Ozone and the electronic air cleaner
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.
About lint or "white dust"
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.
