SteriPEN Ultra: The World’s Most Advanced Portable UV Water Purifier Mike Richard August 30 First Look, Gear, Health, Modern Vagabond SteriPEN first popped onto our radar back in 2007. Since then, we’ve been traveling with ours to any destination where tap water might be a bit suspect. Every other year or so, the company manages to make their already ultra-compact, user-friendly water purifiers even better. Their latest version – the SteriPEN Ultra – is billed as “the most advanced UV water purifier in the world”. Features include: a user-friendly, high-contrast OLED screen that provides performance and treatment data; the ability to treat 1L of water in just 90 seconds or 0.5L in 48 seconds; and the impact-resistant bulb is good for at least 8,000 treatments. Bonus: travelers will love the unit’s ability to charge via USB, wall outlet or portable solar panel. Pricing + Availability Available now for less than $100 USD directly from SteriPEN or Amazon.com (aff). Disclosure: Vagabondish was provided one complimentary SteriPEN Ultra unit in advance of this review. Read our view on sponsored content.
