The cabin air filter in a 2015 Nissan Altima sits behind the glove box on the passenger side, inside the HVAC intake housing. Accessing it requires opening and lowering the glove box to reveal the filter housing.
Location and access
The filter is located inside the HVAC housing on the passenger side, directly behind the glove box. To reach it, you’ll need to lower the glove box and remove the filter cover, which is held in place by clips. Some trims or configurations may require detaching a small damper or panel before you can access the filter.
What you’ll need
Gather these items before you start so you can complete the replacement without interruptions.
- Replacement cabin air filter compatible with 2013–2018 Nissan Altima
- Flashlight (optional, for better visibility)
- Clean rag or towel to wipe away dust
Having these on hand will make the replacement smoother and faster.
Step-by-step replacement
Follow these steps to access and replace the filter.
- Turn off the engine and ignition. Open the glove box and empty it.
- Gently squeeze the sides of the glove box to release the stops and lower the door. If present, disconnect the dampener strap.
- Look behind the glove box for a rectangular filter housing. Unclip and remove the cover to access the old filter.
- Slide out the old filter, noting the airflow direction printed on the side (arrows should point into the cabin).
- Insert the new filter with the arrows facing the correct direction, then replace the housing cover and secure the clips.
- Raise the glove box back into place and ensure it seats properly. Reconnect any damper if it was removed and test the HVAC blower.
Replacement frequency depends on driving conditions; a typical guideline is about every 15,000 to 30,000 miles, or once a year in areas with heavy pollution, dust, or wildfire smoke. If you notice reduced airflow or odors, it’s a sign to replace sooner.
Additional tips
While the glove box approach is common, some 2015 Altimas may present slight variations in access. If you’re uncertain or uncomfortable performing the replacement yourself, consult the owner’s manual or seek help from a qualified technician.
Summary
In the 2015 Nissan Altima, the cabin air filter is housed behind the glove box on the passenger side, inside the HVAC intake. Access involves lowering the glove box, removing the filter cover, and replacing the filter with the correct orientation, then reassembling. Regular replacement helps maintain cabin air quality and HVAC efficiency.
