What you get Ultraviolet light neutralizes waterborne germs with this SteriPEN highlighter-size stick. It’s USB-rechargeable and one charge will treat about 50 liters at 90 seconds per liter. And unlike most filters (including the Sawyer MINI), it zaps viruses as well as bacteria and protozoa. The UV lamp lasts for around 8,000 treatments.
Trail cred “Hands down the best water treatment option for world travelers,” Kwak-Hefferan says. “Way lighter and less bulky than filters that eliminate viruses, no chemical taste, and it’s idiot-proof—a smiley face lets you know you’ve done it right.”
