There is no small scale human comparable in room CO2 removal bio/tech. Human breath will increase CO2 in a closed room on the order of many hundreds of ppm over hours, while even "superplants" like those in an Algen Air will decrease it at best on the order of low tens. We need improvements of two orders of magnitude to have room scale impact. So the only answer is "fresh" air ventilation.

Some submersible tech and space tech used rebreathers or scrubbers to remove CO2 and increase O2 levels. Of course the reason it's not common is that outside of those use cases you can generally just open a window.
