Clean contaminants from the home

The PureAirt air purification system helps to signif icantly reduce levels of airborne volatile organic compounds, cooking odors, common household odors, airborne dust particles and mold spores, and pollen in residential spaces. The PureAirt air purification system includes a MERV 9 pleated filter (PCO−12C/20C) or MERV 8 pleated filter (PCO−12U/20U), 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 PureAirt air purification system is NOT intended to be used for removal of active mold growth or high levels of chemicals in the air. For existing mold growth, the mold must be properly removed PRIOR to installation of the PureAirt air purification system.

Filtration: Lennox offers a portfolio of products to remove airborne pollutants such as pollen, dust mites, and mold spores: a 1" MERV 8 pleated filter requires quarterly replacement; a 5" MERV 8 pleated filter requires annual replacement; a high−efficiency, collapsible Merv 10 media air cleaner requires annual maintenance depending on the home environment; and an electronic air cleaner which is equivalent to a MERV 10 filter requires monthly maintenance (washing) to obtain maximum energy efficiency.

The MERV rating of a filter describes the size of the holes in the filter that allow air to pass through. The higher the MERV rating, the smaller the holes in the filter, providing enhanced filtration. The dirtier the filter, the better the filtration, however, the filter does need to be changed for maximum efficiency over time. With electronic air cleaners, however, the filtration capability diminishes over time. Filters need proper maintenance to ensure optimal system performance. Filtration products are designed to remove particles and capture bioaerosols, providing a comfortable living environment.

Purification: Organic chemicals are reduced by converting them to carbon dioxide, water and minerals (as done by the PureAirt air purification system).

Molds can be killed or de−activated on illuminated surfaces by the Healthy Climate® germicidal lights. For optimal indoor air quality, the Healthy Climate® germicidal lights are recommended as a companion product to the PureAirt air purification system. Germicidal lights should be installed near the indoor coil to sterilize the surface to preven mold growth on the damp coil.

Monitor the indoor air quality to maintain a

healthy home environment

The air quality in homes should be continuously monitored for temperature and relative humidity (%RH). Ask your Lennox dealer about long−term monitoring of temperature, relative humidity and carbon monoxide levels (CO detector −− X1124), as well as other monitoring options as they become available.

Humidification: Dry, cold air in your home can make your nose and throat feel dry. It may also cause or aggravate other respiratory ailments. It may be necessary to add moisture to your home’s air to ensure comfort in your home and to reduce the occurrence of dry skin, chapped lips and annoying static shocks. The Lennox Healthy Climate® humidifiers [WB2−12 (35X51), WB2−17 (35X52) and WP2−18 (35X50)] are available in by−pass and power models. Of course, these humidifiers are designed to work in conjunction with the PureAirt air purification system.

Maintenance: A healthy climate can be sustained ONLY with regular maintenance of the home system. The homeowner must change filters, germicidal lamps, metal inserts, humidifier pads, etc. Air ducts and indoor coils must be cleaned and units must be properly charged to ensure optimal efficiency. Maintenance is particularly critical if there are people in the home who have allergies, asthma, or other envirnmental sensitivities. The best way to ensure that the HVAC system and optional indoor air quality equipment are well−maintained is to take advantage of a semi−annual service contract offered by your Lennox dealer.

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 to promote improved consumer education about indoor air quality.

Refer to the installation and maintenance instructions included with your new Lennox Healthy Climate® product for recommended maintenance.
