The LifeSaver bottle is remarkable but it seems like the filtering process doesn't scale well. Imagine having to use this throughout the day each time you fill up.
My company works w/ a charity in rural India that makes BioSand filters. The filters allow people to clean large amounts of water and then save it in containers for later. 90-95% of the impurities are removed. More info here if curious: http://faucetface.com/pages/1-for-100
