Element Four will soon begin to market its WaterMill that turns air in to water via condensation. Uses include refrigerator water dispensers, your spigot, water coolers, up to 12 liters of water a day.
The atmosphere contains 4 to 25 grams of water vapor per cubic meter, while the WaterMill can change 10% to 40% of that to liquid. Water vapor is constantly replenished by Earth’s natural cycle, so extracting water from the air can continue indefinitely without impacting local ecosystems.
