This device measures:
-CO2 concentration
-relative humidity
-atmospheric pressure
-temperature
I spent ~$200 on Amazon. It pairs with your phone and you can watch data come in every minute or so.

I recently bought one of these air quality monitors and got to take it out for some measurements!
I'll share some findings in this thread.
CCing @CO2Guerrillas here, in case they would like to share.

A great way to see how much clean air you are getting is to measure CO2 concentration.
Too high -> you could use more ventilation -> open some windows!
Outdoor CO2 concentration should be about 400 ppm. I haven't calibrated my device yet, so I measured ~470. Close enough.
<800 is good for indoors. Something like 2000 is very bad.

If I crack some windows, even just barely, it gets down to ~600 ppm very quickly, and my heater can keep the apartment ~70 F no problem.
CO2: 937 ppm.
Not great, not horrible. Surprisingly (to me), this place had the highest CO2 on my trip. It did have a purifier, which was nice.
~700 ppm. Still good.
650 ppm. Not bad!
Fun fact: this shop is 103 years old now.
Basically the same results in both: 650-700 ppm
620 ppm. Still not bad!
The doors open often, and the AC was on.
560 ppm.
Very nice! Especially since my device reads ~470 outside.
Took this sample in the essential ideology section.
520. Still good!
The whole store had their AC up very high. I could see many of the signs shaking due to airflow inside. I assume they were piping in outdoor air.
