  • Ultraviolet (UV-C) light rays safely purify clear water by destroying 99.9% of protozoa (including Giardia and Cryptosporidia), bacteria and even viruses
  • The revolutionary optical water sensor doubles as an integrated LED flashlight. Hold down the activation button for three seconds to illuminate the darkness.
  • When the treatment is complete, LED indicators flash to let you know that the water is safe to drink.
  • Use only on clear water, as cloudy, sediment-laden water hinders effectiveness.
