LIFESAVER Jerrycan 10000UF replacement cartridge removes bacteria, viruses, cysts, parasites, fungi and all other microbiological water-borne pathogens from your water and will filter up to xx gallons (xx liters) of water before it needs to replaced.

Failsafe technology – When the bottle requires a significant number of pumps to induce water to flow this indicates that it is nearing the end of its life. When no more water can be induced to flow despite continuous pumping, the cartridge has expired and it is time to replace it.
