 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
