    LifeStraw® uses advanced hollow fiber technology. This is a highly efficient method of filtration. Hollow fibre membrane requires no chemicals like chlorine or iodine.

    1. Water enters and is forced through narrow fibers under high pressure.
    2. Hollow fibers trap bacteria, protozoa, and other contaminants which are flushed out by backwashing.
    3. Clean water exits through tiny pores in the walls of the hollow fibers.
    4. Filtered water is safe to drink.

    Easy to Use

    Anyone who can use a drinking straw can use a LifeStraw®. Simply draw the unfiltered water through the LifeStraw®, blow air back through the straw to flush and clear it after drinking.
