ABSTRACT:
The present invention relates to a permanent espresso filter insert for insertion into an espresso machine, the insert comprising a substantially flat filter disc which is penetrated by a plurality of filter openings substantially in the flow direction of the medium to be filtered, with a perforated disc being designed and arranged downstream of the filter disc in flow direction in such a manner that the medium to be filtered is swirled and deflected to an increased extent. With the permanent espresso filter insert of the invention, it is possible to improve the formation of the head or cream also in espresso machines having low working pressures.
