Abstract
An automatic filter shutoff device containing a filter, removably connected to a water container and in fluid communication with a water dispenser, the device monitors water dispensing and disables dispensing after a predetermined amount of water usage. The monitoring and disabling mechanism has a shutoff moveable between dispensing and disabling locations. The disabling location being one in which the mechanism is placed in an interfering position with the connection between the device and the water container. The mechanism automatically moves into the disabling location after the predetermined amount of water usage has occurred without interrupting water dispensing from the then connected water container. This requires that the used filter shutoff device be replaced in order to reestablish connection to a successive water container.
