HOW ELECTRONIC AIR CLEANING WORKS
The particles removed by the electronic air
cleaner tend to be very small—less than ten
microns. But what is a 10 micron particle? The
eye of an average sized sewing needle has a
diameter of about 750 microns, 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 more than 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.
