How CO2 sensors might help us return to ‘normal’

Article note: We should be doing this anyway, we chronically under-ventilate spaces, but if the fact that COVID-19 preys on our badly engineered indoor environments is what will get it changed, let's go. Every meeting room should be equipped with a CO2 detector that shows the current level in ppm and alerts "Effectively drunk" somewhere around 1000-1200ppm. And, of course, this is the highly effective mitigation everyone has been ignoring because it requires institutions spend money to fix.

One of the things we’ve learned over the past year is to be wary of the air around us — especially indoors. If other people are around, exhaling, they’re filling the space with their breath. If one of those people has COVID-19, they could be filling the space with infectious breath.

There’s a way to make indoor spaces safer, though: improving the ventilation to make sure the air doesn’t stay trapped. That way, any potentially infectious particles quickly gust away, instead of lingering for someone else to breathe in.

Experts say one way to measure how well-ventilated certain spaces are is by checking how much carbon dioxide is in the air. People exhale carbon dioxide, so the amount of it in a room gives you an idea of how much of the...
