Olivier de Gruijter is an Amsterdam-based industrial design engineer and public speaker. After witnessing water scarcity first-hand while traveling Olivier designed JERRY. This device enables people to filter water in their jerry cans, as the water source may be contaminated, or the jerry can itself may not be clean, or both. JERRY contains two filters, eliminating over 99.999% of bacteria, parasites and dirt from the water. A glass is filled in only three pump strokes, allowing young children and elderly to filter water with ease.
