I wonder if with the research on CO2 effects, if we will start to get CO2 filters in common appliances such as indoor heating and cooling equipment.

Places like the International Space Station already have to deal with this because they can't just open a window.

IIRC, lime or something like that can be used as a carbon scrubber, but it's not something that you'd want to do constantly and everywhere. Looked this up some time back.

Soda lime.

https://en.wikipedia.org/wiki/Soda_lime

Soda lime is a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO). It is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats. Its purpose is to eliminate carbon dioxide (CO2) from breathing gases, preventing carbon dioxide retention and, eventually, carbon dioxide poisoning.[1][2]

Probably, if you want to regulate CO₂ levels in HVAC systems, best to ventilate to the outside and then run the exchanged air through a counterflow heat exchanger to preserve indoor temperature as much as possible.

Oh I’ve got some limes.

Oh, well I can go get some of that.

Oh, so it’s not lime soda. It’s soda lime. Alright then… I’ve got some salt and milk.

Wait, I’m not supposed to drink it?
