Changing the cabin air filter in your MINI is a very quick but neccessary thing to do each year. Simply start by removing the cabin air filter cover from the underside of your glovebox.

Pull the factory cabin air filter out making note of which way the filter was positioned. Slide in a new Electrostatic Cabin Air Filter or Carbon Cabin Air Filter and reinstall the cover.

Below is a couple images of a dirty cabin air filter from a MINI with only 5,000 miles. You can see how dirty it has become in onlyl 5,000 miles, imagine what one would look like after a full year or two worth of driving.
