As a result, SteriPEN has earned the Water Quality Association’s Gold Seal, certifying that SteriPEN purifies water safely and effectively. SteriPEN purifies 16oz. (0.5L) in just 48 seconds; 32oz. (1.0L) in just 90 seconds. All without any pumping, timekeeping, or any added aftertaste or chemical odor.
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 Seattle, New York (scheduled soon), Tempe, AZ and many others in North America, Europe and Asia. Ultra Violet light is also used by leading bottled water manufacturers to purify their source water.
The EPA officially recognized the use of ultra-violet as a proven, viable technology in 1996: “Ultraviolet (UV) radiation has been found to be an effective disinfectant…. a useful small systems disinfection technology option.” UV purification works as the ultraviolet energy emitted by the light is absorbed by the cells of the microbe, preventing cell enzymes from ‘reading’ its DNA. Without intact DNA, microbes can’t reproduce to make you sick. The process is simple but effective, destroying over 99.9 percent of harmful microorganisms.
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.
