Abstract
Described is a water purification device having an intake funnel (1), a sleeve (2) which is sealingly connected thereto and an insert which has approximately cylindrical side walls (4), a filter cover (5) and a filter bottom (6) and in which a granulate-type purification agent can be introduced. So that any gases and/or air which accumulates no longer impede the flow of water to be purified through the filter bottom (6), in accordance with the invention it is provided that the filter bottom (6) has an air collecting space (7) which is extended upwardly at least partially towards the side wall (4); wherein preferably the air collecting space (7) is in the configuration of half-tubes (11) which are open downwardly and outwardly of the bottom and which are connected to each other and to a chimney-like half-tube (12) which extends over the side walls (4).
