no one should worry about CO₂ at all in their homes or offices. only workers in certain industries/factories, where CO₂ can get several orders of magnitude higher, need to be concerned at all about it. you (here and in your marketing materials) are stoking needless anxiety over a gas that life on earth literally requires.

pollutants, on the other hand, and particularly particulate matter (especially chemicals that we've manufactured recently in human history), do have proven negative health consequences and should be monitored and mitigated in the home and office. it's estimated that over a million people a year die prematurely of respiratory and cardiovascular complications due to pollution.

in short, a lack of CO₂ monitoring in favor of PM and VOCs by ikea should be seen as a plus, not a minus here.

note that VOCs are typically estimated from cheap CO₂ sensors, and are likely to be highly unreliable as a result, but more accurate (and more expensive) VOC sensing is possible, e.g., https://www.degruyter.com/document/doi/10.1515/revac-2021-01...
