SteriPEN® meets the U.S. EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers. University Testing (University of Arizona, University of Maine & Oregon Health and Sciences University) shows greater than 6-log, 99.9999% reduction of bacteria and greater than 99.99% reduction of viruses.

SteriPEN™ is the only portable water purifier that uses ultraviolet (UV) light to destroy waterborne microbes. Whether your source is a woodland brook or an overseas hotel tap or "purified" resturant table water, SteriPEN sterilizes clear water by destroying viruses, bacteria and protozoa—including Giardia and Cryptosporidium—in seconds. Carry a SteriPEN to disinfect water wherever you travel, hike, camp or trek. It’s the fastest route to pure, safe drinking water anywhere… NO PUMPING… NO CHEMICALS needed… EVER!

Simple & Easy to Use:

• Dip the UV germicidal lamp into the water
  (built-in safety switch prevents light turning on unless in water)
• Fast automatic UV dosage delivered quickly
• Push Start Button Once for 32 oz. (1 liter)treatment
  (32 oz NALGENE® lexan water bottles work excellent for this),
  or Push Twice for 16 oz. (.5 liter) Treatment

Steri-Pen is tested to the EPA protocol for water purifiers. Successfully used by outdoor enthusiasts, expeditions to Everest and Mt. Aconcagua, international travelers, missionaries, and the U.S. Army.

Here's What Customers Have Said:

"During my climb of Kilimanjaro the rest of my party used traditional pumps and filters. Needless to say one by one they all asked to use the SteriPEN™."
—Richard Wiese, President
The Explorers Club, NYC

"It's the perfect mountaineer's companion. Because SteriPEN™ is small and unobtrusive, I found it useful while traveling, not just camping."
—Michelle Gregory, Professor
Brown University Everest Expedition

TIME Magazine calls Steri-Pen one of the "Best Inventions of 2001"

Backpacker Magazine says “I found the Steri-Pen’s speed and efficiency welcome, especially when purifying several bottles at a time. The device is faster than pump filters for large groups (no muscle required) and quicker than chemical treatment even if you’re solo (no waiting).”
-Dennis Lewon, April 2002

And Newsweek Magazine says the cost of Steri-Pen is a "small price to pay to avoid dancing the green-apple two-step."

The New York Times says, "Instead of trusting the water at their destinations, vacationers can zap bacteria with the Steri-Pen..."

To operate, Steri-Pen is activated with a simple button push. Once engaged, the onboard microcomputer determines the proper dose duration. When Steri-Pen's liquid level sensors indicate that the germicidal ultraviolet lamp is fully immersed in the container of water, the microcomputer activates the lamp for the dose period (between 38 and 48 seconds). After less than a minute of gentle stirring the treated water is disinfected and ready to drink. Press the Start button once to treat 32 ounces of water or twice to treat 16 ounces (sounds a little backwards but it's actually a built-in safety so as to never undertreat your water… good thinking!)

HOW ULTRAVIOLET LIGHT DISINFECTS

Ultraviolet light disinfects rapidly without the use of heat or chemicals. Ultraviolet treatment is often used in the final stage treatment of bottled water for added safety. Operating rooms, isolation areas and other medical facilities make extensive use of ultraviolet germicidal lamps to maintain a low bacterial count in the surrounding air.

Ultra-Violet light treatment is a proven and accepted method for disinfecting drinking water. Short wavelength ultra-violet light, commonly referred to as UV-C occurs between the wave length of 200 and 265 nanometers, and this is where the most effective germicidal action occurs. The HYDRO-PHOTO LAMP PRODUCES 90% of its light at the 253.7 nanometers and is, therefore very effective as a anti-microbiological agent.

Microorganisms encompass a wide variety of unique structures and can be grouped into five basic groups: bacteria, virus, fungi, protozoa, and algae. A microorganism is composed of the cell-wall, cytoplasmic membrane and the cell's genetic material, nucleic acid. It is this genetic material or DNA that is affected by the Ultraviolet light. As UV-C penetrates through the cell wall, it causes molecular rearrangement of the microorganism's DNA thus preventing reproduction. If a cell can not reproduce, it is considered to be microbiologically dead. Due to individual cell makeup, different levels of UV energy are required for destruction.

The effectiveness of UV microbial destruction is a product of both time and intensity. The intensity of UV-C light is measured in micro-watts per square centimeter and the time is measured in seconds. Hence the amount of ultraviolet light necessary to kill a particular microorganism is reported in units of micro-watt seconds per square centimeter; this is known as the dose. UV light testing has shown that Steri-Pen provides between 38,000 and 60,000 micro-watt seconds per square centimeter.
