i want a small scale version of this to scrub CO2 out of my office (not too different than what they do on submarines). i already dump out a dehumidifier every day, could imagine swapping the "carbon brick" along with it (yes yes -- fresh air exchanger on the HVAC system would also do this, but i want gadgets)

Well, you could grow algae as a CO2 sink! https://youtu.be/64cEmjtwRgw?si=QmRd716sgFmjaM-0 https://youtu.be/64cEmjtwRgw?si=QmRd716sgFmjaM-0

I realize your suggestion is surely not practical, but at the same time it's got my curiosity now. How big would such a brick have to be to absorb all of somebody's CO2 for a day? I just have no intuition whatsoever around it. (Also you'd need a carbon filter for all of the VOC's as well.)
