Puralytics SolarBag 3L
The SolarBag combines solar energy and nanotechnology in a compact, lightweight product that claims to destroy pathogens and chemical contaminants and remove heavy metals in water.
A nanotechnology coated mesh insert disinfects and detoxifies drinking water when activated by sunlight. A blue indicator fluid changes to clear after a few hours in the sun to indicate that the water within is pure and ready to consume.
The reusable SolarBag can treat three liters of water at a time, up to three times per day, and is reusable up to 500 times.
The SolarBag is BPA-free and claims the widest containment coverage available including bacteria, viruses, protozoa, herbicides, petrochemicals, pharmaceuticals, arsenic, lead, and mercury. It is currently undergoing the process for EPA certification.
Dan Bruce showed us Puralytics's SolarBag photochemical water purification system at Outdoor Retailer Winter Market:
SolarBag's purifying process includes photocatalytic oxidation (the sun activates the nanotechnology mesh to oxidize contaminants); photocatalytic reduction (to reduce mercury, silver, arsenic, and other heavy metals); photolysis (directly dissociates contaminants with the sun's UV light); photoabsorption (catalyst absorbs heavy metals); and photo disinfection (UV disinfects pathogens).
