The cabin air filter on a 2020 Nissan Armada sits in the HVAC housing behind the glove box. Access is gained by lowering the glove box and removing a small rectangular panel to replace the filter.
The following guide explains the exact location, what you’ll need, and step-by-step instructions to replace the filter, along with maintenance tips to keep the interior air clean.
Location and access
The cabin air filter is housed in the HVAC unit behind the glove box. To reach it, you’ll drop the glove box by releasing its sides or damper, then remove the rectangular access panel to reveal the filter.
How the filter is accessed
Behind the glove box there is a cover for the cabin air filter. Removing this cover exposes the filter for replacement. The process is designed to be done with hand tools only, without special equipment.
What you’ll need
Before you start, gather the items you’ll use during replacement:
- New cabin air filter compatible with the 2020 Armada (check your owner’s manual or parts catalog for the correct part number)
- Gloves (optional)
- Lint-free cloth or paper towel for cleaning the housing
Having the right filter and a clean workspace helps ensure a proper fit and airflow.
Step-by-step replacement
Use these steps to access and replace the cabin air filter. The steps assume a standard cabin air filter and typical Armada interior layout.
- Park the vehicle on a level surface and turn the ignition off. If the vehicle was running, wait a few minutes for the HVAC components to cool.
- Open the glove box and remove its contents.
- Gently press the sides of the glove box inward to release the stops, and let the glove box drop down fully. In some models you may need to detach the glove box damper on the right side.
- Look behind the glove box for a rectangular access panel labeled with a cabin air filter symbol or simply a tabbed cover. Remove the cover by pulling on the tabs or lifting the edge.
- Pull out the old cabin air filter. Take note of the orientation of the arrows on the filter, which indicate airflow direction toward the HVAC housing.
- Insert the new filter with the arrows pointing toward the HVAC housing (same orientation as the old filter).
- Reinstall the access panel securely, then raise the glove box back into place and reattach any damper or stops you removed.
- Close the glove box and start the vehicle. Run the HVAC on fresh air for a few minutes to confirm airflow is even and there are no unusual noises.
When completed, ensure the filter is seated properly and the glove box operates smoothly.
Maintenance and replacement intervals
Nissan generally recommends replacing the cabin air filter every 12 months or 12,000 miles, or sooner if you drive in dusty or high-pollen conditions. Check your owner's manual for the precise interval for your trim and region.
Summary
For the 2020 Nissan Armada, the cabin air filter lives in the HVAC housing behind the glove box. Access is gained by lowering the glove box and removing a small cover; replace with a filter oriented so the arrows face into the HVAC. Regular replacement helps maintain cabin air quality and HVAC performance.
