Untapped Water Canada
An atmospheric water generator (AWG), is a device that extracts water from humid ambient air. Water vapor in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an AWG is designed to render the water potable. AWGs are very useful in locations where pure drinking water is difficult or impossible to obtain, as there is almost always a small amount of water in the air. The two primary techniques in use are cooling and desiccants.
