Capture the moisture that’s around you - and drink it! Plant material, soil, raw water, sea water -- all have pure water waiting to be extracted. The Airwell Distiller uses anything with moisture, evaporates and collects it. Makes 3 to 7 pints of distilled water per day. Requires no internal or external power source - operates from natural evaporation. Portable and packable. Made entirely from food grade materials.
