Q1. What is LifeStraw? LifeStraw is a portable water purification tool that cleanses surface water and makes it safe for human consumption. It is just 25 cm long and 29 mm in diameter and can be hung around the neck. LifeStraw requires no electrical power or spare parts.

Q2. What does LifeStraw do? LifeStraw filters up to 700 litres of water and effectively removes most of the micro organisms responsible for causing waterborne diseases.

Q3. Which diseases will LifeStraw prevent? LifeStraw kills disease causing micro organisms which spread diarrhoea, dysentery, typhoid, and Cholera.

Q4. Which disease-causing micro organisms are filtered by LifeStraw? LifeStraw filters bacteria such as Shigella, Salmonella, Enterrococus, Staphylococcus Aureus and E.Coli


Q5. Are there any tests to prove this? LifeStraw has been tested by independent and qualified research laboratories.

Q6. How does LifeStraw function? LifeStraw contains PuroTech Disinfecting Resin (PDR) - a patented, extraordinarily effective material that kills bacteria on contact. Textile pre-filters are used in the LifeStraw to remove particles up to 15 microns. Active carbon withholds particles such as parasites.

Q7. What do the tests and research studies indicate? The studies indicate the following:

The level of bacteria in the water will be reduced to levels that will provide water safe for human consumption. ‘Safe’ implies water from which any health risk is minimal. The particulate removal suggests that the number of any parasitic ova in raw water will also be reduced significantly. The released amount of iodine in water treated from LifeStraw is not normally damaging to human health. However, people having thyroid problems and allergic reaction to iodine must seek medical advice before using this tool.

Q8. What is the life expectancy of the LifeStraw? One year from the start of usage (calculation based on consumption of 2 litre water per day) or 700 liters. Use beyond expiry will not deteriorate existing water quality.


Q9. What is the required daily water consumption? The WHO default levels for the quantities of drinking water (reference to WHO drinking water quality guidelines Third edition 2004, Annex III), are: For a 10 kg child, 1 litre water per day - thus 700 days tool For a 60 kg adult, 2 litre water per day - thus a 350 days tool

Q10. Who can use the LifeStraw? Adults and children of any age can use the LifeStraw, provided they have capacity to suck water

Q11. How should LifeStraw be used the first time? First time users are advised to spit out the first couple of mouthfuls (40 ml) as a small amount of harmless black carbon water will be expelled on initial use. First time users may find it difficult to start sucking. This is because a natural brake on the flow of water has been put into the LifeStraw, as a controlled flow between 100 ml to 150 ml per minute is needed to get the maximum benefit of the bacteria killing effect.

Q12. How can LifeStraw be effectively utilised? At regular intervals, it is recommended to blow out the last mouthful of water as well as some air through the LifeStraw. This will clean the pre-filters of whatever sand, silt and debris that might have got stuck in the textile filters.

Q13. Does LifeStraw filter arsenic, iron, fluoride and other heavy metals? No. Q14. What is the impact of saline water on the lifetime of LifeStraw? It is expected that continuously drinking saline water through the LifeStraw would reduce effective life to 350 litres.

Q15. Can I share my LifeStraw with other people? It is not recommended that you share your LifeStraw with others. Any outside contamination of the LifeStraw will not be compensated by inside purification.

That is so freaking cool! I want one...but where would I use it

[aera]

i can't view the links. but seems pretty cool.

[parallel]

Hmm. Weird. But cool.

[Saeglopur]

That's awesome! The world's finally making progress.

[yellowgurl]

That seems cool but how much would it cost? I mean if those people who actually need it cant afford it then wouldnt that be just another invention.

[almondroca_loca]

wow that seen that anywhere before
but that's so coool

[latinprep12]

they seem really cool...i wonder how much and well i would like one, but i doubt i will use it daily or weekly...amy-be when something like war of the worlds happens

[ANG33ZY]

the links don't work for me. but from what i read. I, would, like, a, lifestraw.

[Saeglopur]

Guys ... I know it's like interesting that you want it and all ... but think about how some people don't have any purified water - dirty water like from the river and animals take dumps or pee. Yeah, something to think about.

that's what i was thinking....

the lifestraw was made for people in places like Africa that DON'T have a supply of clean drinking water. some people are so poor that they are forced to drink dirty water just to keep themselves from getting dehydrated.

wow, this is a great invention. i hope that it is put to good use.

[*incoherent*]

owhhhhhhhh ahhhhhhhhhhhh....

i want one now.

ah, modern day technology

[racoons > you]

it is a great invention, bu tlike yellowgirl said, its worthless fo rplaces such as africa, if it isnt affordable, which i cant imagin eit would be

[Aestuarium]

that's great
I don't need it though
