The outer face of the nozzle is arranged so that a person can position his or her nose near the openings. Each of the smaller openings is associated with a different one of the odor compartments and is isolated from the others and from the central opening so that the odor from only one odor compartment can be emitted through only one of the smaller openings. A fan within the housing is adapted to pass fresh air through the central opening. And an air pressure source selectively forces one or more of the odorants through their respective odor compartments and …
