yes, a great idea of them.
first time you have a litte bit more to work, but then the change is very easy, fast and ofter per year possible and a cheap one to
i changed my filter first time after 4 years
there was NO cold air in the summer and no heating in the winter
the v class looks by the change as a big cole mine, somuch black dark was in the filter.
Note:
change the filter two times in a year !! with this method its very cheap and easy !
Useful tip: Having just done the pollen filter on my right hand drive V220 Auto, I found that if the plastic slide cover to the filter is moved back, the filter itself can be teased to be partially visible (using needle nosed pliers), and then the paper element part of the filter pulled out with a combination of pliers and fingers. The plastic frame doesn't need to be removed, and I didn't need to take out the clutch srping rod, only the centre console and the soft plastic skirts in the drivers and passenger footwell (folded them back, not take them out). The whjole exercise took 20 minutes, and best of all my knuckles are still intact! Statement of the obvious but this doesnt work if you intend to replace the filter with a new one of course.
