Abstract

L'invention porte sur un filtre conçu pour fournir de l'eau potable. Il comprend une cartouche munie d'une prise d'eau et d'un orifice de sortie, un matériau filtrant disposé à l'intérieur de celle-ci et formé, au moins en partie, d'une pluralité de particules filtrantes basiques mésoporeuses à faible teneur en oxygène faites de charbon activé.
