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.

Make sure the furnace or air conditioner blower 
is running.

Make sure the access door is firmly closed and 
latched. If door is not closed properly, an inter-
lock keeps the air cleaner off.

If the electronic cell(s) are wet from washing, 
turn the air cleaner off for two to three hours.

Check the cell(s) for broken ionizer wires or bent 
plates. Repair if necessary.

Wash cell(s) and prefilter(s) if dirty.

Make sure the furnace or air conditioner fan is 
running.

Make sure the access door is firmly closed.

Make sure the On-Off switch is in the On posi-
tion.

On models without the Solid State Performance 
Indicator, if the electronic cell(s) are wet, check 
again in two to three hours.

You smell ozone and find it objectionable
Call your heating and air conditioning dealer.

Guarantee
If you properly maintain 
your new Honeywell 
Electronic Air Cleaner 
(EAC), Honeywell 
guarantees that if your 
indoor coil requires 

cleaning within the next 10 years, Honeywell will pay 
to have it professionally cleaned by a qualified 
contractor:
—  75% of the cost (up to $150) when installed with a 

Honeywell Coil Irradiation Ultraviolet Air Treatment 
System or

— 50% of the cost (up to $100) if a Honeywell EAC is 

installed without a Honeywell Coil Irradiation 
Ultraviolet Air Treatment System).

• The UltraClean Coil Guarantee™ applies to any 

Honeywell Electronic Air Cleaner properly installed 
with a heat pump, air conditioner or high efficiency 
furnace that is: brand new, less than one year old; or 
more than one year old with the indoor coil 
professionally cleaned by a qualified contractor 
prior to installation.

• Proper maintenance on the EAC means: keep the 

power switch in the On position, periodically verify 
power operation, and wash electronic cells 
periodically as specified in this Owner’s Guide.

• Proper maintenance on the Electronic Air Cleaner 

means: periodically clean the lamp glass and 
replace UV lamps as specified in the Owner’s Guide.
