Camelback have recently released a new reusable water bottle that has a built-in purification! I think this is the first of its kind. Bobble make a water bottle with a built-in filter, but not purifier. It’s only available in the US at the moment. It’ll be great to see some reviews on this water bottle. Definitely great for adventure travellers!
If anyone has any information on this water bottle, please post a comment! I read it’s no good with boiling water.
