1. A method of aroma therapy comprising;

  • providing an atomizer comprising an eductor and a separator, the atomizer being connected directly to a reservoir and to a pump anchoring the atomizer to a supporting surface;

    the providing an atomizer wherein the eductor comprises a nozzle having a minimum effective diameter discharging the flow therethrough and into an aperture spaced therefrom a distance of from about one to about 10 times the minimum effective diameter;

    adjusting an electronic controller to control at least one of a duration of operation and a duration of a delay between periods of operation of the pump;

    operating the pump to pressurize ambient air into a flow through the atomizer;

    educting a liquid directly from the reservoir into the flow;

    atomizing the liquid into droplets by the educting and by colliding against a wall of the separator;

    separating the droplets by size;

    recovering comparatively larger droplets into the reservoir;

    passing comparatively smaller droplets from the atomizer out through the separator with the flow; and

    simultaneously limiting net outflow of the liquid and decreasing mean droplet size by selectively controlling by a user the duty cycle of the pump.
