Since it is difficult, because very awkward (installation and removal), to work with and compare without carbon filter, I'm assuming that it well carries out his work, because the old filter had significant signs of wear and you saw and smelled that it was saturated.
The installation itself is device dependent, but if you do so calmly before taking a look at the instruction manual of the hood to adjust the filter change in menu properly and thus to start the filter interval again. From the fit of the filter itself, there were as to be expected no problems. Only the hood to de-energize proved more tinkering, since the plug (mounted behind the cover of the hood) could not be so easily drawn and other devices with this socket fuse circuit layers, so that not even the insurance could be easily drawn.
With a bit of searching, you can still save the odd Euro but even with this product. Since there is no real viable alternative, the manufacturer of this original part the price but certainly is rated by me as quite high, I give only 4 stars.
