How this sensor could help reopen indoor spaces

As we begin to creep back to work, restaurants, and theaters, we want to know how much potentially diseased breath we are rebreathing. Armed with a CO2 monitor we went to places we frequently visit to see just how much breath is in the air. Is this the best way to monitor?

[@pavegray]

Carbon Dioxide is used as a metric to gauge indoor air quality (IAQ) and ventilation system efficacy (most specifically air changes within a volume over time). In the United States, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) publishes guidelines (consensus standards - best practices not having force of law unless specified as such by a regulatory entity) for IAQ. The Occupational Safety and Health Administration (OSHA) considered development of an IAQ standard(s) for employers in 2011, but felt that individual local and state occupational safety and health (OSH) entities were doing well enough without a federal standard. Hence, besides local and state OSH IAQ regulatory (e.g., having force of law) standards where they exist, there is no national IAQ regulatory standard. What would be most useful is the development of an estimated ratio of CO2 concentration to concentration of potential SARS-CoV-2 virion/other infectious agent containing bioaerosols.

"The outside air naturally has around 400ppm CO2" natural in that context sounds really wrong. Without us burning fossil fuels, it would be around 300ppm. The comment about the 400ppm sounds like a way to minor side node for the consequences it has, in my opinion.

[@mikesimons66]

There is nothing natural about the outside air having 400ppm CO2

[@jameswarner7435]

Actually there is nothing all that unnatural about it either if we take into account that Earth's atmospheric co2 levels are estimated to have ranged between 400 and 1000 ppm for the greater part of the last 400 Million years. It was really only over the past million years or so that atmospheric co2 concentrations dropped to a low of around 300 ppm. The natural processes that drove the 700ppm decline from 1000 ppm down to the relatively recent lows of around 300ppm are surely capable of absorbing the 100 ppm we think humans have contributed to today's atmosphere. Besides, due to it's overlap with the IR absorbed by water vapor, the IR absorption potential of atmospheric co2 is fully saturated at 300ppm, and any increase in co2 ppm beyond that level has a rapidly diminishing effect on atmospheric thermodynamics. After all, it's physically impossible to absorb more than 100 percent of something! So to say if todays levels natural or not is really a matter of how much of earth's history we're comparing it to. But either way, I'm not convinced the additional co2 we've added to the atmosphere poses a significant problem at all.

[@bbt305]

Should have trued different machines too!

[@KingQuetzal]

Another cool thing this CO2 sensor will do it let you know how atmospheric CO2 is increasing leading to ocean acidification and coral bleaching

[@jobigoud]

Not really because to avoid sensor drift these devices have an auto calibration system that uses a fixed reference of 400 ppm set at the factory.

Decreasing CO2 is an overall benefit. At certain ppm thresholds brain function gets significantly impaired. This is a real issue at schools

I got excited that the CO2 monitor would be modified to detect specific viral particles. But no, its just checking CO2. Pretty worthless. Pretty much all air you breath in that comes from other people, is technically "infectious air". But we don't get sick every single time we encounter other peoples breath or breath back in our own. Why is that? Checking to see if people have been breathing in a spot, not useful. Checking to see what the density of a specific particle in parts per million, would be.

[@QueenCornana]

The CO2 meter lets you know if you or the building you're in needs to improve their ventilation systems. It's not a spot reader, but a whole room reader. For example, you can use a meter to check the air quality in an airplane (you may want to wait until take off to unmask to eat that snack). The goal is to have lots of air changes per hour. One way to improve air quality is by simply opening a window (obviously) , but installing Merv 13 filters, which can actually filter out airborne pathogens, is a real game changer. If you have to have a stranger come over (for repairs or something), you could do a combo of opening a window and turning on an air filter (or make your own CR Cube). The higher the CO2 levels, the less people you want in an unventilated room, pandemic or not. If you find yourself getting really drowsy & disoriented all of a sudden, the CO2 levels inside the room may be way too high!
