SteriPEN products use ultraviolet (UV) light technology to purify water, destroying more than 99.9 percent of bacteria, viruses and protozoan cysts such as giardia and cryptosporidia.
The method has now been used for over one hundred years, and is currently used to purify drinking water by some of the largest cities in the world, including in North America, Europe and Asia. Ultra Violet light is also used by leading bottled water manufacturers to purify their source water. Purifying water with UV light offers many advantages. In addition to being safe and effective, UV light does not alter the taste, pH, or other properties of the water, and works without the introduction of chemicals to the water. Use shortwave ultraviolet light to disinfect your water. When you immerse the lamp in the water it disrupts the DNA of bacteria, viruses and protozoa, rendering them harmless. Use a pre-filter to clear particulates and debris before you purify the water.
