Abstract:
An end-of-faucet filter for filtering water flowing through a faucet, said end-of-faucet filter comprising:a housing having an inlet aperture for attachment to the faucet, an outlet aperture, a channel extending between said inlet and outlet apertures, and a filter positioned in said channel to filter water flowing therethrough;a flow reactive device positioned in the channel and exposed to the flowing water;a signal generating member positioned on the flow reactive device;a sensor positioned proximate to the flow reactive device, and being sensitive to the movement of the signal generating member, the sensor generating a flow signal corresponding to water flow in the channel;an output device for indicating when the filter is useable; anda controller, including a threshold, receiving the flow signal and comparing the flow signal to the threshold, the controller activating the output device when the flow signal exceeds the threshold.
