Great find here. It's a very promising portable water purifier. It claims to be able to purify water by removing bacteria, viruses, and protozoa using sun-activated nanotechnology.
It has a 7-year shelf life and can be used for 100 cycles of purification, so you can produce a total of 300 liters of water from a single bag. It's perfect for outdoor adventures, humanitarian projects, and relief operations. And since you're really just carrying plastic a bag, it's also very portable.
