Inside an
ionizing air cleaner
Unlike HEPA
air cleaners, shown at bottom,
electrostatic precipitator air
purifiers impart an electrical
charge to the air, creating
charged molecules known as ions,
which are supposed to cling to
airborne particles.
Electrostatic precipitators add
an oppositely charged collection
plate or filter designed to
attract the particles. Ozone is
produced as a byproduct, which
then exits the machine and flows
into the room air.
|
|
Ozone is created
as high voltage
converts oxygen
to ozone. All
electrostatic
precipitators
can create
ozone, though
some emit more
than others.
Some people
mistake ozone's
sweet smell for
a sign of
cleaner air.

Inside HEPA air
cleaners
|
|
Models with a
high-efficiency
particulate air
(HEPA) filter
are most common.
Typically, a fan
pulls air
through a foam
pre-filter
designed to
remove some
larger
particles. The
air is then
forced through
the pleated HEPA
filter, which is
designed to trap
most particles.
The air might
then pass
through a carbon
filter to remove
odors. Sometimes
the carbon
filter will take
the place of the
pre-filter.

Inside an ozone
generator
|
|
Room air passes
through a
high-voltage
plate, where
some oxygen
molecules are
ionized. The
ions combine
with oxygen to
form ozone. The
size of the
generating plate
and the amount
of electrical
current will
affect the
amount of ozone
produced.
Generally, ozone
generators emit
high levels of
ozone, so they
are not meant
for routine air
cleaning. They
should be used
only by
professionals in
unoccupied areas
after serious
contamination
has occurred in
the home, say
from a fire or a
flood. |
