YUNA Yuna is a portable water purifier conceived for members of the poorest communities in third world countries who need to walk several kilometers each day in search of water. Yuna allows for ergonomic transportation of 3.5L of water that is purified along the way with its centralized water filter. This concept can also be applied to hikers, military, and disaster relief scenarios.

The valve An integrated design allows the valve lid to be used as a drinking cup. Once valve is twisted and opened, filtered water pours out in a controlled flow. Water can be dispered while Yuna is strapped to the user or when set down on it’s base.

Ideation development The ideation thought process was based around providing an ergonomic carrying method for people to transport heavy loads of water. I wanted to place an integrated water filter that would purify the water in transit, and went through the process of where it would be ideally palced. Further ideation was made taking into account the process of pouring water into the container and how the water would be dispersed when users are drinking.
