1. A peritoneal dialysis system comprising:
a cycler configured to pump peritoneal dialysis fluid; and
a disposable set configured to receive the peritoneal dialysis fluid pumped by the cycler, the disposable set including a filter having:
a fresh peritoneal dialysis fluid pathway,
a one-way valve located at or near an exit end of the fresh peritoneal dialysis fluid pathway,
a used peritoneal dialysis fluid pathway placed in parallel with the fresh peritoneal dialysis fluid pathway, and
a membrane located along the fresh peritoneal dialysis fluid pathway and configured to filter the peritoneal dialysis fluid,
wherein the one-way valve is configured such that (i) fresh peritoneal dialysis fluid is directed to flow from the cycler towards a patient through the membrane via the fresh peritoneal dialysis fluid pathway, and (ii) used peritoneal dialysis fluid is directed to bypasses the membrane via the used peritoneal dialysis fluid pathway.
