Summary
The 2017 Subaru Outback does have a cabin air filter located behind the glove box on the passenger side. Replacing it on a regular maintenance schedule improves air quality and HVAC performance. The replacement process is straightforward and can be done with basic tools, following the steps outlined above. Always verify part compatibility with your exact trim and consult the owner’s manual or a Subaru dealer if you’re unsure.
