I change mine every 15,000 kilometers (about 9500 miles), and each time it is DIRTY. For the $25 the filter costs, I don't consider my regiment extreme, and is the proper service interval called for by MB. I did upgrade to the charcoal combination filter, and I think it's the only one available now.
