The Roving Blue O-Pen is an innovative and desirable alternative to the world of chunky and complicated water purifiers, because it's a highly compact, pen-shaped gadget that quickly and easily destroys bacteria, viruses and other unsavory substances in water in order to make it safe to drink.
What makes the O-Pen water purifiers unique is the fact that they don't make use of chemicals or even UV radiation, but instead use ozone to disinfect water. Given how powerful ozone's effects are, this device works brilliantly despite its small stature, weighing in at only 30 grams . The device is available for $199, a competitive price given the balance between efficiency and size.
The O-Pen water purifiers go to show that purification technologies can absolutely look beyond the usual substances, something that yields an added advantage in the form of compactness.
