When camping, hiking, backpacking or traveling the SteriPEN Classic 3 is perfect to keep you safely hydrated. Classic 3’s UV light destroys over 99.9% of waterborne microorganisms that cause illness.

With SteriPEN Classic 3, one set of four alkaline batteries will treat 100 half-liters or 50 full liters of water. Or supercharge your SteriPEN with a set of lithium batteries and you’ll treat up to 150 liters! Classic 3’s enhanced LED indicator panel lets you know treatment size and status of batteries and UV lamp.

Classic 3 is sleek and ergonomic with an easy-to-remove twist-off lamp cover. Like all SteriPEN UV water purifiers, Classic 3 is simple to use: remove the lamp cover, press the activation button, submerge in water and stir. In 48 seconds you have ½ liter of safe drinking water or purify a full liter in 90 seconds. Compared to standard chemical treatments that can take up to four hours, that’s safe water fast without adding chemicals that can leave an unpleasant aftertaste.

SteriPEN Classic 3 Features:

  • Ergonomic design with a new easy-to-remove twist-off cap.
  • The first SteriPEN to work effectively with alkaline batteries. Can be powered by alkaline, lithium, or NiMH batteries.
  • Enhanced LEDs indicate treatment size and status of batteries and lamp.
  • Watertight. No more worries about dropping your Classic 3 in a bottle or stream.
  • So easy, just activate, place in water, and stir. LED indicators flash to let you know when water is safe to drink.
