An apparatus for purifying water, that includes a frame (1), in connection with which is arranged a primary space (1a) for water to be filtered, secondary space (1b) for filtered water and filtering means (2), which filtering means (2) are arranged to filter water, that is driven by gravity from the primary space (la) existing in the frame to the secondary space (1b), wherein the filtering influence of the filtering means is based essentially on a thin filtering film (2a) made of plastic based material. Essentially underneath the primary space (1a) is arranged an accessory space (1a1) for the filtering means (2), that is in connection with the primary space and that has an essentially smaller cross-section than the same, in order to keep the filtering means (2) surrounded by unclean water in the auxiliary space (1a1) of the primary space (1a), being limited from the secondary space (1b), totally separate from the secondary space (1b).
L'invention porte sur un dispositif de purification d'eau comprenant un bâti (1) où sont disposés: un espace primaire (1a) pour l'eau à filtrer, un espace secondaire (1b) pour l'eau filtrée, et un moyen de filtrage (2) de l'eau qui transite par gravité de l'espace primaire (1a) à l'espace secondaire (1b), ledit moyen de filtrage consistant essentiellement en une membrane mince (2a) d'un matériau à base de plastique. Sensiblement sous l'espace primaire (1a) se trouve un espace accessoire (1a1) où se loge le moyen de filtrage (2), relié à l'espace primaire, dont la section transversale est sensiblement moindre puisque limitée par l'espace secondaire (1b), et totalement separé de l'espace secondaire (1b).
