    by PressTV

    Thanks to researchers, there is a new and cheaper way to filter water using the branches of a specific kind of tree.

    Researchers from the Massachusetts Institute of Technology have found a way to filter water using the branches of a sapwood white pine tree. The research showed that the branch from this tree is capable of filtering up to 4 liters of river or lake water a day. It is also ideal for those who are unable to afford other filtering alternatives. This method can clean up to 99 percent of E. coli bacteria, however there's still a little drawback; the branch is unable to filter viruses and other potentially harmful material smaller than 20 nanometers.
