This interesting piece of modern technology, named SteriPEN, is made especially for that purpose - to eliminate any bacteria and viruses that can live in water. It makes this work using UV rays, which are proven to be deadly for those microscopic enemies. SteriPEN is very easy to use - turn it on, take off the lid and place one end into a glass of water. After short time, all viruses should be eliminated for sure. Water is safe for drinking and you have no need to carry your kettle around.
