Steripen Opti UV Water Purifier


Compact and lightweight, the Katadyn Steripen Adventurer Opti UV Water Purifier uses an optical sensor to detect water and works in even the coldest conditions.


  • Easy to use: Simply click the button to activate, place in water and stir; when water is purified, the UV lamp turns off and an indicator signals
  • Ultraviolet UV-C light rays safely sterilize clear water by destroying 99.99% of protozoa, including giardia, cryptosporidia, bacteria and even viruses
  • UV-C purification of clear water helps protect you from risks that cause botulism, cholera, dysentery, typhoid and more
  • Optical sensor doubles as a convenient LED flashlight
  • Retail package includes 2 non-rechargeable (disposable) CR123 batteries, a neoprene case with belt loop, and user instructions
  • Device works with containers with minimum 1.75 in. diameter opening (i.e. Nalgene wide-mouth bottles)
  • One set of CR123 batteries will treat up to 50 liters of water
  • UV lamp life: 8,000 treatments
  • Small and lightweight, weighing just 3.8 oz. with batteries
