Show Description

This handheld water purifier allows you to produce drinkable water from a tap, community well, or any freshwater stream or lake. It adds the convenience of being able to recharge it from a wall outlet, your car, your computer, or from a compatible solar panel.

  • Immerse the lamp and stir. Shortwave ultraviolet light disrupts the DNA of bacteria, viruses, and protozoa, rendering them harmless. Green indicator light lets you know when it’s safe to drink the water.
  • Treats 500ml at a time. Disinfect twice for 1L volume.
  • Up to 40 treatments per charge.
  • Battery and UV lamp life is about 8,000 treatments (500ml each).
  • Includes a neoprene carrying case and AC adapter (100 to 240V, USA prongs).
  • Includes USB cable compatible with computers (micro USB B port), some auto adapters and some solar chargers.
  • LEDs function as small light for finding your way in unfamiliar surroundings.
  • Note: UV devices are intended for treating clear water. They have been shown to reduce microbial contamination in mildly turbid water. If you are treating highly turbid water, follow all package instruction carefully and consider pre-filtering the water.
