1. A nasal irrigation device, comprising:
a source of irrigant;
an effluent receptacle; and
a housing located between the source of irrigant and the effluent receptacle, the housing comprising:
a vacuum source for applying a relative vacuum to the effluent receptacle;
a nasal interface comprising first and second nozzles configured to simultaneously contact first and second nostrils, respectively, of a device user's nose; and
a fluid passageway for communicating the irrigant from the source of irrigant to the effluent receptacle via a nasal cavity of the device user, wherein the fluid passageway comprises a supply conduit from the source of irrigant to the first nozzle and an effluent conduit from the second nozzle to the effluent receptacle, and wherein the supply conduit is separate and distinct from the effluent conduit.
