Thanks, Chameleon-kat, for the info.
I would have never found it, otherwise. The Buick, too, has the in-cabin filter in the glove box. Open the glove box, look in the back. You will see an access door. It will come off completely, revealing yet another door. Open that one and the filter is right there. Just pull it out. After you remove the 1st one, the 2nd one is to the left...just slide it right and pull it out. They are to be inserted in a specific direction (up/back), but are marked on the plastic part of the filter to show you how they are to be inserted. Extremely easy...for once!
