A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets.

Ultrasonic: A tray of fresh water in the airstream is excited by an ultrasonic device forming a fog or water mist. Wetted medium: A fine fibrous medium in the airstream is kept moist with fresh water from a header pipe with a series of small outlets. As the air passes through the medium it entrains the water in fine droplets.
Such dehumidification, when followed by a reheating, makes the defogging more effective and faster, for the dry warm air has a greater capacity of absorbing water from the glass at which it is directed (with respect to the moist warm air provided by the heater alone, and the dry cold air provided by the air conditioning system alone).
