Does anyone know if, where ,how, what it has one and how easy it is to change if it does?

Yes they do have a cabin filter. It is in the glovecompartment. there is a little door in there, u slide it up, then there is another rectangle cover that u have to pull off. after that, there is a tray type thing with the filter in it, that just slides out. You can't just clean it, you have to replace it. I have found them online for about 10 bucks. Good luck :-)
