Title
(EN) A WATER FILTRATION DEVICE
(FR) DISPOSITIF DE FILTRATION D'EAU
Abstract
(EN)
A filter to remove contaminants from potable water. The filter comprises a plurality of porous layers (15,16) forming a fluid path for the water to pass sequentially from the first layer (16) through the layers to the final layer. The first layer (16) is formed of a ceramic and/or sintered material and includes a virucide. Said first layer (16) is distinguishable from an adjacent second layer (15), wherein at least one of the first and second layers (16, 15) comprises a dye material.

L'invention concerne un filtre servant à éliminer les contaminants de l'eau potable. Le filtre comprend une pluralité de couches poreuses (15,16) formant un trajet de fluide pour que l'eau passe successivement de la première couche (16) à la couche finale en passant par les autres couches. La première couche (16) est formée d'un matériau céramique et/ou fritté et comprend un virucide. Ladite première couche (16) se distingue d'une seconde couche adjacente (15), au moins une des première et deuxième couches (16, 15) comprenant un matériau colorant.
