The Solarbag purifies 3.5 L of drinking water via a sunlight-activated, nanotechnology-coated mesh.
SolarBag disinfects chemical contamination in drinking water via a nanotechnology-coated mesh, which is activated by the sun. The SolarBag is compact in size and relatively lightweight making it suitable to ship to areas of humanitarian need.

FAQ section on Solarbag’s website
Unknown. Since the product handles contaminated water, any defects will most likely compromise the product and require the product to be disposed of.
Removes the following from water: Bacteria, Viruses, Protozoa, Herbicides, Pesticides, Herbicides, Petrochemicals, Pharmaceuticals, Arsenic, Lead, and Mercury. The self-cleaning mesh does not clog, and the water tastes clean after disinfection. Eliminates 99.9999% of bacteria, 99.99% virus, 99.9% protozoa, removes heavy metals, and destroys man-made chemicals.
92% of SolarBags functioned normally throughout the first 6 months of trial use. 77% were fully functional even after 6 months.
Puralytics field testing conducted in Malawi from 2013 and third party testing. Interview with representative
SolarBag is unsafe if there is a leak or the activated mesh is compromised. If water is highly turbid or contains sediment, filtering the water or allowing sedimentation to occur will improve the resulting water quality. Saline waters need to be desalinated in conjunction with the use of the SolarBag, as it will not remove salt.
For overcast days, the SolarBag comes with Pur-Blue Process Timer, a blue indicator dye that turns clear once the water has been purified. A single drop per bag indicates whether water is ready for drinking.
