Afterpay – How it works
The SteriPEN® Classic 3 is a versatile, portable UV water purifier that has been used on mountains and trails for over 15 years. It operates on four AA batteries which can be alkaline, lithium or rechargeable NiMH, has a UV lamp that lasts for 8000 activations. The Classic 3 can treat a litre of water in just 90 seconds, killing 99.9% of bacteria, viruses and protozoa that cause water-borne illness and is easy to use with its easy-to-remove twist-off cap. The LED display shows treatment size and status of the batteries and UV lamp and flashes when the treatment is done.
  • Trusted on mountains and trails for over 15 years, the Classic 3 is the best-selling portable UV purifier of all time
  • For use on tap or clear water - use a pre-filter or similar to filter out larger particulates if present
  • Enhanced LED indicator panel lets you know treatment size and status of batteries and UV lamp
  • Sleek and ergonomic with an easy-to-remove twist-off lamp cover
  • Ultraviolet (UV-C) light rays safely purify clear water by destroying 99.9% of protozoa (including Giardia and Cryptosporidia), bacteria and even viruses
  • Treatment time is 48 or 90 seconds (half or full litre) and when the treatment is complete LED indicators flash to let you know that the water is safe to drink
  • Use only on clear water, as cloudy, sediment-laden water hinders effectiveness
  • Designed to treat 500ml to 1 litre of water at a time (if you have more then separate into 1 litre or less amounts)
  • Requires no pumping, chemicals, test strips, extended time-keeping or filters; leaves no after taste, will not clog and does not require lubrication
  • When operating properly the Classic 3 will emit a visible light as well as UV light so if you can't see a light it needs to be repaired before further use
  • Minimum bottle diameter = 22mm
  • The Classic 3 takes 4 x AA batteries - alkaline, lithium or rechargeable NiMH (not included)

  • When not in use, Classic 3 should be kept in a safe place that is clean and dry. It should not be exposed to temperatures above 49°C or below -20°C.
