CO2 is important because it is a proxy for how much air you are rebreathing. This is especially important because of Covid. If you have a few people in a poorly ventilated room co2 will climb. Whereas in a well ventilated room, it might be nearly as good as being outside.
Even for just being at home this is important because if the air is poorly ventilated it will feel "stuffy". It can affect how well you are able to think and work.
Most air quality meter's only measure pollution, and you have to get an expensive one to measure co2 which is why it is frequently omitted despite importance.
