What is the safest way to purify water?
"It's a commonly used technique to clean medical instruments" Just wanted to mention that this method also requires pressure and steam. Don't expect medical sterilization just by boiling. Water can't get past 100 Celsius at standard pressure. en.wikipedia.org/wiki/Autoclave
