I wonder when will personal CO2 scrubbers become a norm. With atmospheric CO2 growing ever higher and everyone having a CO2 detector (and an air "purifier") at home it's the next step.
Probably never. 1000ppm seems to be a value where the concentration has some negative effects.
you mean... plants? plants scrub CO2.
Plants scrubbing co2 indoors are pure placebo. You would need to convert half of your apartament with a tropical jungle to offset what you breathe out.
