How LifeStraw Mission Works:

LifeStraw Mission uses a highly efficient method of purification that requires no chemicals, batteries or moving parts. Water poured into the purifier moves down the tube, while being forced through narrow hollow fibers. Clean water exits through tiny pores in the walls of the hollow fibers, but bacteria, viruses, protozoa and other contaminants are trapped inside and are flushed out by backwashing.

• Easy-to-remove, 80-micron pre-filter inside bag; also includes extra pre-filter screens
• Purifier is easy to clean in the field, thanks to integrated back-flush bulb
• All raw materials are US FDA compliant or equivalent
• Water passes through the meter-long blue PVC hose and gravity creates sufficient pressure on the membrane cartridge in order to reach a high flow rate.
• Ultra filtration takes place in the hollow fiber membrane cartridge - a pore size of 20 nanometers (0.02 microns) retains bacteria, viruses, parasites and fine dirt particles.
• The blue tap is turned to release purified water.
• Backwash the membrane by squeezing the red backwash bulb 3 times with both taps closed and then releasing the dirty water from the red tap. Water from the red tap should never be consumed.

For every LifeStraw® water filter sold, we provide a child in Africa with clean water for an entire school year.

When you purchase any type of LifeStraw® filter, we use part of the funds to donate LifeStraw® Community institutional water purifiers to schools in Africa. LifeStraw® Community is specifically designed to deliver clean, safe water to school children by removing waterborne pathogens and dirt commonly found in source water.

Since 2014, we provided 316,000 school children or 631 schools in rural Kenya with safe, clean drinking water, thanks to sales of LifeStraw in North America. Thank you for supporting this mission!

The Science Behind LifeStraw:

Backed by serious research in our international labs and extensive testing in the field, LifeStraw and LifeStraw Family have been distributed to nearly every major international humanitarian disaster since 2005 and in broad public health campaigns in the millions.

The same high-tech design used in places like Haiti, Indonesia, South Africa, Kenya, Democratic Republic of the Congo, Pakistan and Bangladesh is now available in the USA and Canada.
