There are certain time frames that that can be applied to this technique, and it can be modified by using reflective surfaces. the idea is that UV light sterilizes the water. I do not know the details regarding the amount of time etc. that water must be left out if various conditions, but is is a cheep method that could likely be used a lot more. There are also small electric devices that create ozone in water, as well as cheep filters, that can be used on a small scale communal basis. The problem is getting systems implemented and making them self sustainable. t hey menka

Really good point about customers using the LifeStraw after its short lifespan is over... I wonder if the company have a strategy to deal with that issue!? Thanks for your comment.

If they are as effective as you claim, they'll also be very useful in disaster relief situations as a stop-gap measure to combat the spread of disease until cleaner water can be found again. I would have thought that the major problem is in making sure that the straws aren't used beyond 700 litres, or collected and sold as new straws to people when they are past their useful life. Thanks for the site anyway.
