cautious folks:

Carrying a CO2 monitor helps me check how safe the in a space is, and lower or raise my cautions accordingly. (Details: harihareswara.net/posts/2023/m ) Super useful.

I use and like the monitor. The 4 is usually USD$249. It's on sale, direct from the manufacturer, till September 17, for $184.35, with free shipping in the US.

Or from Amazon for $197: amazon.com/exec/obidos/ASIN/B0 (Might be today only - Sept 7th.)

Aranet 4 carbon dioxide monitor measuring air CO2 on an underground New York City MTA subway train in June 2023, showing 955 ppm.
Aranet CO2 monitoring app screenshot from one week in May 2023. Almost all readings are in the green range, under 1,000 ppm. A few hours in the yellow and red ranges, about 1,000 to 2,100 ppm, are during airplane travel. The 5,905 ppm peak is during a car ride.
