I'm traveling at the moment, and am finding it extremely difficult to find water that doesn't come in plastic containers. Sometimes I have no other choice.

I've heard it stated before that boiling water can remove the microplastics from it - have you heard of this? I'm curious if it's true, or if you know any other strategies for purifying your water, since I know this is a huge source of microplastics and other toxins people absorb on a daily basis.
