#COVID19 #COVID cautious folks:

Carrying a CO2 monitor helps me check how safe the #AirQuality in a space is, and lower or raise my cautions accordingly. (Details: https://www.harihareswara.net/posts/2023/my-current-covid-risk-approach/#ventilation ) Super useful.

I use and like the #Aranet4 #CO2 monitor. The #Aranet 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.
