What is the Lifestraw ?
Sometimes, technology and innovation are here to save the day.
A brand new portable water filter called LifeStraw will let users drink water from almost any imaginable source. Whether it’s water from a stream or contaminated dam, the LifeStraw will purify it, removing both dirt and pathogens.
Instead of having an expensive filtration system that requires electricity, the designers of the LifeStraw used passive filtration technologies (iodine and coal for the lifestraw).
The simple act of sucking on the straw, which measures 29mm in diameter and is just 25cm long, sets into action the filters and purifies the water.
Vestergaard Frandsen, the Swiss company who created the straw, shows that it has positive results on regular tap water as well as dirty water from swamps and dams, to even saline water. In all cases the LifeStraw has been able to eliminate waterborne bacteria such as Salmonella, Shigella, Enterococcus and Staphylococci.
How long can I use it ?
Powered by humans, the device can filter up to 700 litres of water. That’s enough to get one person water for about a year. To clean it after use, you just need to blow on it, to clear out the filters.
These filters will take care of anything up to 0.2 microns in size – less than a quarter the size of a red blood cell.
Contribute to help Africa
One LifeStraw does attract a price that is affordable. At $20 it is by no means prohibitively expensive, but charities should rally up sponsors to get these into the hands of villagers in developing countries around the world.
And Vestergaard has an even better policy: for every LifeStraw purchased, it will donate clean drinking water to school children in Africa. The more you drink, the more they get to drink, too.
