Abstract

The invention relates to a filtering device, comprising an inlet (1) and an outlet connection (2), a substantially cylindrical first filter (20, 40) connected with the inlet connection (1), which first filter comprises a cavity (21) extending along its cylinder axis, and a filtration membrane module (30) connected with the outlet connection (2), which is at least partially accommodated in the cavity (21) of the first filter (20, 40), the first filter (20, 40) and the filtration membrane module (30) being connected in series and comprising a bundle of capillary filtration membranes (32) whose open ends connect to the outlet connection (2). The exterior cylinder mantle of the first filter (20, 40) forms an inlet, and the interior mantle of the first filter (20, 40) enclosing the cavity (21) surrounding the cylinder axis forms an outlet for the first filter (20, 40). The first filter (20, 40) comprises a block of activated charcoal (20) which is formed by means of moulding. The filtration membrane module (30) comprises a module housing (31) embodied as a perforated tube surrounding the capillary membranes (32), and positioned substantially free from the interior mantle of the first filter (20, 40) surrounding the cavity (21). Around the block of activated charcoal (20) a felt-like filter (40) folded in concertina fashion is provided as a first filtering stage, with the folds disposed parallel to the cylinder axis.
