Straw of Life

Being an avid traveller, having a good supply of clean water is vital. The £19.99 iStraw seems to be a good candidate as portable water filter.

While the LifeStraw® worth £1.85 a straw, the prototype design still can’t filters 5 micron spores like Giardia and Cryptosporidium, which can cause diarrhoea and upset tummies. Giardia lamblia itself is an organism that is resistant to iodine. High content of iodine level might be another drawback for the LifeStraw® option.

Enterococcus faecalis, Escherichia coli B, Vibrio cholerae, Campylobacter, Klebsiella and Salmonella bacteria can be removed with the efficiency of 99.99999% for every 700 litres of water for LifeStraw® and 500 litres of water for iStraw.

LifeStraw® the TIME’s “Best Inventions 2005” might be good enough for the inhabitants of the third world countries; the “upmarket” iStraw however would be a better choice for the world travellers.
