Making Water from Air

The DewPointe DH9 Atmospheric Water Purification System

This water cooler looking device extracts water vapor from the air and converts it into water. The third world applications for drinking water seem endless, but how realistic is this device. Here are a few quick facts about the device:

• Developing nations in need of clean drinking water usually have unreliable electrical systems. The DH9 requires 80 Watts while idle, and 500 Watts while actively processing water from air.
• The machine works best in more humid atmospheres. In dryer desert like climates that have an average of 30% humidity, the DH9 can produce 2.5 gallons of water and up to 3 times as much in more humid areas.
• The DH9 cost $1600, making it way to expensive for developing nations to expand in long term Air to Clean Water programs.

Here is a closer inspection of the DH9 and how it works:

STAGE 1: Air Filtration

The first electrostatic air filtration stage removes dust, pollen, mold and other airborne contaminants as humid air enters the Dewpointe^®. Atmospheric water production immediately eliminates 95% of contaminants found in municipal ground water.

STAGE 2: Chilling the Air

The airflow through the filter system is rapidly chilled to “dew point”. This is the temperature at which the potentially unlimited water in the air transforms from a gas to a liquid.

STAGE 3: Condensation

Condensed moisture collects on the specially designed coils, which are covered with a FDA approved food-grade coating to prevent potential metal pollution. Once the Dewpointe^® has completed the moisture “extraction” process, the water is delivered to an advanced multi-stage filtration system.

STAGE 4: Purification

The water passes through 10 specialized filters, including a proprietary activated carbon filter, a sediemnt filter, two carbon filters, a zero-waste R.O. filter, and a powerful UV light sanitation system. This comprehensive purifying system provides unparalleled removal of contaminants and microorganisms. At this point, the Dewpointe^®’s water is 99.99% pure.

STAGE 5: Water Temperature Optimization

The hot & cold water lines pull from a sealed stainless steel holding tank, providing chilled and hot water on demand. In just five stages, the Dewpointe^® transforms atmospheric moisture into delicious, rain-fresh drinking water!
