LifeStraw Family is a large volume water purifier providing up to 4750 gallons or 18000 liters of water, enough to supply a family of five with clean drinking water for up to three years. It's useful to have at home to purify contaminated tap water in the event of boil water advisories or emergency situations. LifeStraw Family uses advanced hollow fiber technology. Water is forced through narrow fibers under high pressure. Clean water exits through tiny pores in the walls of the hollow fibers, but bacteria, viruses, protozoa and other contaminants are trapped inside the hollow fibers and are flushed out by backwashing. This is a highly efficient method of filtration.

How LifeStraw Family Works
The feed water bucket (2 liter capacity) is filled with water.
The 80-micron textile pre-filter (inside the feed water bucket) removes coarser particles and is easy to clean.
Water passes through the meter-long blue PVC hose and gravity creates sufficient pressure on the membrane cartridge in order to reach a high flow rate.
Ultra filtration takes place in the hollow fiber membrane cartridge - a pore size of 20 nanometers (0.02 microns) retains bacteria, viruses, parasites and fine dirt particles.
The blue tap is turned to release purified water.
Backwash the membrane by squeezing the red backwash bulb 3 times with both taps closed and then releasing the dirty water from the red tap. Water from the red tap should never be consumed.
