LifeStraw ® is a portable water filter
that can be carried around with the
user. Water is drunk directly out of
the filter apparatus - the user dips
LifeStraw ® into a water source and
sucks on it like a straw to draw the
water up. The personal filter is
recommended for adults and
children over 3 years old. The filter
is recommended for use when
away from home.
LifeStraw ® contains a chamber with
a specially developed halogenated resin (containing iodine) that
kills bacteria and viruses on contact. Micro-filters are also used to
remove all particles larger than 0.2 microns (m). Activated
carbon adsorbs residual iodine, improving the taste of water. The
filter will remove some turbidity. More frequent backwashing will
be required if the source water is turbid.
Must be purchased from Vestergaard Frandsen (regional offices
located in parts of Africa and Asia) and imported
Requires no electricity or spare parts. The outer shell is
composed of high impact polystyrene plastic. Can be carried
around by the user on a string around their neck. Should be
regularly backwashed by blowing through it to prevent clogging;
will require more frequent backwashing if turbid water is used.
