Product Schematics

FAQ section on Solarbag's website

Replacement Components

Unknown. Since the product handles contaminated water, any defects will most likely compromise the product and require the product to be disposed of.

Lifecycle

The Solarbag has a dry shelf life of 7 years. Puralytics specifies a potential life for the SolarBag as 500 uses.

To dispose of the product cut the bottom of the bag open and remove the mesh insert. Dispose of the mesh insert as non-toxic solid waste, then recycle the plastic bag as Type 7 plastic.

Manufacturer Specified Performance Parameters

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.

Vetted Performance Status

92% of SolarBags functioned normally throughout the first 6 months of trial use. 77% were fully functional even after 6 months.

Safety

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.

Complementary Technical Systems

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.
