I bought this Jerrycan brand-new several years ago and kept it stored on a shelf, never used. Since then, I've never have seen another yellow one like it! (all the LifeSaver Jerrycans seem to be blue).  I'm facing some unexpected bills right now, so the time has come to part with this very unique item. This LifeSaver Jerrycan is perfect for group expeditions, overland travel or for off-grid living, where water portability and purification is crucial. Produce your own clean drinking water for camping, overland travel & off-grid living. This is an extremely rugged and time-proven jerrycan container with high technology filters. What's the point of filtering water if you cannot safely transport it in a rugged environment? This Jerrycan solves both problems - purification and portability. This Jerrycan has a robust water filter capable of delivering up to 15,000 liters of clean water. The LIFESAVER jerrycan holds up to 18.5 liters at any one time. The LIFESAVER jerrycan was designed to store and carry non-purified or dirty water, so you can filter the water on demand when and where you need to drink it. Filter watered can be used for drinking, washing and cooking. No need for bad tasting chemicals such as chlorine or chlorine dioxide. LIFESAVER microbiological water filters use ultra filtration technology to filter out viruses, bacteria, cysts and parasites from contaminated water sources. LIFESAVER water filters meet an adaption of NSF Protocol 231 based on recommendations of the U.S. Environmental Protection Agency (EPA). LIFESAVER bottles filter bacteria to a minimum of Log 6 (99.9999%), Viruses to a minimum of Log 4 (99.99%) and Cysts to a minimum of Log 3 (99.9%).Here is the link to the LifeSaver Jerrycan instruction manual: http://www.iconlifesaver.eu/documents/LS%20jerrycan%20Manual_SLI0015-2.pdf
