A filter apparatus is provided which includes a first filter membrane element (40a), and a second bacterial filter membrane element. The first viral filter element (40a) is capable of treating water at a first second flow rate and is adapted to remove contaminants which are larger than a first size, while the second bacterial filter element (40b) is capable of treating water at a secon, higher flow rate and is adapted to remove contaminants which are larger than a second contaminant size. The first and second filter elements (40a), (40b) may be commonly housed within a sealed housing. An accumulating vessel (60) is placed in fluid communication with an outlet of the first filter element (40a) and an outlet of the second filter element (40b). The filter apparatus includes a duck bill type check valve (75) made of an antimicrobial material intermediate the second filter element (40b) and a dispensing faucet (70).
L'invention concerne un appareil de filtrage qui comporte un premier élément membranaire de filtrage viral (40a) et un second élément membranaire de filtrage bactérien. Le premier élément de filtrage viral (40a), qui peut traiter l'eau à un premier débit, est conçu pour évacuer des contaminants dépassant une première dimension, tandis que le second élément de filtrage bactérien (40b), qui peut traiter l'eau à un second débit plus élevé, est conçu pour évacuer des contaminants dépassant une seconde dimension de contaminant. Les premier et second éléments de filtrage (40a), (40b) peuvent être d'ordinaire logés dans un logement étanche. Un récipient collecteur (60) est placé en communication fluidique avec une sortie du premier élément de filtrage (40a) et une sortie du second élément de filtrage (40b). L'appareil de filtrage comporte également un clapet du type bec de canard (75) à base de matériau antimicrobien entre le second élément de filtrage (40b) et un robinet de distribution (70).
