Vestergaard LifeStraw Mission User manual

Product set-up
LifeStraw® Family uses ultrafiltration
hollow fiber technology
This is a highly eicient
method of purification that
requires no chemicals.
Water is forced through
narrow fibers under low
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.
NOTE: Water from the red dirty water
valve should never be consumed.
