The suitcase-sized device, which requires less power to operate than a cell phone charger, can also be driven by a small, portable solar panel, which can be purchased online for around $50. It automatically generates drinking water that exceeds World Health Organisation quality standards. The technology is packaged into a user-friendly device that runs with the push of one button.
Unlike other portable desalination units that require water to pass through filters, this device utilises electrical power to remove particles from drinking water. Eliminating the need for replacement filters greatly reduces the long-term maintenance requirements.
