The Straw That Can Save Lives

Danish water purification company Vestergaard Frandsen’s latest development could very possibly save millions of lives of those who struggle to find and produce clean water.

Their invention is the LifeStraw, a low-tech, low-hassle personal water filter that enables the user to simply stick one end into a water source of questionable cleanliness, such as a river, and suck. Several layers within the straw manage to filter out 99% of bacteria and viruses. Previously, people of areas with little clean water would be forced to boil water to ensure its safety, using up other resources in the process. With this invention, little maintenance would be required, and it could last for a year or two.

In addition to the personal filter, the company has developed a LifeStraw Family, which uses gravity rather than suction to filter water. By hanging this up in their homes and filling it with water, families would be able to open the bottom for clean, safe water.

These products do, however, have their limitations. While 99% of pathogens are removed, the filter is unable to prevent Giardia Lamblia from entering the filtered water, as this particular parasite is too small for the filters. The company is diligently working on a solution to this problem. Another potential problem is availability, since Vestergaard Frandsen is a small, struggling company that cannot quite afford to give out too many handouts.

Hopefully these problems can be overcome, as this product, in its current state, and especially once perfected, has the potential for aiding many who need it most.
