PUREAIR™ AIR PURIFICATION SYSTEM
HOMEOWNERS IAQ GUIDE FOR PUREAIR™ MODELS PCO-12C, PCO-20C
GENERAL
The PureAir™ air purification system helps to significantly reduce levels of airborne volatile organic
compounds, cooking odors, common household
odors, airborne dust particles and mold spores,
and pollen in residential spaces. The PureAir™ air
purification system includes a MERV 9 Pleated
Filter, UVA lamps, and a Metal Insert that is coated
with a titanium dioxide catalyst. As air enters the
system, a percentage of airborne particles and
bioaerosols, such as mold and bacteria, larger than
.3 microns are captured by the pleated filter. The
smaller airborne particles, odors, and chemicals
continue through the system. The UVA lamp activates the catalyst on the Metal Insert. The catalyst
combines with water vapor in the air to form
hydroxyl radicals that destroy a percentage of the
remaining odors and chemicals.
The PureAir™ air purification system is NOT
intended to be used for remediation of active
mold growth or high (industrial) levels of chemicals in the air. For existing mold growth, the
mold must be remediated by a qualified service
provider PRIOR to installation of your PureAir™
air purification system.
NOTE: If there is a sudden source of contamination
in your home [caused by burned food, cleaning an
oven, painting or hobby work that releases chemicals (model airplanes, soldering, furniture finishing,
etc.)], the PureAir™ air purification system WILL
NOT reduce the odor immediately. In cases of sudden source contamination, open windows and
doors to rapidly reduce the concentration of the
contaminant.
INDOOR AIR QUALITY(IAQ) METHODS
Optimal indoor air quality can be obtained in a
home by using source reduction, ventilation,
humidification, and purification methods.
SOURCE REDUCTION
Identify and remove or reduce the sources of poor
indoor air quality in the home. Specific pollutants
which may affect indoor air quality include:
212512-00 Rev. 1B 5/02
©2001 Lennox Industries, Inc.
Dallas, Texas USA
Dirt & Dust: Prevent leakage of dirty air and dust
from unconditioned spaces (i.e. attics) into the
HVAC system by sealing the ducts with mastic or
aluminum tape along all joints. Use a vacuum
cleaner equipped with a HEPA filter to permanently
remove small dirt particles rather than simply redistributing them, as is the case with a conventional
vacuum cleaner.
Odors/Chemicals: Remove sources of odors and
chemical contamination from the home and use
products that minimize contaminate levels in the air.
The new PureAir™ air purification system removes
and destroys odors/chemicals.
Mold: Minimize mold by controlling moisture.
Prevent roof and water pipe leaks and it is recommended that relative humidity be kept between
30%-50%. Contact a contractor if you have a water
leak. Ask your Lennox dealer about products that
reduce humidity levels in the home [variable speed
air handlers/furnaces/compressors, humidity controls and dehumidifiers (85X74)].
Once the mold is removed by a qualified mold
remediation company, the Healthy Climate™
PureAir™ air purification system [models PCO-12C
(75X69) and PCO-20C(75X61)] will help to remove
low level mold spores in the air.
Optional Healthy Climate™ Germicidal Lights
[models UV-500 (46X85), UV-1000 (46X87) and UV2000 (46X89)] greatly reduce new mold growth on
illuminated surfaces.
An accumulation of dirt and dust in the air ducts
creates an ideal site for mold growth. To ensure
optimal indoor air quality, non-porous insulation or
externally insulated ducts should be used, particularly on the supply side (i.e. externally insulated
metal plenums and ducts or, smooth-lined flex duct
are preferred).
If your home has existing active mold growth, you
may need to work with a company that specializes
in mold remediation. Lennox is a sponsor of the
Indoor Air Quality Association (IAQA). Contact the
HOMEOWNERS IAQ GUIDE FOR PUREAIR™ MODELS PCO-12C, PCO-20C
air purification system. These products should be
installed near the A/C coil to help prevent mold
growth on the damp coil.
MONITORING and MAINTAINING IAQ
The air quality in homes can be continuously monitored for Temperature and Relative Humidity
(%RH). Ask your Lennox dealer about long-term
monitoring of T & %RH and CO (carbon monoxide)
(72N00), as well as additional monitoring options
for additional IAQ parameters as cost-effective
options become available. Also available is a Total
Volatile Organic Compound (TVOC) test kit,
processed by an independent analytical lab, that
identifies the level of chemical contaminants in the
home (Part. No. X0264).
A healthy climate can ONLY be sustained with regular maintenance of the home system. In order to
maintain optimal performance, the homeowner
must change filters and lamps on the PureAir™
system, change humidifier pads on the humidifier,
change germicidal lamps on each UV germicidal
unit, keep the air ducts and air conditioning coils
clean and properly charged, etc. The best way to
ensure that the system is properly maintained is to
utilize a semi-annual service contract offered by
your Lennox dealer. The system should be
checked for optimal performance with routine
maintenance performed at the beginning of every
heating and cooling season. Maintenance is particularly critical if there are people in the home with
allergies, asthma or other environmental sensitivities.
For a better understanding of the triggers that are
related to allergies and asthma, please contact the
Asthma and Allergy Foundation of America
(www.aafa.org). Lennox is a sponsor of the Asthma
and Allergy Foundation of America for improved
consumer education of IAQ.
ROUTINE MAINTENANCE
Refer to the PureAir™ Air Purification System
Installation and Maintenance Instructions for the
details of the recommended maintenance.

or your state's health department for a list of companies which specialize in mold remediation and
training.
VENTILATION
Contaminants in the home can be reduced by adequate ventilation. Natural ventilation can be used
by opening windows. Open windows are not a
good option for people who are sensitive to pollutants in the outdoor air (pollens, chemicals, etc.).
Healthy Climate™ Energy Recovery Ventilators
[models ERV1-150 (64X66) and ERV1-200 (64X68)]
and Heat Recovery Ventilators [models HRV1-150
(64X65) and HRV1-200 (64X67)] can provide filtered ventilation. If you, or someone in your family
is sensitive to outdoor pollutants, ask your Lennox
dealer about these products. Exhaust fans which
vent stale or contaminated air to the outside should
be installed in the kitchen, bathroom(s) and laundry
areas to effectively remove contaminants. If there is
a sudden source of contamination in your home
[caused by burned food, oven cleaner, paint or
hobby work that releases chemicals (model airplanes, soldering, furniture refinishing, etc.)], the
PureAir™ air purification system WILL NOT reduce
the odor immediately. In cases of sudden source
contamination, open windows and doors to rapidly
reduce the concentration of the contaminant.
HUMIDIFICATION
Dry, cold air in your home can make your nose and
throat feel dry, and cause or aggravate other respiratory ailments. By adding moisture to your
home's air, and maintaining proper moisture levels,
the Healthy Climate™ Humidifiers [models WB2-12
(35X51) and WB2-17 (35X52) and WP2-18 (35X50)]
keep you comfortable in your home by reducing
the occurrences of dry skin, chapped lips, and
those annoying static shocks. The Healthy
Climate™ Humidifiers come in by-pass and power
models, and work well as a companion to your
PureAir™ air purification system.
PURIFICATION
Chemicals are converted to carbon dioxide, water
and minerals (PureAir™ air purification system) and
molds are killed or inactivated (Healthy Climate™
germicidal lights). For optimal indoor air quality the
Healthy Climate™ Germicidal Lights are recommended as a companion product to your PureAir™
