Works, is easily transported
We use this as a proxy for ventilation and air flow in small spaces like doctors treatment rooms or outpatient clinics. I am immunocompromised and must take care of myself. We've tested it at home and driving and you can see how the CO2 level changes with more people or more ventilation. Any CO2 level over 800 is considered the bare minimum of adequate ventilation by environmental engineers according to my reading, but do your own research. I was surprised how little ventilation many places had that I tested, I was breathing a lot of stale air with who knows what bacteria or viruses floating around. Whatever you use it for, it works and you can stuff it in a purse or backpack for travel.
