Puralytics Solar Bag 3L
The sun provides the only power source for a complete water purification system in a portable container. The initial product provides about 3 liters of pure drinking water in 2 to 4 hours exposure to sunlight, even on a cloudy day. The clear top cover allows the optimum wavelengths of sunlight to stimulate the photocatalytic reaction; the black back material absorbs any extra sun energy to provide thermal flow across the photocatalyst. The SolarBag 3L is equipped with a large (42mm) filtered opening for filling. The purified water is dispensed through a smaller opening, compatible with many drinking and serving accessories.
