The IAQ Mini is designed to give immediate and obvious notification of indoor air quality levels. As CO2 levels increase, the large LCD display changes from green to yellow to red to make it easy to monitor the CO2 level from anywhere in the room.
In addition to CO2, the display shows temperature, % relative humidity and a bar graph that records the CO2 level history over the last 24 hours. For nighttime use, the display will go dark from 10pm until 6am.
The IAQ Mini can be easily calibrated by taking it outside and starting the calibration process in outdoor air.
Indoor Air Quality Monitors and COVID-19 in Schools
COVID-19 is becoming an issue as children return to school this fall. A CO2 monitor can give an accurate description of classroom air quality. High CO2 levels in the air correlate with high levels of airborne dust, dander, mold, particulate matter, chemicals and aerosolized liquids that can carry the coronavirus. Learn more about COVID-19 and CO2 monitors here.
The Federation of European Heating, Ventilation and Air Conditioning Associations (REHVA) has recommend using “traffic lights” controlled by CO2 monitors in enclosed areas like classrooms, where green, yellow and red denote good, problematic, and bad air quality. In addition, the Center for Disease Control and several states are now encouraging the monitoring of CO2 levels in schools to raise awareness of IAQ.
Note that indoor air quality monitoring is only one in a layer of a multi-faceted strategy for combating COVID-19 transmission. For an in-depth discussion of this issue watch this hour-long presentation by the National Collaborating Centre for Environmental Health of Canada.
