Unfortunately, there was at the filter set no great description but only an illustrated folder. One should fill the filter with 0.5 L water and then air-free as possible inserting into the machine. I have it reasonably managed with a thin stream of water, and then, as usual, the filter still left something in the water are having opening upward until he was no longer air bubbles on its own after a few minutes.
If the filter is not properly filled with water and is still used in the machine, there is the, as well as in other reviews already-described phenomenon that the water possibly ends up slightly powdery activated carbon or the machine will not draw in water but only air! Additionally, it is recommended not to consume the first 2 fillings for filter change but to use for flushing so that any existing charcoal production residues or odors are rinsed.
If one pays attention to the above-mentioned problem somewhat but the filter works pretty flawlessly.
The price is, as usual with accessories, always a bit steep. But you can also save the filter, if necessary, if you already use an electric kettle with an integrated filter in the kitchen and then fills this filtered water in the ECAM tank. Would be otherwise filtered twice ....
The regular exchange of "exhausted" filter is probably also important, since otherwise could reverse the benefits of the filter and collect more pollutants and bacteria in the water .... simple hygiene care in the food industry. How often do you do that depends on the frequency of use from, is often recommended after 4 weeks, for me it's sometimes even 2 months.
Product was okay, price a bit steep, so 3 stars.
