Taking along the best water bottle for air travel will go a long way towards making sure you are hydrated on any flight, short or long haul. Staying hydrated is not the same as ‘drink a lot,’ which can be interpreted in many ways, and one or two of them will not do you much good at all. Traveling with the best self filtering water bottle will filter out virtually all the bacteria and chemicals found in even the cleanest tap water, making it extremely healthy for you to drink en route.
