Yes. The 2015 Nissan Altima is equipped with a cabin air filter, also known as a pollen or dust filter, designed to clean air entering the cabin through the HVAC system.
What a cabin air filter does
The cabin air filter protects occupants by filtering particulates from outside air before it enters the passenger compartment. It helps improve interior air quality and can contribute to better HVAC performance.
Cabin air filters trap common pollutants such as dust, pollen and mold spores, and some models use activated charcoal to help reduce odors.
- Traps dust, pollen and other particulates from outside air
- Improves interior air quality for occupants
- Can help reduce odors, especially if a charcoal filter is used
In short, keeping the cabin air filter clean supports healthier cabin air and HVAC efficiency.
Where to find it and how to access
On the 2015 Altima, the cabin air filter is located behind the glove box. Access requires lowering the glove box and removing the filter housing cover.
- Turn off the engine and remove any items from the glove box.
- Squeeze the sides of the glove box inward or use the stops to let it drop down, exposing the filter housing.
- Detach the filter housing cover to reveal the old filter.
- Remove the old cabin air filter from the housing.
- Clean out any debris from the housing before inserting a new filter.
- Insert the new filter with the arrows pointing toward the HVAC system (direction of airflow).
- Reattach the housing cover, lift the glove box back into place, and close it.
After replacement, ensure the glove box is secured and the vents operate normally when the system is turned on.
Replacement intervals and practical tips
Regular maintenance of the cabin air filter helps maintain air quality and HVAC performance. Here are general guidelines and tips:
- Typically replace every 12 months or 12,000 miles, whichever comes first. Check your owner's manual for the exact interval for your trim and region.
- In dusty, urban, or high-traffic conditions, consider replacing more frequently.
- Common symptoms of a dirty filter include reduced airflow, musty odors, and increased pollen or dust blow from the vents.
Following these guidelines can help ensure the interior remains comfortable and the climate control system functioning well.
Summary
The 2015 Nissan Altima is equipped with a cabin air filter. Access is behind the glove box, and replacement is a straightforward DIY task. Regular replacements, typically once a year or every 12,000 miles, keep the interior air clean and the climate control system functioning properly.
