Design Specifications

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.

Replacement Components

Activated carbon filters and membrane filter cartridges are available from the manufacturer.

Lifecycle

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.

Manufacturer Specified Performance Parameters

The filter is designed to filter 5,000 L  under conditions with low turbidity while removing 99.99% of viruses, 99.9999% of bacteria, and 99.9% of cysts.

Vetted Performance Status

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.

Safety

No specific known safety risks. Potential 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.

Complementary Technical Systems

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.

    – The line “It is sold online by LifeSaver and distributed by Oxfam in South Sudan” seems to be one example of where it was implemented, but this shouldn’t appear in the Product Description.
    – Minor, but I would change “Online for USD115” to be consistent with how prices are listed across other porducts

  2. Anna_Advisor says:

    – “End of life indicator (yes/no): Yes. The filter will automatically stop working after 5,000 Liters have been filtered”: I find this hard to believe… how does that happen? Does it measure that volume of water, or does it clog after a long time and then you’re supposed to stop?
