1. A nasal nebulizer, comprising:

  • (a) a main canister with a reservoir for holding fluid, wherein the canister includes at least two air exit ports;

    (b) an insert that fits within said main canister, wherein the insert includes at least two fluid channels that mate with said air exit ports of the main canister, and wherein the fluid channels are larger in diameter than the air exit ports, thereby providing a small space between the outer surface of the air exit ports and the inner surface of the fluid channels that allows fluid from said reservoir to be drawn upward between the air exit ports and fluid channels and expelled as a mist in an aerosol plume through exit holes in the fluid channels due to a venturi effect created by pressurized air from the air exit ports; and

    (c) at least one nozzle coupled to the bottom of said main canister to create at least one air chamber defined by the nozzle and said air exit ports, wherein the nozzle includes an air inlet for providing pressurize air into said air chamber.
