Don't forget too, if the CO2 is 1000 ppm, then half of the air in each breath you inhale was recently exhaled by someone else. Yes, airborne viruses are still spreading. I still wear an N95 mask whenever I'm in an indoor space with other people outside of home.

IKEA now has a remarkably cheap ($35) air quality monitor that measures CO2 as well as PM:

I don't have one yet but plan to pick one up soon. A CO2 sensor alone from Adafruit is $50+, though that one is more precise. I bought it a while ago and it's still sitting in my todo bin.

I do not give a damm about masks, but yet another reason to prefer work from home.

Flu and other air transmited diseases should be treated as a workplace injury, with proper compensation!

Would that not induce a responsibility to take reasonable preventative measures like wearing masks?

Maybe, but masks do not work. You have to replace it every 30 minutes to preserve filtering capabilities And most germs transfer over touch.

I want this implemented to fullest, preferably with full hazmat suit. Yet more reasons to support work from home.

		I haven't heard that 30 minute figure before, you have a reference? I've seen articles about medical workers using masks for much longer. Installing air filtration and UVC in classrooms and meeting rooms certainly helps. Since the mask shortage cleared up, HCW have been advised to stop re-using them. I re-use mind til they get dirty, but maybe I should replace them more often. https://apnews.com/article/fda-n95-masks-plentiful-should-no...

Doing that all the time might not be the best idea for your immune system and neither for the respiratory one too.

The first needs to occasionally see new threats to stay up to date and healthy. The second will not like the constantly restricted airflow.

could you observe an effect on your health after starting to wear the mask? like sickness days per year?
