It would be nice to know the year of your Nissan Altima. For Nissan 2000 Altima GXE the air filter is located right next to the battery. Just push off the 4 clips that hold the top of the filter housing and pull the top off just enough to remove/replace the air filter. Close it and and pull the clips back on.
