5. Turn on the air cleaner. If the cell(s) and prefil-
ter(s) are wet, the neon light may not come on
and you may hear arcing. If the arcing is annoy-
ing, simply turn the air cleaner off for two to
three hours or until the cell(s) are dry.
HOW ELECTRONIC AIR
CLEANING WORKS
A word about particle size
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 opposite electric charge.The
precharged postfilter continues to remove small
particles from the air. The air leaving the air cleaner
contains very few particles.
Each time the air circulates through the heating/air
conditioning system and air cleaner, more particles
are removed. These particles are generated by normal
household activities and also enter the house from
outside. That is the reason we recommend that you
use the air cleaner as much as possible.
Electronic air cleaner vs standard
furnace filter
The regular furnace filter collects mainly large, visible
particles that reach the filter. Its main purpose is to
protect the furnace and air conditioner blower. The
electronic air cleaner collects these large particles
plus many of the smaller, mostly invisible particles. Its
purpose is to reduce indoor air pollution as well as to
protect the blower, air conditioning coils and heat
exchanger.
