The cabin air filter in a 2016 Prius is located behind the glove box on the passenger side of the dashboard, accessed by lowering the glove box and removing a small cover on the filter housing.
In the 2016 Prius (Gen 4), the filter sits in a housing behind the glove box. Replacing it is a straightforward task that typically takes 10–15 minutes and helps maintain interior air quality, especially in dusty or urban environments. Plan to replace it every 15,000–30,000 miles or as recommended by Toyota depending on driving conditions.
Location and access
The cabin air filter is tucked away behind the glove box on the passenger side of the dash. To reach it, open the glove box, release its stops or damper, and lower the box so you can access the filter housing on the back wall of the compartment. A rectangular access door covers the filter in most trims.
What you'll need
Prepare a few basic items to make the replacement smooth:
- New cabin air filter compatible with a 2016 Prius
- Optional: screwdriver (flathead or Philips) if your trim uses screws
- Clean cloth or compressed air for debris cleanup
With these on hand, you’re ready to proceed with the replacement steps described below.
Replacement steps
Follow these steps to access and replace the cabin air filter in a 2016 Prius. The process is similar across 2016–2020 Prius models.
- Park safely, turn off the engine, and open the glove box.
- Gently squeeze the sides of the glove box inward to release the stops and let the box drop down or remove the damper if needed.
- Locate the rectangular filter housing door on the back wall of the glove box area and open it.
- Remove the old filter by pulling it straight out. Note the orientation—filters are typically marked with arrows indicating airflow toward the cabin.
- Clean the housing with a clean cloth or use compressed air to remove any dust or debris.
- Insert the new filter with the arrows pointing toward the cabin, ensuring it sits flat in the housing.
- Close the housing door and reassemble the glove box by lifting it back into place and re-engaging the stops or damper.
After replacement, run the HVAC on a few fan speeds to confirm unobstructed airflow and a proper seal around the housing.
Summary
