The LifeStraw personal water filter, the "Best Invention of 2005" (Time magazine), enables users to drink water safely from contaminated water sources. LifeStraw is ideal for homeowners during emergencies such as local flooding which can contaminate drinking water supplies. 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.

Eartheasy is the official wholesale distributor and retail launch partner for LifeStraw, which as of September 2011 is now available for US and Canadian customers to purchase. Since 2005, LifeStraw has been used in developing countries to assist in achieving the United Nations’ Millennium Development Goals for clean drinking water. We’re excited to help launch this useful product in North America.
