UNU is a sustainable and autonomous water purifier, enabling access to clean water in low-resource communities. Made with simple and natural materials, UNU uses only two steps in the purifying process: evaporation and condensation. By placing burning wood (or a similar heat source) underneath the UNU, the contaminated water evaporates. These rising vapours then clash with the cooler cover, enabling condensation. The condensed and purified water then drips into a smaller, internal container. By empowering low-resource areas to purify their own water, UNU can transform the lives of the millions of people currently living without access to a clean water supply.
