Common IAQ Problems & Solutions
Lennox® IAQ Best, Better,
Good Solutions |
|
|
|
Purification
|
|
| Problem |
Odors and Chemical
Vapors
Perfumes, cleaning supplies, paints, pet odors, cooking fumes
and other airborne contaminants |
|
|
Small, Respirable
Particles and Bioaerosols/Microorganisms
Pollen, dirt, pet dander, dust mites, bacteria, viruses, mold |
|
|
| Solution |
Air-purification
systems attached to the furnace or air handler, where contaminants are
removed and destroyed before air is re-circulated into the home |
|
|
 |
Elimination |
|
|
| Problem |
Small, Respirable
Bioaerosols/Microorganisms
Pet dander, dust mites, bacteria, viruses, mold and other contaminants
that can collect on the air conditioning coil, reducing system
efficiency, and circulate through the home |
|
|
| Solution |
UVC
lights dramatically reduce concentrations of potentially harmful
microorganisms |
|
|
|
|
|
 |
Ventilation |
|
|
|
| Problem |
Poor
Airflow
A common problem in newer homes, which are tightly sealed to conserve
energy. Instead of continually moving, indoor air becomes stagnant, and
contaminants have no way to escape. |
|
|
| Solution |
Ventilation systems replace state, contaminated indoor air with outdoor
air - providing the fresh-air feel of an open window, with virtually no
heat/energy loss or safety risk |

|
| Humidity
Control |
|
|
|
| Problem |
Too
Much Moisture
Can make the air feel stuffy and warmer than the actual temperature, and
can also promote the growth of mold, mildew, fungi, bacteria and viruses |
|
|
Too
Little Moisture
Can cause dry skin, sore throats and respiratory problems, along with
annoying static electricity. |
|
|
| Solution |
Dehumidifiers and
humidifiers work with the home's heating and cooling system to keep
moisture levels balanced in every room |
