On an extended backpacking adventure or gap year? Chances are, at some point you'll be staying in a dodgy hostel or setting up camp somewhere. And whether the water is coming from a river, standpipe or a shared kitchen, it's best not to take any risks.

Or maybe you are travelling in comfort but heading to a part of the world where the tap water is not as trustworthy as you're used to?

Either way, you don't want to be far from home without a replacement filter. We can send spares almost anywhere in the world but tracking you down could be a challenge! Choose a pack that has everything you could possibly need.
