SteriPEN is located on the coast of Maine in the town of Blue Hill. SteriPEN employees greet each day by arriving to work in a spacious barn. The atmosphere is very relaxed where employees are welcome to grow a vegetable or herb garden. Miles Maiden is Hydro-Photon’s founder and inventor of the SteriPEN™.

SteriPEN is easy to use. SteriPEN™ provides a system pack which includes a SteriPEN, Pre-Filter and 1 Liter BottleSteriPEN™. The Classic UV Light Water Purifier SteriPEN™ is the only portable batch water purifier that uses Ultraviolet (UV) light to destroy waterborne microbes.
