The particles removed by the electronic air cleaner tend to be
very small--less than ten microns. But what is a ten-micron
particle? 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. Generally, particles smaller than ten
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 one 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 conditioning
coils. And of course, some of these particles can cause allergic
reactions or simply make the environment less pleasant.

How the
electronic air
cleaner works
First, large particles (lint, hair) are caught by the prefilter(s).
Then, as the dirty air passes through the intense high voltage
electric field surrounding the ionizer wires, all particles, even the
smallest particles down to 0.3 micron are given an electric
charge.The air then passes into the collector where the
alternate parallel plates are charged positive and negative,
creating a uniform electrostatic field. Since opposites attract,
the charged particles stick to the collector plates, having an
