Abstract
A faucet mounted filter device includes a horizontally disposed cylindrical part for housing a replaceable filter cartridge and a horizontally disposed arm part extending radially from the cylindrical part which has a connector on its upper side for releasable connection to a downwardly discharging water faucet. A window is provided in the cylindrical part through which the water filtration capacity gallonage is visible. A built in microprocessor with a counter delivers data to a read-out at the front end of the cylindrical part which displays the gallonage of water filtered by the filter cartridge. A sensor connected to the microprocessor senses flow of filter water and installation and removal of the cartridge causes the counter to start counting and to return to zero, respectively.
