And even absent the virus, each public areas and houses can accumulate excessive ranges of CO2 from on a regular basis actions—not simply respiratory, however from utilizing gasoline stoves and water heaters. We contacted a researcher to speak about utilizing CO2 displays for air high quality measurements, and collectively we got here up with a product suggestion, in addition to some recommendation on the way to interpret and react to its info when monitoring CO2 at residence.
