The LifeStraw personal water filter, a “Best Invention of the Year” (Time magazine) winner, enables users to drink water safely from contaminated water sources.

LifeStraw is also ideal for campers and hikers who may be drinking from rivers or lakes and are unsure of the water safety. Because LifeStraw is lightweight and compact, it is also great for travelers who do not want to rely on the quality of local water. LifeStraw is the most advanced personal water filter available today. LifeStraw surpasses EPA guidelines for E. coli, Giardia, and Cryptosporidium oocysts, rigorous standards for water filtration.
