Seattle-based Mountain Safety Research, a developer of essential gear for challenging environments, introduces the MSR® MIOX® Purifier. Easy to use and reliable, this lightweight, handheld device is about the size of a magic marker and uses electricity to convert salt and water into a powerful disinfectant. Its small size and capacity to treat up to a gallon of water with a single dose makes it ideal for outdoor groups, adventure travelers, military troops or any situation requiring large amounts of pure water.
