What is the total number of liters that is recommended can be filtered?
The LifeSaver Cube is designed to be portable and robust. The water is forced through the 15-nanometer filter via pressurization produced with a built-in hand pump in the cap. The activated carbon filter for chemical residuals is designed to filter 100 liters and will last 1 month. According to the instruction manual, the membrane cartridge has FailsafeTM technology that prevents any water from passing through the filter once it has reached the end of its service life.

All parts are replaceable with a maximum membrane cartridge lifespan of 5,000 liters or 4.5 years for a family of 5 filtering 3 L of water per day. At the end of the life of the membrane cartridge, no water will flow and a replacement cartridge is required. The LifeSaver Cube includes a 2-year international warranty.
The Cube was evaluated by BCS laboratories for virus, bacteria, and cyst reduction. Oxfam field tested the Cube and reported on logistics of distribution, ease of use, and design drawbacks as experienced in South Sudan.
No specific known safety risks. Potencial hazards include the consumption of unsafe water that can lead to gastrointestinal problems due failure to follow use and maintenance instructions of the user manual.
Also a pre-filter is recommended for turbid water, as increasing turbidity lowers the flow rate of the Cube to 0.5 L/min and lower at greater than 5 NTU. Safe water storage container for treated water and optional activated carbon filter to remove chlorine, taste and odor.
