At risk of going wildly off topic from the post, I’d suggest that for anybody with disposable income, the value proposition of buying some air quality sensors is amazing.

I installed some a month or two ago, and they caught alarmingly high radon levels in my basement that I’m now working to address. But also they catch more mundane things, like “oh, I tend to get headaches in the afternoon, which happens to be when the co2 levels are super high in my office”.

Which brand of sensors do you recommend?

I’ve been happy so far with Airthings. They have a variety of sensors with different price points / features (seems like most except the Mini will do radon), the mobile app is decent, and there’s a HomeAssistant integration for it.
