Globally, water supplies are increasingly threatened by pollution and contamination. In 1999, Miles Maiden received the first of several patents in pursuit of a user-friendly solution to this problem. Built around the motto "safe drinking water anywhere", the revolutionary SteriPEN is the first personal, portable device to employ germicidal ultraviolet (UV) light to break down the DNA of bacteria, viruses and cysts, including Giardia and Cryptosporidium, rendering them harmless and making water safe to drink. Fast and effective, the SteriPEN is an ideal choice for hikers, international travelers, relief workers and anyone preparing for emergency situations.
