Element Four® introduces the WaterMill, a self-regulating air-to-water generator for residential use. The unit provides a clean, sustainable and cost-effective source of water for drinking and cooking, producing 13 quarts (12 liters) of water per day. It mounts to the exterior of the home, drawing water from the air outside into POU systems inside, maximizing water production, while minimizing energy consumption.www.elementfour.com
