Cool
A turbine pushes
air into the three-
foot-tall device’s
oval-shaped head,
which blows a fo-
cused gust out of the
front, the back, or
both as it oscillates.
A “breeze mode”
mimics natural wind.
Humidify
As water travels from
a tank in the base, UV
light kills almost all
bacteria. From there,
H 2 O passes through a
mesh (below) that
turns it into a mist
whose particles are
too small to carry
leftover baddies.
Filter
Fan-bound air flows
in through a grate,
and then a HEPA filter
pulls out allergens as
small as 0.3 microns,
like pollen or mold.
Smelly molecules that
make it through get
stuck on a grid of ac-
tivated carbon.
