Abstract: A mist-refining humidification system for humidifying a controlled environment which incorporates a mist generation means totally immersed within a flowing air stream and a multi-direction, mist migration path to deliver a very fine mist to a humidity controlled environment. In accordance with the most preferred embodiments, the mist-refininig humidification system comprises a mist nozzle assembly positioned within the controlled environment and totally immersed within a laterally flowing air stream to deliver a mist into a mist-refininig assembly. The mist-refining assembly, also located within the controlled environment, defines a mist migration path that includes changing path directions to aid in removing and breaking up larger droplets found in the mist.
