Why HN links it
HN readers link this blog's posts on monitoring carbon dioxide as a proxy for disease aerosols and indoor ventilation risk. Comments cite the earlier background post and discuss CO2 monitor readings at home.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
The previous post is essentially the background on this topic: https://grieve-smith.com/ftn/2026/02/so-you-want-to-monitor-... > Why carbon dioxide? Because everyone who exhales COVID (or flu, or RSV) aerosols also exhales carbon dioxide, and good ventilation removes both disease aerosols and CO2. Under many conditions, the concentration of CO2 particles in a space can give us an idea of how much risk there is of ca…

HN discussionThe article linked in the first paragraph is almost more interesting to me[1]. Some of these places, like the subway, have air frequently circulated that can filter aerosols but leave CO2, or at least this limitation makes me somewhat doubt its usefulness as a proxy for disease transmission risk. Apart from disease transmission, since I've gotten a CO2 monitor in my apartment I've noticed that running the gas stove…
