Technically speaking, the WaterMill is an atmospheric water collection device that condenses water vapor and purifies it. In English: It’s a home appliance that makes drinking water for your whole family - using only air…. Here’s how it works: The system draws in moist, outside air through an air filter. The moist air passes over a cooling element, condensing the moist air into water droplets. This water is then collected, passed through a specialized carbon filter and is then exposed to an ultraviolet sterilizer, eliminating bacteria… The result? You have taken control of your family’s drinking water needs… Once drinking water is created, it goes to the point of use devices in your home: your refrigerator, spigot, water cooler or backsplash dispenser.
