Steripen AdventurerOpti - Filters & Purifiers: Reviews

Portable Purification

We've been big fans of Steripen's UV-light wands for years. You just swish it around in your one-liter bottle for 90 seconds and it zaps everything from viruses like hepatitis to protozoa like giardia. This newest version is smaller, has a new optical water sensor that can sense when the purifier is in water, and also has a small flashlight. steripen.com
