No after-taste. LifeStraw has no after-taste, since no chlorine, iodine or other chemicals are used.
No waiting time. You can drink from your LifeStraw right away. There is no need to wait for water to drip or chemicals to act.
5-year shelf life: Can be stored and used periodically. The shelf life is not reduced if the LifeStraw is used occasionally and then put back in storage.
LifeStraw meets or exceeds EPA standards for efficacy. LifeStraw was successfully assessed in laboratory conditions (harsher conditions than what is required by the EPA in terms of turbidity and organic matter), up to 1600 liters (approximately 160% of design life). Independent testing at the University of Arizona showed that LifeStraw exceeds the EPA requirements of LOG 6 reduction for bacteria and LOG 3 reduction for protozoan parasites.
