SteriPen Ultra

SteriPen has expanded its 2013 lineup with the Ultra, which it calls "the most advanced UV water purifier in the world." 

The Ultra features a user-friendly OLED (organic LED) screen that shows a smiley face if an effective dose of UV light is delivered to your drinking water and a frowny face if the dose of UV light is interrupted — no confusion about whether that water is good to go. 

The Ultra's bulb lasts for 8,000 treatments and is designed with a tapered end to fit a wide variety of containers, including commercial water bottles. Its USB-rechargeable internal battery can be recharged via computer, outlet, or portable solar panel.

SteriPen's Kayla Moore demonstrated the Ultra for us at Outdoor Retailer Winter Market in January. 

SteriPen Freedom

SteriPen also has updated its 2013 Freedom UV water purifier to include a solar panel with a built-in lithium-ion battery. Cloudy skies? Even without sunlight, the battery can charge the Freedom from a computer or outlet through a micro USB port. 

The Freedom is buttonless, with instant-on water detection. It's SteriPen's (and the world’s) smallest, lightest UV water purifier. Designed for a wide range of traveling adventures, and SteriPen bills it as "sleek enough for a restaurant, rugged enough for Everest!"
