LifeSaver

It removes out 99.99999 % bacteria from all sources of water and also other over 99 % percent of other microbes, and this is all done by LifeSaver, the world’s first all in one ultra filtration water bottle. 750 cc of pure clean water out of LifeSaver is not too much but helps you not to be thirsty while you need clean water in unexpected situations or distant places(though if you find any source of water!). Michael Prichard (again British) video describes his invention and design. He is interested in aid market and he has made a great step toward that, but the price of 230/195 £ is too much expensive for third world countries or charities, since they are target people who are in need of clean cheap water!
