An opinion I feel should be universal at this point: All indoor public spaces (but especially schools, workplaces, and medical facilities) should be subject to air quality regulations and continuous monitoring and CO2 and particulate concentration numbers should be accessibly displayed.

Some indoor spaces have great ventilation — show the public that.
You can't get 800- ppm with low consumption unless you destroy 99.9% of building stock. Just not the way it works
Air should be safe
But you need a different mix: filtered ventilation, hepa & upper-room UVGI
This gives safety, today, everywhere
tl;dr 100% agree - we monitor, filter, and regulate indoor air the same way we do our water.
IAQ standards are woefully under adopted and are in fact resisted at every level of govt by developers/contractors and their republicans. It’s somehow still a tough political environment despite over a million dead from an airborne pathogen.
I'm sitting in my office right now and I'm at 1001 CO2 ppm, which is kinda high. (High enough to affect cognition.) My window is open but I probably need to open my door.
Moving out of a city CBD apartment into the mountains just over a year ago has done far more for my health though!

So much coughing yesterday.
Yes i eat out in public - but off peak, and everything else i do masked.
And I don't even know if it takes into account environmental pollution, like soot that may deposit on the (optical) detector window
And given the size of the beam, a small amount is probably enough to disrupt measurements
It is perfectly viable to require that all buildings open to the public have a certain quality filtration.
Likewise having outdoor vents for stoves with proper emission controls.

(So naturally we won't do it.)
