LifeStraw® - FAQ
 |
What is LifeStraw®?
|
|
| LifeStraw® is a portable water purifier that effectively removes all bacteria and viruses responsible for causing common diarrhoeal diseases. LifeStraw® requires no electrical power or spare parts and can be carried around for easy access to safe and clean water. |
|
 |
What is the need for LifeStraw®? |
|
A significant amount of daily water consumption, especially amongst kids, takes place outside the home-walking long distances to and from school, kids often find it difficult to obtain potable drinking water. LifeStraw® has, therefore, been developed to provide an accessible, effective solution to the 'instant' need for safe water intervention. |
|
 |
Who can use LifeStraw®? |
|
Since humans have the natural ability to suck, both adults and children above three years can use LifeStraw®. |
|
 |
How is LifeStraw® used? |
|
Simply dip LifeStraw® into a water source and suck on it to draw the purified liquid up. |
|
 |
Which micro-organisms does LifeStraw® filter? |
|
| LifeStraw® effectively removes waterborne bacteria and viruses. |
|
 |
How does LifeStraw® function? |
|
| LifeStraw® contains a specially developed halogenated resin that kills bacteria and viruses on contact; a special chamber further increases the exposure of micro-organisms to the halogenated resin, thereby enhancing the killing effect. Micro-filters are used to remove all particles down to 15 microns. Activated carbon adsorbs residual iodine thereby improving the taste of water. |
|
|
 |
Where has LifeStraw® been tested? |
|
| LifeStraw® has been tested at the University of North Carolina, USA. |
|
 |
What happens if LifeStraw® is used beyond 700 litres or one year?
|
|
| LifeStraw® has been tested for its efficacy beyond 700 litres and it still retains considerable efficacy on bacteria and viruses. However, we do not recommend the use of the product beyond 700 litres. |
|
 |
What is the shelf life of LifeStraw®? |
|
| LifeStraw® can be stored for three years at a maximum temperature of 30 degrees. Storage at a higher temperature will not hamper the working of LifeStraw® but in such a case, the first few millilitres of water consumed will have an initial lower killing effect on the bacteria and viruses. |
|
 |
What must one do if LifeStraw® gets blocked? |
|
At regular intervals, it is recommended to do 'backwashing' that can be done by blowing out some air through the LifeStraw®. This will clean the pre-filters of whatever sand, silt and debris that might have got deposited in the textile filters. |
|
 |
What effect does LifeStraw® have on turbid water? |
|
LifeStraw® does not remove complete turbidity from water; however, it removes the bacteria and viruses as well as undissolved particles down to the finest microns. If you need to consume turbid water, use LifeStraw® to drink only from the surface i.e. the top layer. Excessive intake of turbid water would clog the filters and therefore regular backwashing would be required. |
|
 |
What effect does LifeStraw® have on salt water? Does it make saline water potable? |
|
LifeStraw® does not make saline water potable; however, it still removes the bacteria and viruses from the salty water. |
|
 |
Does LifeStraw® filter heavy metals like arsenic, iron and fluoride? |
|
| No, the present version does not filter any of the heavy metals. |
|
 |
Does LifeStraw® remove parasites like cryptosporidium and giardia? |
|
| No, the present version does not filter any parasites. |
|
 |
Why have Enterrococus faecalis and Escherichia coli been chosen for testing LifeStraw®? |
|
| The test results for Enterococcus faecalis and Escherichia coli B can be extrapolated to other bacteria such as Vibrio cholerae, Campylobacter sp., Klebsiella and Salmonella sp., etc. |
|
 |
