Tea bag cleans polluted water

A portable, easy-to-use and environmentally-friendly water filter bag that fits into the neck of a bottle – and cleans highly polluted water. “The water is cleaned right then and there when you drink from the bottle,” says the designer behind the filter, Dr Eugene Cloete, from the Stellenbosch University in South Africa. There are also plans to commercialise the filter bag into a product that can be used by outdoor enthusiasts on hiking or camping trips.
