F50F AND F3OOE ELECTRONIC AIR CLEANERS
Ozone and the
electronic air
cleaner
Aboutlint or
"white dust"
Electronic air cleaners generate a very small amount of ozone,
about 0.005 to 0.010 parts per million (ppm). The amount is
highest when the air cleaner is new.
The average person can detect the odor of ozone in
concentrations as low as 0.003 to 0.010 ppm. The U.S. Food
and Drug Administration, and Health and Welfare Canada
recommend that indoor ozone concentration should not exceed
0.050 ppm. As a comparison, the outdoor ozone level in major
cities is sometimes higher than 0.100 ppm.
If desired, the ozone generated by the air cleaner can be
reduced by asking your dealer to:
• Install an activated carbon filter downstream of the air
cleaner, or
• Adjust the air cleaner power supply to reduce ozone
production.This adjustment reduces ozone production about
20-25 percent, but also reduces air cleaning efficiency about
seven to ten percent.
White dust is made up of particles that settle out of the air
before they get to the return air duct. You can help prevent this
white dust from settling by running your fan constantly and:
• Be sure the return registers are not blocked with furniture.
• Be sure the discharge ducts are clean (best done before
installing the air cleaner).
• Be sure your clothes dryer is vented to the outside and is not
plugged.
• If you have new rugs or drapes or new woolen blankets, be
aware that the lint from these items will reduce with age.
• In new or remodeled homes, plaster dust or paint pigment
may contribute to white dust, but will reduce with time.
• Use of a humidifier may contribute to white dust, especially if
filled with undistilled water.
