摘要： A method of repeatedly indicating to a user of an appliance that a water filter unit operably connected to the appliance has passed its useful life and a filter unit configure for use in connection with the method where the filter unit includes a fluid flow impeding system within a housing of the filter unit; engaging the filter unit with the appliance; measuring the volume of water treated by the filter unit; activating a fluid flow impeding system contained within the housing of the filter unit; and repeatedly indicating to a user that the maximum volume of water the filter unit has been designed to treat has been surpassed and the filter unit should be replaced by repeatedly delivering a normal flow rate of water from the dispenser of the appliance and thereafter slowing the flow of water from the dispenser of the appliance.
