Product description

Featuring a user-friendly display Ultra is rechargeable via a computer, outlet or portable solar panel. Ultra’s UV lamp treats up to 8,000 one-liter treatments and is proven to be safe and effective, eliminating over 99.9% of bacteria, viruses and protozoa that cause water-borne illness.

  • 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 purify 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

Well designed, decent instructions, just what I need. However, it's not for cloudy water.

Well, we’re in India and have been using this for the last few weeks, just drinking water from anywhere and it’s been great, we haven’t been ill so I guess it’s probably working?! The battery is good, haven’t really had to charge it yet, and it arrived quickly to the Uk. Thankyou!

Easy to use and although the instructions in Finnish were missing, the instruction was quickly used. Small and light carry included.

Very functional. Ten to 2-7 days of hiking, and with this cleaned up all the water used. My friend and I have at least been spared from stomach ailments, although at times the water intake has been more than alarming looking.
