The Watermill is an ingenious little device that attaches to the side of your house, sucks in humid air and converts it to water, much like the Max Water we've seen before. It then filters the water until it's drinkable, giving you free, fresh, clean water to drink.
By sucking up water from outside rather than inside, it gathers cleaner air and avoids drying out your house, which is a plus. It can provide up to 12 liters of water a day, water that's clean enough to cook with or drink, which is great if you've got crappy tap water or have big water jugs delivered. Why pay for water when it's just out there, clogging up the humid air? Might as well take advantage, right?
