In 12 hours most of the other distilling machines produce only about 1 to 1-1/2 gallons of water. The Jon Ellis Machine will produce 5 gallons in 12 hours. Even the machines which makes water from of air and that is if your air is at 100% humidity will produce 5 gallons in 24 hours. so their machine produces 2.5 gallons in 12 hours.
The later machine works as a dehumidifier and catches and filters the water. However there is no erasure of the memory markers in the water as the JELWM does.
by and by John Ellis makes the best water distilling machines
