On the w210 it uses BOTH, as I said there is ALSO a paper filter element behind the glovebox.
Info on removing the glovebox

try this post and click the Bosch site link it'll show the location of the charcoal filters (there are two). When you order, you order one SET of filters - order ONE you get both charcoal filters. THEN you must also order the PAPER filter click on "show all" in Faslane above. For your car here is the info:

part No. R2061-66069 ACC Cabin Filter Set (PAPER) $21.70

Part No. R2061-77121 ACC Cabin Filter Set (CHARCOAL) $132.29

Both are inside the car. Tools needed: philips screwdriver.
