Getting stuck without clean water is not fun. The good news is there are plenty of devices that can turn any body drinkable. Take the QuenchSea for instance: it is a ultralight seawater desalination device that not only turns seawater into fresh water but also removes bacteria, viruses, and parasites.
The device has up to 50 liters capacity and 2-liter per hour desalination capacity.
