As long as there is air, we can create water. 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 pure and potable. AWGs are useful where pure drinking water is difficult or impossible to obtain, because there is always a small amount of water in the air.
Air 2 Water Solutions AWGs has an inbuilt filtration system that produces pure potable water at about PH 7. The filters are as follows:
Polypropylene filter (PP)
Carbon block water filter cartridge (CTO)
Reverse osmosis (RO)
T33 Water Filter
Ultra Violet Germicidal Irradiation (UV)
Research has also developed AWG technologies to produce useful yields of water at no cost with a solar power kit.
