Locating the 2019 Nissan Altima cabin air filter requires accessing the compact assembly situated directly behind the glove compartment. This component plays a critical role in maintaining in-cabin air quality by trapping pollen, dust, and road debris before they enter the ventilation system. Understanding the specific location and access procedure ensures proper maintenance and prevents unnecessary visits to the service center.
Standard Location Within the Dashboard The primary 2019 Nissan Altima cabin air filter location is behind the passenger-side glove compartment. To visualize its placement, imagine the rectangular housing of the glove box extending rearward; the filter resides in the plenum chamber directly behind this structure. This specific positioning allows the filter to intercept incoming air before it circulates through the climate control vents, ensuring that the air you breathe is processed through the filtration system. Accessing the Filter Housing Gaining access to the filter requires a specific sequence to protect the integrity of the HVAC housing. First, fully open the glove compartment door. Next, carefully squeeze the two plastic tabs located on the inner sides of the compartment, allowing the glove box to pivot downward. You must lower the unit completely so that it hangs freely; this relieves tension on the upper retaining clips and provides the necessary clearance to reach the filter door. Identifying the Filter Door Once the glove compartment is lowered, look at the back of the assembly. You will observe a rectangular plastic cover secured by two Phillips-head screws. This panel is the gateway to the filter housing. It is typically located in the center of the plenum, roughly six inches below the top of the glove box cavity. The cover often features a small tab indicating the direction for removal, usually facing downward. Maintenance and Replacement Procedure
The primary 2019 Nissan Altima cabin air filter location is behind the passenger-side glove compartment.

This specific positioning allows the filter to intercept incoming air before it circulates through the climate control vents, ensuring that the air you breathe is processed through the filtration system.
Accessing the Filter Housing
Gaining access to the filter requires a specific sequence to protect the integrity of the HVAC housing. First, fully open the glove compartment door. Next, carefully squeeze the two plastic tabs located on the inner sides of the compartment, allowing the glove box to pivot downward. You must lower the unit completely so that it hangs freely; this relieves tension on the upper retaining clips and provides the necessary clearance to reach the filter door.
Identifying the Filter Door
Once the glove compartment is lowered, look at the back of the assembly. You will observe a rectangular plastic cover secured by two Phillips-head screws. This panel is the gateway to the filter housing. It is typically located in the center of the plenum, roughly six inches below the top of the glove box cavity. The cover often features a small tab indicating the direction for removal, usually facing downward.
After removing the two securing screws, gently pull the cover straight forward to expose the filter slot. The 2019 model utilizes a standard pleated paper filter that slides out easily. When installing the replacement, ensure the arrow indicating airflow direction points toward the dashboard. Reassemble the components in reverse order, confirming that the glove compartment latches securely to avoid rattling during operation.
Signs of a Clogged Filter
Monitoring the condition of your 2019 Nissan Altima cabin air filter is essential for HVAC efficiency. A saturated filter restricts airflow, causing the climate control system to work harder to maintain the desired temperature. If you notice a decrease in air volume from the vents or detect an unpleasant musty odor when the fan is activated, it is likely time for a replacement. Regular checks every 15,000 to 20,000 miles prevent these performance issues.
OEM vs. Aftermarket Options
When sourcing a replacement, you have the option of Original Equipment Manufacturer (OEM) parts or aftermarket alternatives. The OEM filter is engineered specifically for the airflow dynamics of the 2019 model, ensuring a precise fit and optimal filtration efficiency. Aftermarket brands often provide cost-effective solutions with comparable filtration standards, but verifying the micron rating and dimensional compatibility is crucial before purchase.
Professional Inspection Recommendations
While the replacement process is manageable for DIY enthusiasts, some drivers may prefer professional assistance. A mechanic can perform the 2019 Nissan Altima cabin air filter location and replacement in under ten minutes, often as part of a routine oil change service. Seeking professional help ensures that the housing gasket remains undamaged and that the system is tested for proper airflow post-installation.
