This project is to develop a standardised process of localisation, sourcing, manufacturing of solar powered water filters.

Description[edit | edit source]

The solar powered water filters were initially designed in Bangladesh, with a manufacturing manual and a product guideline for all the open source makers in Ukraine to support survivors in need of drinking water in the conflict zones in Ukraine
