So you are lost in a far off county. Somewhere is Mexico and you are thirsty. STOP!!! don't drink that water. Use your handy SteriPen to purify the water. I wounder if this can work with any water???
Amazing, amazing product. Traveling down south is not the best way to go right now but if say, you were to go somewhere else and you worry about the cleanliness of water, a SteriPEN is the way to go.
