cooling equipment where it is conditioned and sent back into the rooms
of your house through the supply ducts. Small particles from numerous
sources are suspended in your home's air, just as they are suspended in
the air outdoors. The largest of these particles will eventually come to rest
and appear as dust. Smaller particles may come to rest, but with even the
slightest disturbance will re-suspend into the air. These particles are very
small, and come from natural sources such as dust and pollen and from
man-made sources such as tobacco smoke or exhaust. The air cleaner
is installed on or near the furnace/air handler and removes the particles
that travel with the air that circulates through your heating and cooling
system. Removing these particles keeps the equipment components
clean and more importantly removes particles from the air you breathe.
Particles are measured in microns, which is a unit of measure used for
very small things (1 micron = 1/25,400 inch). For reference, the diameter
of a human hair is approximately 100 microns. FIGURE 2 shows the size
of various particles that can be found in the air.
