Whether you need it for practical, everyday purposes or for adventures into the wilderness, the SteriPen is a must have.

At least that’s what G. Mark Johnson recommends in his book, The Ultimate Desert Handbook.

Johnson is an avid hiker. His book is loaded with tips and advice, especially for those who are looking for resourceful ways to improve their skills and trek even deeper into remote areas of the globe.

Here’s Johnson on the SteriPen’s benefits:

Ultraviolet (UV) radiation has been used for years to purify water, but the Steri-Pen is the first truly portable device I know of to use the principle to treat water without chemicals. About 7 inches long and weighing 6 ounces, the Steri-Pen uses four AA batteries to light a germicidal UV lamp ( liquid level sensors prevent the UV lamp from lighting unless it is fully submerged in water). After collecting and straining a pint of clear water, you can activate the Steri-Pen with a button-pushing sequence, and stir the tip of the pen in the water for thirty-eight to forty-eight seconds. A microcomputer determines the exact duration of the UV dosage, and a small LED (light-emitting diode) light indicates when the treatment is complete. That’s all there is to it.

So, before you next venture into the woods or dessert, make sure to have a SteriPen. It’s the mobile device that will clean your water and keep you going longer.
