Do you know in which countries you can drink tap water? If you are on the territory of Russia or Ukraine, drinking tap water is undesirable, but not fatal. If, for example, you are in Italy or Switzerland, you can safely open the taps and drink: the water there is clean and even delicious. In India, it is not even recommended to rinse your mouth with tap water, and people with a weak stomach (and just those who want to be safe) prefer to rinse their mouth with bottled water. That is, clean drinking water in most countries is available only in stores or home filters. And what if you are in a place where there are no sources of clean drinking water? Drinking dirty so as not to die of thirst, as it was after the tsunami in Asia in 2004? Or fight for water, as after Hurricane Katrina (clean water was delivered to the victims for five days!)?
This problem did not allow Michael Pritchard to sleep peacefully, and he decided to create his own filter that would allow cleaning the water from the smallest bacteria and could be almost always at hand. This is how the Lifesaver bottle appeared, which can purify 6,000 liters, after which you need to change the filter.
