  • Ultra features an internal battery that's recharged from any USB power source; connect the included USB cable and start charging from a solar panel, laptop or car power port 
  • Low-power indicator lets you know when battery needs recharging; when fully charged you can treat 50L 
  • Ultraviolet (UV-C) light rays safely sterilize clear water by destroying 99.99% of protozoa (including Giardia and Cryptosporidia), bacteria and even viruses 
  • SteriPEN protects you from risks that cause botulism, cholera, dysentery and typhoid, just to name a few 
  • To purify your water, just press a button and gently agitate the water with a quick stir 
  • Purifies 16 fl.oz. of water (cold or warm) in less than a minute or treat 32 fl. oz. in 90 seconds 
  • Ultra is designed to fit perfectly into store-bought bottles of water; just insert the Ultra into the bottle, flip the bottle upside down and start treating the water 
  • Small size fits most containers—use it in cups, mugs, water bottles and canteens 
  • SteriPEN turns itself off once ultraviolet treatment is complete; can be used up to 8,000 times! 
  • Watertight seals keep water away from the electronics; rubberized inset grips for secure handling in wet conditions 
  • Long used by municipal water districts and bottling companies, low-level UV-C light treats water safely, and unit's light will not damage eyes or skin 
  • Use only on clear water, as cloudy, sediment-laden water hinders effectiveness; FitsAll prefilter (sold separately) clears particulates and debris from water 
  • Includes SteriPEN Ultra water purifier, USB cable, carrying case and instruction manuals 
  • SteriPEN Premium Lamp Life Pledge lets you register your purchase to receive a replacement SteriPEN after 8,000 uses; find details at
