The Lifesaver Jerrycan is capable of holding up to 18.5 liters of water at a time, and can produce up to 10,000 liters of water through the life of the device. The Jerrycan uses an activated carbon filter that reduces a broad spectrum of chemical residues and contaminates; a single filter lasts for 500 liters. Lifesaver’s own FAILSAFE technology deliberately increases the number of pumps required to induce water flow as the device reaches the end of its filtration capacity, and makes it impossible to flow water when the cartridge needs replacing. The Jerrycan also features a flow rate of 3 liters per minute and can be used with an optional shower attachment which plugs on and off in seconds. A 20,000 liter variant is also available.
