Is the air water machine useful? What is the water production efficiency?

Useful, but the water production efficiency is very low. The principle of water production is similar to that of dehumidifier, which sucks in humid air and discharges clean water. The water-making capacity of air water-making machine mainly depends on the humidity of air environment, and the greater the humidity, the stronger the water-making capacity; Conversely, the lower the humidity, the lower the water-making capacity. Theoretically, the working humidity range needs to be greater than 25% to make water, and the air has the strongest ability to make water in the humidity environment of 60%-70%. Under the condition of low humidity, water can also be made, but the speed of making water is slow.
