Do you own a W211 Mercedes E320 E500 E350 E550 or E55? Confused about the cabin air filter or filters? Even the parts guys don't seem to get it right. There is so much confusion concerning which filter or filters to order for which models! Link to purchase filters with video instructions: mercedessource.com/store/sear... This is a longer video than I had intended but it took a while to explain it clearly. No wonder there is so much confusion floating around the internet. Much of the advice you see on many of the forums is not correct or very confusing. I gave it my best shot.
