The SteriPEN Emergency is a compact, lightweight device that uses UV light to quickly kill harmful microbes, viruses and bacteria that may be present in water. The Emergency is specifically designed for home emergency and disaster preparation kits. It is designed to fit perfectly into commercial water bottles, forming a seal that lets you keep the water in the original bottle for purification. Just insert the Emergency securely into the mouth of the bottle, turn it upside down, and you have safe drinking water in less than a minute.
