is there a cabin filter in a 2004 Kia Sorento and if so how do you get to it?

What is your question?

Whenever I park my car in a certain spot for a long period of time, when I turn on the air conditioner, it seems to blow the smell, from where I have been parked, through the vents. Very unpleasant odors sometimes. Might be earthy moldy smell or stale air smell, etc... so just wondering if there is a filter for the air conditioner in my 04 Kia Sorento?
