The goods were delivered from the stock of spare parts is extremely fast. Fits easily, exchange no problem. Carbon particles, I do not see herrumfliegen, should the plastic film that protects the filter, just not necessarily ausfschneiden with the knife ;-) Before I got the part completely unpacked, I first compared the measurements with the old filter. I change these filters provide more "rare" ;-) improvement but is now announced, after I found the right one.
The Time Strip I immediately discarded after I read here that he also recommended to change the filter, if you have never or rarely used the filter (eg due to prolonged holidays).
All TOP! There are cheaper filters the same design on the market, but this seems to me to be a good compromise between expensive original and cheaper spare parts here.
