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. Our review will look at three of the best self-filtering water bottles which are suitable for air travel and highlight both positive and negative features, ensuring you choose the best water bottle for you.

LifeStraw Go Water Filter Bottle

The LifeStraw Go Water Filter Bottle has a capacity of up to 22 fluid ounces. There are no size variations, but for those of you who like to fly with everything color coordinated, including your self-filtering water bottle, there are up to ten different color options. There is one option which has two bottles instead of one, if you don’t mind one blue and one purple bottle.
