The Clear Choice Vapor Still utilizes the same water purification cycle found in nature - evaporation, condensation and precipitation - driven by the energy of the sun.  Utilizing high-tech materials, the still captures the sun's energy and uses it to evaporate dirty or salty water from our unique insulating wick.

The moist, heated air travels upward by a natural convective process until it contacts the cooler surface of the condensing dome. There the water collects in pure droplets much as it would in a cloud.  It then slides down the dome, collecting in a sealed chamber from which the distilled water can be easily drained.

Each Clear Choice Vapor Still will make 1.5 - 2.5 liters of distilled water in a typical day of operation.
