HOMEOWNERS’ GUIDE FOR LENNOX HEALTHY CLIMATE®
INDOOR AIR QUALITY PRODUCTS
Methods to Improve Indoor Air Quality
Optimal indoor air quality can be obtained by using four strategies in your home environment:
DEliminate sources of poor air quality;
DVentilate the home properly;
DClean contaminants from the home;
DMonitor the indoor air quality to maintain a healthy home environment.
Eliminate sources of poor air quality
Identify and remove or reduce the sources of poor indoor air quality in the home. Pollutants which may affect indoor air quality include:
Dirt and Dust: Prevent filtration of dirty air and dust from unconditioned spaces (i.e. attics) into the HVAC system. Seal the ducts using mastic or aluminum foil 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 and Chemicals: Remove sources of odors and chemical contamination from the home and use products that minimize contaminant levels in the air. Lennox’ PureAirt air purification system removes and destroys odors and chemicals.
Mold: Minimize mold by controlling moisture in the home. Prevent roof and water pipe leaks. Contact a contractor if your home develops a water leak.
Control the relative humidity in the home to keep it between 30 percent and 50 percent. Contact your Lennox dealer about products that reduce the humidity levels in the home [variable speed air handlers, furnaces and compressors, humidity controls and dehumidifiers (85X74)].
If mold is in the home, it must be properly removed. After the mold has been removed, Lennox’ Healthy Climate® PureAirt air purification system [model PCO−12C (75X69), PCO−20C (75X61), PCO−12U (X1179) and PCO−20U (X1183)] will help to remove mold spores from the air.
Optional Healthy Climate® germicidal lights [models UV−500 (46X85), UV−1000 (46X87) and UV−2000 (46X89)] greatly reduce new mold growth on illuminated surfaces.
An accumulation of dirt and dust in the air ducts provides 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 significant existing active mold growth, you should contact a company that specializes in mold removal. Lennox is a sponsor of the Indoor Air Quality Association (IAQA). Contact the IAQA (phone: 301−962−3804 or web: www.iaqa.org) or your state’s health department for a list of companies which specialize in mold removal and training.
Ventilate the home properly
Contaminants in the home can be reduced by adequate ventilation. Open windows will allow natural ventilation; however, this is not a good option for people who are sensitive to pollutants in the outdoor air (pollens, chemicals, etc.). Lennox’ Healthy Climate® Energy Recovery Ventilators [models ERV1−150 (64X66) and ERV1−200 (64X69)], Heat Recovery Ventilators [models HRV1−150 (64X65) and HRV1−200 (64X67)] and Ventilation Control System [model LVCS (X4141)]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. Clothes dryers should be vented to the outdoors also. 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 PureAirt air purfication 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.
