The Outback™ Water Purification System for Emergency Preparedness, Survival, Camping, Food Storage Programs, and Disaster Relief


Natural disasters can happen anywhere, anytime. Be it from flooding, hurricanes, tornadoes, earthquakes, national emergencies, or manmade disasters; our city water systems or private wells can be compromised. Flooding often fouls municipal water systems. Earthquakes break pipes and infrastructure causing water contamination. Power outages from storms or summer heat leaves people without the electricity required to move water to their taps.

Pipes and infrastructure carrying our water can be disrupted and contaminated with chemicals and microorganisms such as bacteria and viruses. On top of having a bad odor and taste, contaminated water can cause diseases such as dysentery, typhoid, hepatitis and more. All water of an uncertain source or quality should be treated before using for drinking, food preparation, or hygiene.

During and after natural disasters and emergencies, a person can only go a few days without clean, safe water. It is always wise to have an alternative source of safe drinking water - an emergency water purification system. Affordable, cost-effective, and easy to use, The Outback is the perfect emergency water source for you and your family.

Water Filtration for Emergencies

Outback gravity water filter for disaster preparing

The Outback is a gravity-powered water filtration system that purifies water from almost any fresh or moving* water source. Both rugged and durable, The Outback is portable and easy to store, transport and set up.

The Outback’s design has been proven effective by rescue, relief, and religious organizations in Latin America, Africa, the Middle East, and Asia. It is currently used by organizations such as The U.S. Government, the American Red Cross, Youth Mission, the Boy Scouts of America, Samaritan’s Purse, the Church of Jesus Christ of Latter-day Saints, NW HardRain Expeditions, a multitude of local fire departments, and is widely used by missionary and government organizations throughout the world.

FEMA, the American Red Cross, and other agencies recommend an emergency water supply of at least 1 gallon of potable water per person per day. Most purification systems produce only enough water for an individual, while The Outback will easily purify water for an entire family for the duration of an emergency.

In addition to its invaluable use during emergencies, The Outback is recognized as the most crucially important component of any well-planned Emergency Preparedness Kit or a Food Storage Kit as it allows a family of 4 to easily have enough drinking water. 

To use, simply pour water into the upper chamber through The Outback’s pre-filter net to remove large particles of sediment and debris. The various Outback systems can deliver 6 to 48 gallons of purified water per day, depending on on the system type and source water conditions. Check out this Outback Comparison Chart to understand the differences in Outback models.

How the Outback Survival Water Filter Works


Outback portable water purification bucket system eliminates harmful bacteria and viruses, including E.coli, Cholera, Hepatitis and Polio. The official product name is the "OB-25-NF" and the "NF" system indicates the use of a "Nano" pre-filter, which goes farther by removing viruses - achieving greater than 4 log (99.99%) virus reduction rate.

To begin filtering water, simply pour raw or questionable water through the Pre-Filter net and into the upper pail. 

Stage 1:  Pre-Filter net removes debris and large sediment particles.

Stage 2:  The Pre-Filter sleeve removes contaminants down to 5 microns in size.

Stage 3:  In the OB-NF, the finer filtration of the electrostatic Nano Pre-Filter removes microbial contaminants such as bacteria and cysts and viruses. 

Stage 4:  A Multimedia cartridge removes many industrial and agricultural contaminants as well as chlorine, iodine, bad tastes, and odors.
