Miles Maiden, founder of Hydro-Photon (SteriPEN) loves the outdoor life. One day he thought there should be other ways to purify water than to filter or use chemicals. This became the start of SteriPEN, a pocket-sized purification system that uses ultraviolet light for water purification, destroys more than 99.9 percent of all bacteria, viruses and protozoans. Over the years, SteriPEN has developed 8 different patents and has been awarded several times.
