In Cabin Air Filter Replacement?

I was wondering if someone could tell me how to change the in cabin air filter on a 2004 Quest? I took the glove box out, and I did not see an air box that the filter would go into. It must be hidden in there, or I am blind! Thank's for your help.

Now that your glove box is out, look in the center of the van, behind the console. There is a slender black access panel. Maybe 1" x 6"?.
