How do you change the incabin air filter in a 2011 Nissan altima?

To change the in-cabin air filter in a 2011 Nissan Altima, start by turning off the vehicle and opening the glove compartment. Remove the contents of the glove box, then gently squeeze the sides to unhook it, allowing it to drop down. Locate the filter cover behind the glove box, unclip it, and remove the old filter. Insert the new filter in the same orientation as the old one, reattach the cover, and then reassemble the glove box.
