The Watermill is an atmospheric water collection device that condenses water vapor from the air into liquid water by drawing in warm, humid air, cooling it over coils to condense the moisture, collecting and filtering the water, and sterilizing it with UV light. It functions effectively in temperatures over 15.5°C and relative humidity over 30%, drawing in air, condensing the moisture on coils, collecting and purifying the water through carbon filtration and UV sterilization.
