AquaVallis is a new nanofiber-based electropositive filter material that allows water purification by removing viruses and bacteria of size many times smaller than the average pore size of the filter.

According to the World Health Organization data, 80 % of all infectious diseases in the world are caused by unsatisfactory quality of water or poor hygiene and sanitary conditions due to its shortage. The ever-increasing deficiency in water supply will aggravate the problem and its ubiquity will lead to stable high growth of demand for water purifying devices and facilities.
