This version is a type of straw that uses the same charcoal method as the space filter.You can use them to filter stagnant water. There are some of these filter that you can buy that are very powerful. It is so powerful that it can turn soda into water. It is helthier for people that don't have much clean water to use this device to filter the very little dirty water that they have. That how we use it.
