New LifeStraw Mission is the First Gravity Powered Water Purifier to Remove Bacteria, Protozoa and Viruses from Backcountry Water

Lausanne, May 18 -- LifeStraw® Mission is a high-volume gravity powered water purifier that removes viruses in addition to bacteria and protozoa to make backcountry water safe to drink. The compact, lightweight water purifier incorporates award-winning Lifestraw® technology to transform microbiologically contaminated water into safe water. It is easy to use and maintain, making it ideal for group camping trips, group hikes and expeditions. Backcountry water purified by LifeStraw® Mission can be saved in a canteen or bottle for drinking or used for cooking and other campsite activities. 

The durable water purifier removes 99.999% of viruses including Rotavirus and Hepatitis A. Additionally LifeStraw® Mission removes 99.9999% of bacteria (E.coli, etc.) and 99.99% of protozoa (Giardia, Cryptosporidium) and it reduces turbidity (muddiness) up to 0.02 microns. With this comprehensive level of purification, LifeStraw® Mission eliminates the need for iodine or chlorine tablets to purify water and provides the additional protection of virus removal.

LifeStraw® Mission is made of a durable waterproof nylon roll bag with an integrated ultrafiltration membrane purifier. It meets the highest quality standards set by the US Environmental Protection Agency and World Health Organization, and will purify up to 18,000 liters or 4,755 gallons of water throughout its long lifetime.

Consumers can choose from a 5-liter (1.3 gallon) capacity LifeStraw® Mission purifier or a 12-liter (3.2 gallon) capacity version. With a dry weight of 13 and 15 ounces (5 and 12 liter size, respectively), these purifiers can be rolled up for easy storage in any type of backpack. 

LifeStraw® Mission is easy to use and maintain. Users simply fill the roll bag with the cleanest water available. Then they fold the top to seal it, clip the strap around a sturdy tree branch, connect the hose to the bag and allow a few minutes for clean water to start flowing from the safe water outlet.

Lifestraw® Mission uses a highly efficient method of purification that requires no chemicals, batteries or moving parts. Water poured into the roll bag moves down the tube, and into the narrow hollow fibers of the ultrafiltration membrane. Clean water exits through tiny pores in the walls of the hollow fibers, but bacteria, viruses, protozoa and other contaminants like dirt particles are trapped inside and are flushed out by backwashing.

This purifier joins all other LifeStraw® consumer products that support the LifeStraw® Follow the Liters program. Under this ongoing initiative, for each consumer purchase of a LifeStraw® product, one school child in a developing country receives safe water for an entire school year. With this ongoing commitment, consumer purchases continually support the mission of LifeStraw® --- to improve the lives of people without access to safe water.

LifeStraw® Mission is being offered in North America exclusively through leading outdoor retailer REI until July 1. The suggested retail price is $119.95 for the 5-liter version and $129.95 for the 12-liter version. In Europe, the suggested retail price for LifeStraw® Mission is 119.95 Euro for the 5-liter version and 129.95 Euro for the 12-liter version, including sales tax and VAT. For more information visit
