SteriPen Ultralight 3oz UV Water Purifier

The SteriPen Ultralight is the smallest and lightest UV water purifier in the SteriPen lineup, weighing just 3 ounces (76.5g) and designed for ultralight backpackers, travelers, and minimalists who count every gram . The device is water-activated, automatically starting purification on contact with water and shutting off when removed, which prevents accidental battery drain in your pack . Its powerful UV-C lamp destroys 99.9% of bacteria, viruses, and protozoa (including Giardia and Cryptosporidium) in clear water, treating one liter in just 90 seconds without chemicals or altering taste . The integrated USB-rechargeable lithium-ion battery provides approximately 20 treatments per full charge, and the UV lamp has an exceptional lifespan of 8,000 activations . The device is compatible with containers having openings of at least 38mm in diameter and is best suited for clear water sources; highly turbid or sediment-filled water should be pre-filtered to ensure optimal UV effectiveness . The purifier comes complete with a neoprene carry pouch and USB charging cable, making it a reliable, fast, and chemical-free solution for safe hydration on any adventure.
