Is there an air filter for the air inside the car and if so, how does one replace it? on 2007 Buick Lucerne

This is not a problem as I am interested in knowing about whether or not there is an air filter for the inside the car air. I know the air gets drawn in from the outside, but would think it needs to run through a filter first.

The cabin air filter on your vehicle is under the hood, passenger side. It is recommended to replace it every year or 15,000 miles. How to replace instructions here;
