How does the Smart Air Quality Monitor work?
FAQ , Air Purification , Troubleshooting Modified: March 19, 2026
The Lennox Smart Air Quality Monitor detects and tracks particulates, carbon dioxide and volatile organic compounds (VOC's) inside the home. When poor quality air is detected, it triggers your system to cycle and clean the air, providing peace of mind that your family is breathing the most healthy, perfect air.
When your HVAC system includes Healthy Climate® indoor air quality products, it can more effectively address the problems it detects. In fact, the Lennox Smart Air Quality Monitor is the only monitor available that enables on-demand ventilation, purification and filtration based on real-time air quality readings.
