The product consists of a cartridge technology with a patented electroadsorbative media, ion exchange, and activated carbon. It works in the principle of french press mechanism i.e. filters the water just by applying a normal body weight pressure for about 15 secs. The flow rate of this product is 5L/min and provides a drinking water storage capacity of 24 oz (710 ml).

The bottle’s physical design include:

• Weight: 15.9 oz (450 g)
• Height: 10.4″ (26.5 cm)
• Diameter (at base): 3.4″ (8.6 cm)

This product works on three principal filtration technologies:

• Electro-adsorptive media: made up of triple ion charged mesh that creates a submicron trap (like a magnet) for trapping and removal of pathogens and inorganic compounds (bacteria, protozoan, viruses).
• Ultra-powdered activated carbon: made up of coconut husks that filter toxins, traps heavy metals, and industrial chemicals.
• Ion exchange: made up of silver treated zeolites that inhibit the growth of mold, mildew, and bacteria to keep the purifier fresh between uses.

The product has a 10-year warranty with a total filter capacity of 250 L for each cartridge.

Testing performed by Biological Consulting Services of North Florida, Inc determined a 99.999% reduction in parasite contamination and 99.9999% reduction in bacterial and viral contamination.

No known safety hazards are related to this product. However, users should follow some precautions provided by the company in order to increase the lifespan of the filter cartridge.
