Nanotech Tea Bag

Roughly 1 billion people in the world have no access to safe drinking water, and contaminated water sources kill 1.8 million people worldwide each year. Seeking to provide a solution to this problem, South African researchers have created a water-purifying nano tech tea bag that costs half a cent. Portable, instantly effective and with no chance of re-contamination. In order to activate the tea bag, the user places it into the neck of a water bottle and then drinks water that passes through it. As water passes through the bag, activated carbon removes various chemical compound and impurities while the biocides on the nano fibers quickly destroy microbes. Simply by passing through the filter diseased water can be made safe to drink. The design is portable and instantly effective. Marelize Botes, a microbiology researcher at South Africa‘s Stellenbosch University says, “The nano fiber will disintegrate in liquids after a few days and will have no environmental impact. The raw materials of the tea-bag filter are not toxic to humans.“ The nano fiber filter system is part of the Hope Project in South Africa, which hopes to improve the lives of millions of Africans by addressing major problems like poverty and health. South Africa’s Bureau of Standards is currently reviewing the nano fiber filter and accessing its viability. Once approved, the products could theoretically go into mass production.
