Here Is Why The Charcoal Water Filter Will Change Your Life

 · Carbon filtering is a method of water filtration that uses activated carbon to remove impurities and contaminants from water. The active charcoal stick responsible for this is called binchotan charcoal and it comes from tree branches. Once activated it works by absorbing impurities like chlorine by attracting the negative ions to its surface.
