Having a flashlight available improves visibility in the glove compartment area, and wearing disposable gloves helps keep your hands clean during the process .

Step-by-Step Replacement Instructions

Step 1: Accessing the Filter Housing

Begin by opening your glove compartment and removing all contents. Look for stops or dampeners on either side of the glove box that prevent it from lowering freely. Depending on your specific Altima model, you may need to disconnect a lever or cord that limits how far the glove box can extend . Once these limitations are addressed, press inward on the sides of the glove box to clear the retention tabs, allowing the glove box to lower completely and providing access to the filter housing behind it .

Some Altima models may require removing screws or clips holding the glove box in place. If present, these fasteners are typically located along the inner edges of the glove box compartment . Carefully remove any screws and set them aside in a safe location where they won't be lost during the procedure .

Step 2: Removing the Old Filter

With the glove box lowered or removed, you'll see a rectangular plastic cover housing the cabin air filter. This cover is typically secured with clips or tabs on one or both sides . Gently squeeze the tabs to release the cover and set it aside. Take note of how the old filter is oriented before removing it—most filters have airflow arrows indicating proper direction .

Carefully slide the old filter out of its housing, being mindful that accumulated debris may fall out during removal . To prevent this debris from entering your HVAC system, consider having a vacuum cleaner with a brush attachment handy to clean the filter housing before installing the new filter .

Step 3: Installing the New Filter

Before inserting the new filter, compare it with the old one to ensure identical size and shape. Check the airflow arrows on the new filter—these should point in the same direction as the arrows on the old filter you removed . Typically, the arrows should face toward the rear of the vehicle or downward, but verifying against the old filter's orientation provides certainty .

Slide the new filter into the housing, taking care not to force it if it feels resistant. The filter should fit snugly without gaps around the edges . Once properly seated, replace the filter cover and secure it with the clips or tabs you released earlier.
