A fluid filter assembly for a water dispensing faucet includes a housing assembly (23) that is constructed and arranged to connect to the faucet, a cover assembly (21) threadedly attachable to the housing assembly (23) for defining an interior receiving space and a replaceable filter cartridge (22) installed in the space. A plurality of reed switches (82, 99, 109) are utilized that are responsive to changes in magnetic flux in order to provide electronic indications of filter status. These indications include cartridge useful filter life, presence of a non-approved cartridge, indication of lack of cartridge, presence of a water leak and indication that the cartridge has been replaced.

L'invention concerne un ensemble filtre de fluide pour robinet d'alimentation, qui comprend un ensemble enceinte pouvant être relié à un robinet d'eau, un ensemble couvercle pouvant être relié fileté à l'ensemble enceinte et permettant de définir un espace de réception interne entre les deux et une cartouche de filtre remplaçable dans cet espace pour le filtrage de flux d'eau avant la distribution au robinet. Plusieurs commutateurs à lames répondent aux changements de flux magnétique pour donner des indications électroniques sur l'état du filtre. Certaines d'entre elles portent sur l'état de la cartouche en termes de durée utile, d'installation de cartouche non homologuée, d'absence de cartouche, de fuite d'eau dans l'ensemble, et de remplacement de cartouche par une nouvelle cartouche.
