    How LifeStraw® Family Works

    LifeStraw®Family uses advanced hollow fiber technology. Water is forced through narrow fibers under high pressure. Clean water exits through tiny pores in the walls of the hollow fibers, but bacteria, protozoa, and other contaminants are trapped inside the hollow fibres and are flushed out by backwashing. This is a highly efficient method of filtration.

    1. The feed water bucket (2 litre capacity) is filled with unpurified water.

    2. The 80 micron textile pre-filter (inside the feed water bucket) removes coarser particles and is easy to clean.

    3. Water passes through the metre-long blue PVC hose and gravity creates sufficient pressure on the membrane cartridge in order to reach a high flow rate.

    4. Ultra filtration takes place in the hollow fibre membrane cartridge–a pore size of 20 nanometre retains bacteria, viruses, parasites and fine dirt particles.

    5. The blue tap is turned to release purified water.

    6. Backwashing of the membranes is done by squeezing the red backwash bulb three times with both taps closed and then releasing the dirty water from the red tap. Opening the red tap disposes of the dirt and impurities.

    NOTE: Water from the red tap should never be consumed. 


    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, Pakistan, Peru, Kenya, Indonesia, DR Congo, South Africa, Mexico, and Bangladesh is now available for consumers.
