The cabin air filter in a 2008 Nissan Altima is located behind the passenger-side glove box. Access it by lowering the glove box and removing the filter housing cover to replace the filter.
In most 2008 Altima models, the filter is a rectangular pollen/cabin filter mounted in a housing directly behind the glove box on the passenger side. The exact method to reach it can vary slightly by trim, but the general steps involve opening the glove box, releasing its stops, and removing a small access panel to reach the filter.
Location and access
The following steps describe how to expose the cabin air filter and replace it.
- Park on a level surface, turn off the engine, and engage the parking brake.
- Empty the glove box and, if present, detach the glove box damper so the box can drop down freely.
- Gently press in on the sides of the glove box to release the stops and lower the box until it rests down the knee bolster area, revealing the filter housing behind a rectangular access panel.
- Give the access panel a firm pull or slide its latches to remove it and expose the cabin filter.
- Carefully pull out the old filter, noting the airflow direction (arrows on the filter should point toward the rear of the vehicle).
- Insert the new filter with the arrows pointing in the correct direction, ensuring it sits flat in the housing.
- Reinstall the housing cover, raise the glove box back into position, reattach the damper if you removed it, and replace any items you removed from the glove box.
Replacing the filter is a straightforward maintenance task that helps keep the interior climate control effective and reduces odors and pollen ingress.
What you’ll need
Before you begin, gather these items to ensure a smooth replacement process.
- New cabin air filter compatible with a 2008 Nissan Altima
- Flashlight or dedicated inspection light
- Small screwdriver or trim tool (optional, if needed to release clips)
- Clean rag or microfiber cloth
Having the right filter on hand and a light sources will make locating and replacing the filter quick and easy.
Tips and notes
- Some Altima trims use a simple snap-in housing; others use small screws or tabs. If screws are present, remove them carefully and keep track of them for reassembly.
- Always replace the cabin filter with the airflow arrows pointing toward the rear of the vehicle. A misoriented filter can reduce filtration efficiency and airflow.
Summary
In the 2008 Nissan Altima, the cabin air filter sits behind the passenger-side glove box inside a small housing. Access involves lowering the glove box, removing a panel or damper, and replacing the filter with the correct orientation. This routine maintenance helps maintain interior air quality and HVAC efficiency, typically scheduled every 12,000–15,000 miles or per your owner’s manual.
