Outback Plus OB-25NF

The Outback Plus OB-25NF is an upgraded gravity-powered system that purifies almost any fresh or moving water source that provides finer filtration over ordinary Outback systems. It is designed to be for emergency and disaster preparedness, for daily use when municipal water systems are compromised, or in undeveloped area where treated water isn't available like during camping. The OB-25NF has four stages designed to eliminate virtually all bacteria, cysts, organic contaminates, chlorine, and because of the finer filtration, viruses that may be lurking in the water. The Outback Plus OB-25NF allows for between 6-12 gallons of purified water per day. Discover more about the Outback system.
