<p>An apparatus for purifying water, that includes a frame, in connection with which is arranged a primary space for water to be filtered, secondary space for filtered water and a filter. The filter is arranged to filter water, that is driven by gravity from the primary space existing in the frame to the secondary space, wherein the filtering influence of the filter is based essentially on a thin filtering film made of plastic based material. Essentially underneath the primary space is arranged an accessory space for the filtering means, that is in connection with the primary space and that has an essentially smaller cross-section than the same, in order to keep the filter surrounded by unclean water in the auxiliary space of the primary space, being limited from the secondary space, totally separate from the secondary space.</p> |
