This document summarizes a chemical-free, membraneless water filtration solution that can filter 1 liter of water in 5 minutes. It removes particles down to the sub-micron scale from various water sources, including E. coli and turbidity. The solution has applications for portable water treatment, homes, apartments, restaurants, ponds, and more. It provides clean water access for over 850 million people and is competitive against other filtration methods by being portable, high throughput, environmentally friendly, and not requiring fine feature fabrication or chemicals. The solution has undergone prototypes and field trials, won awards, received funding, and has patent applications filed.
