CO2 monitors measure the amount of Carbon Dioxide in the air, and can help determine if an indoor space is well ventilated.
“Infectious people exhale airborne viruses at the same time as they exhale carbon dioxide. That means CO2 can serve as a “proxy” for the number of viruses in the air.”
“Even if you’re physically distancing and washing hands, COVID transmits in the air, so we need to make sure we have good indoor air quality,” says Ms Cole, who is also president-elect of the Australian Institute of Occupational Hygienists.
It is important to choose a CO2 monitor with an NDIR sensor (Non-dispersive infrared sensors) as they are the most accurate for gauging ventilation.
Aim for under 600ppm to best mitigate COVID risk.
