Turns your water crystal clear

Until we met the LifeStraw, us here folks at Vat19 were unfamiliar with the term "turbidity". Now we know that it refers to the cloudiness of a fluid caused by suspended solids (aka funk).

The LifeStraw, in addition to ridding the life-threatening diseases that may be present in natural water sources, also turns cloudy water crystal clear.

The LifeStraw remarkably reduces the turbidity of water.

Originally developed as an emergency relief aid

The LifeStraw is a world-changing invention that was initially designed to provide life-sustaining aid during natural disasters. It is also being used in many developing countries where access to sanitary water is limited.

Your purchase of a LifeStraw guarantees that a child in a developing country has access to clean water for an entire school year.

With every purchase of a LifeStraw, the manufacturer donates a unit to a child in need for an entire school year.
