Steripen - Freedom


The lightest and smallest water purifier from SteriPEN, the Freedom features an integrated rechargeable battery so you don't have to hassle with swapping batteries before a big adventure.

  • Compact purifier itself weighs only 2.6 oz. and measures 5.1 x 1.25 x 0.8 in.; carried with the included USB cable, AC adapter (USA adapter) and neoprene case, the total weight is 6.4 oz.
  • Simple to use, the SteriPEN Freedom detects when the device is in water and automatically activates the UV lamp to begin purifying—no buttons to press!
  • Freedom is configured to treat 0.5 liter of water in 48 sec.; a green indicator light lets you know when the treatment is complete and the water is safe to drink
  • To purify 1 liter of water, simply treat the water twice
  • Integrated rechargeable battery is recharged by plugging the device into a computer, AC outlet or solar charger (sold separately) with the included USB cable
  • Includes an LED flashlight that's handy when the sun goes down; activate the flashlight by holding the Freedom horizontal and rotating your wrist 180° 3 times
  • Freedom requires no pumping, chemicals, test strips, extended timekeeping or filters; leaves no aftertaste, will not clog and does not require lubrication
  • SteriPEN system uses UV light rays instead of chemicals to purify water for drinking
  • Ultraviolet (UV-C) light rays safely sterilize clear water by destroying 99.99% of protozoa (including Giardia and Cryptosporidia ), bacteria and even viruses
  • Long used by municipal water districts and bottling companies, low-level UV-C light treats water safely; unit's light will not damage eyes or skin when used properly
  • SteriPEN protects you from risks that cause botulism, cholera, dysentery and typhoid, just to name a few
  • Small size fits most containers—use it in cups, mugs, water bottles and canteens; carries easily in a shirt pocket
  • SteriPEN Freedom turns itself off once ultraviolet treatment is complete; light source can be used up to 8,000 times!
  • Use only on clear water, as cloudy, sediment-laden water hinders effectiveness; FitsAll prefilter (sold separately) clears particulates and debris from water
  • SteriPEN Freedom water purifier includes a USB cable, AC adapter (USA adapter) and neoprene carrying case
