A point-of-use water filtration system having an idle mode , a filtration mode , and a recirculation mode , the water filtration system comprising: a feed water inlet ; a pump in fluid communication with the feed water inlet via a feed water line ; a semi-permeable membrane having an upstream side and a downstream side, a first portion of the upstream side in fluid communication with a membrane inlet and a second portion of the upstream side in fluid communication with a concentrate outlet , and the downstream side in communication with a permeate outlet ; a permeate line in fluid communication with the permeate outlet and a filtered water outlet ; a concentrate line in fluid communication with the concentrate outlet; a flow path configured to selectively connect the permeate line to the feed water line; wherein the flow path includes a valve selectively actuatable by a controller ; and the controller is configured to anticipate demand for the filtration mode based on water consumption operator habit information stored in a memory of the controller when the water filtration system is in the idle mode and to operate in the recirculation mode to recirculate water in the permeate line through the pump and the semi-permeable membrane in response to the anticipated demand for the filtration mode; wherein the controller is further configured to command the valve positioned in the flow path to open in response to the anticipated demand for filtered water, where the valve is in a closed position in the idle mode and in the filtration mode, and the valve is in an open position in the recirculation mode; and to command the pump to pump the water in the permeate line through the semipermeable membrane in the filtration mode and in the recirculation mode, the pump being turned off in the idle mode. a feed water inlet ; a pump in fluid communication with the feed water inlet via a feed water line ; a semi-permeable membrane having an upstream side and a downstream side, a first portion of the upstream side in fluid communication with a membrane inlet and a second portion of the upstream side in fluid communication with a concentrate outlet , and the downstream side in communication with a permeate outlet ; a permeate line in fluid communication with the permeate outlet and a filtered water outlet ; a concentrate line in fluid communication with the concentrate outlet; a flow path configured to selectively connect the permeate line to the feed water line; wherein the flow path includes a valve selectively actuatable by a controller ; and the controller is configured to anticipate demand for the filtration mode based on water consumption operator habit information stored in a memory of the controller when the water filtration system is in the idle mode and to operate in the recirculation mode to recirculate water in the permeate line through the pump and the semi-permeable membrane in response to the anticipated demand for the filtration mode; wherein the controller is further configured to command the valve positioned in the flow path to open in response to the anticipated demand for filtered water, where the valve is in a closed position in the idle mode and in the filtration mode, and the valve is in an open position in the recirculation mode; and to command the pump to pump the water in the permeate line through the semipermeable membrane in the filtration mode and in the recirculation mode, the pump being turned off in the idle mode. <EOS>
