Clean water is hard to access in a lot of places around the world. Sometimes water is accessible but not potable, this problem inspired a graduate student to create an easy to use way to purify water using something similar to a hamster ball.
Liowâ€™s design was driven by a need to help the 900 million people around the world who lack access to safe drinking water. Over two million children die annually from preventable causes, triggered largely by contaminated water. It is an increasing problem in developing nations due to rapid urbanisation and population growth.
â€˜After visiting Cambodia in 2008, and seeing the immense lack of everyday products we take for granted, I was inspired to use my design skills to help others,â€™ Mr Liow said.
Mr Liowâ€™s simple but effective design is user-friendly and durable, with a weather-resistant construction, making it well suited to people in hot, wet, tropical climates with limited access to resources.
