Verifying that the thing scrubs CO2 at the expected rate is definitely a good idea. Verifying the behavioural effects is much harder—you’d need to avoid unblinding, and ideally have several different people with varying levels of age, fitness etc, and then you’d get affected by weather, unless your house is very well sealed...
How portable can this scrubber be? If you’re somewhere cold and not getting enough air at night and it’s your house, you could install a heat recovery ventilator. There is evidently a big market for portable air conditioners, despite their inefficiency; the description of this thing (water, air, pumps out sludge) sounds a lot like a washing machine.

Not really. There’s scads of behavioral measures you can collect passively.
No you don’t, and blinding is easy if you think about it for a few seconds, see the comment I left well before yours.
No, you don’t, you are letting perfect be the enemy of better
This is a feature, not a bug.
