Treat the water you drink to avoid cutting your trip short or bringing home more than photos.

The Steripen Classic 3 Handheld Water Purifier with Prefilter Bundle Pack uses shortwave ultraviolet light to disinfect your backcountry drinking water. The Steripen system disrupts the DNA of harmful bacteria, viruses, and protozoa so they won't infect you on your adventure or afterward. The Prefilter screws onto 63mm-thread bottles, creating a tight seal that removes particles and debris from the water.


  • Takes between 45 and 90 seconds to treat a water bottle
  • Each lamp will treat up to 8000 bottles of water
  • Prefilter fits standard 63mm-thread water bottles and uses a 40 x 40 micron screen to remove particulates from the water prior to treatment
  • Requires four AA batteries (not included)
  • Colder temperature will reduce the number of doses per battery (we suggest keeping your batteries warm in cold temperatures to extend their life)
  • Ships with a neoprene carry case and user guide
  • Item #HYD0022
