We all like to draw our water from nature when camping or hiking, but even a stream that looks clean may not be. Microorganisms most often come from animal and human waste and are spread by water run-off. Since we can’t visually detect contaminated water, it’s best to protect yourself with a water purifier. Thousands of outdoor enthusiasts all over the world have trusted SteriPEN for many years. Introduced to hikers and campers at REI in 1999, TIME Magazine named the SteriPEN one of the “Best Inventions of the Year” in 2001.
