 - Small About the size of an electric toothbrush
 - Light Weight  ¹/₂ the weight of other pumps & filter purifiers.
 - Safe  Meets all EPA protocols for microbiological water purifiers
 - Easy to Use  Push Button operation (No pumping. No chemicals.)
 - Freeze-Proof  Use in the summer or in sub-zero weather
 - Effective  Destroys Viruses, Bacteria, Protozoa, Giardia, Crypto,  
                 Bird Flu, E. coli, Hepatitis, Botulism, Cholera, Small Pox,
                 Typhois
 

These purifiers were a Time Magazine "Invention of the Year" and is the only purifies that uses Ultra-Violet light to purify 16 oz of water in 48 seconds or 32 oz in 90 seconds.  Using similar UV treatment techniques used in hospitals, the Steri-Pen's ultra-violet light destroys bacteria, viruses, Giardia. 

Simply place the end of the Steri-Pen in your 16 oz Water bottle, the Steri-Pen automatically comes on, and when the light goes off (in about 30 seconds), the water is 100% safe to drink or use around the camp.

Safe, speedy and effective, UV light has been used by water treatment plants and hospitals for over 50 years to eliminate dangerous bacteria, viruses and protozoa without chemicals or boiling. With  the miniaturization of modern microelectronics, this same proven technology is available in a hand-held purifier that’s compatible with most water bottles, and is perfect for travelers in restaurants, hotel rooms or on the road.

Just stir gently for less than one minute and a 16 oz glass of water will be disinfected and ready to drink. (Should not be used on dirty, discolored water.) Weighs less than 8 oz with four AA batteries. Includes carrying pouch with belt loop. 

How it Works
Just stir gently for less than one minute and a 16 or 32 oz container of water will be disinfected and ready to drink. If your water source is discolored or has suspended debris simply use the Steri-Pen 4 micron "pre-filter" (which screws on the mouth of your Nalagene or wide mouth water bottle.

Steri-Pen® meets standard as set forth in the U.S. EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers.

HOW ULTRAVIOLET LIGHT DISINFECTS

Ultraviolet light treatment is a proven and accepted method for disinfecting drinking water. Short wavelength ultraviolet 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 Steri-Pen® produces 90% of its light at the 254.7 nanometers and is, therefore very effective as an anti-microbiological agent. The treatment time is less than one minute per glass of water.

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 the Steri-Pen® provides between 38,000 and 60,000 micro-watt seconds per square centimeter.
