Apparatus for purifying water, comprising, in combination with a supporting housing and with power means, an unpurified water feed inlet and a purified water dispense outlet, an interchangeable filter (50) having depth filter layers and microporous membrane means interposed between said inlet and said outlet, means for driving the water through the filter at a constant flow rate, means for counting the time passed from the installation of the filter, means for monitoring, with a desired accuracy, the volume of water which has flowed through the filter, and constant flow, and usage controlling device for alerting the user when the data acquired by said counting and/or said monitoring means have reached a corresponding threshold value or any one of a plurality of successively increasing, predetermined threshold values; and preferably, means for automatically preventing the flow of water through the filter when the data acquired by said counting and/or said monitoring means have reached the corresponding threshold value or the highest of said plurality of the corresponding threshold values.

Cette invention se rapporte à un appareil purificateur d'eau, qui comprend, en association avec un logement de support et un organe d'alimentation, une entrée d'eau non épurée et une sortie de distribution d'eau épurée, un filtre interchangeable (50) comportant des couches de filtre de profondeur et une membrane microporeuse placées entre l'entrée et la sortie, un moyen d'entraînement de l'eau à travers le filtre à un débit constant, un moyen de mesure du temps s'écoulant à partir de l'installation du filtre, un moyen permettant de contrôler avec la précision souhaitée le volume d'eau qui traverse le filtre, et l'écoulement constant, et un dispositif de contrôle de la consommation, qui avertit l'utilisateur lorsque les données acquises par lesdits moyens de mesure et/ou de contrôle ont atteint une valeur seuil correspondante ou une valeur parmi plusieurs valeurs seuils prédéterminées progressivement croissantes; et de préférence un moyen servant à empêcher automatiquement l'eau de s'écouler à travers le filtre, lorsque les données acquises par ces moyens de mesure et/ou de contrôle ont atteint ladite valeur seuils correspondante ou la plus haute desdites valeurs seuil correspondantes.
