The particles removed by the electronic air
cleaner tend to be very small—less than 10
microns. But what is a 10 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 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 one micron and smaller make
up only about 20 percent of the total
weight
of
particles in unfiltered air, they account for more
than 99 percent of the
number
of particles.
Because they are so tiny, these particles 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 some of these particles can cause allergic
reactions or simply make the environment less
pleasant.
