The particles removed by the electronic air
cleaner tend to be very small—less than 10
microns. But what is a 10 micron particle? Well,
the eye of an average size sewing needle is
about 750 microns across, and the dot in the
i
in
the word micron is about 400 microns. Gener-
ally, particles smaller than 10 microns can be
seen only with a microscope, except in very
large concentrations, such as a puff of smoke.
Your electronic air cleaner can remove even
smaller particles that can be seen only with an
electron microscope.
Although particles 1 micron and smaller make
up only about 20 percent of the total
weight
of
particles in unfiltered air, they account for over
99 percent of the
numbers
of particles.
Because they are so tiny, these particles tend to
remain suspended in the air unless they collide
with a solid surface. Then they attach by
molecular adhesion and stick like glue, staining
walls and furniture and coating your air condi-
tioning coils. And of course, some of these
particles can cause allergic reactions or simply
make the environment less pleasant.
