SteriPen Water Bottle Pre-Filter
About SteriPen Ultraviolet (UV) Water Treatment:
The ultraviolet (UV) water treatment 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 North America, Europe, and Asia, including Seattle, Washington and Tempe, Arizona. Ultra violet light is also used by bottled water manufacturers to purify their source water.
The EPA officially recognized the use of UV water treatment as a proven, viable technology in 1996. In a simple but effective process, UV purification destroys over 99.9 percent of harmful microorganisms in drinking water. The UV energy emitted by the light is absorbed by the cells within potentially harmful microbes. The UV energy breaks down the cells' ability to reproduce DNA--making it impossible for them to reproduce and make you sick.
