A family emergency means I’m flying today for the first time since 2019. Fortunately I’ve got my N95 to reduce my inhaled dose as much as possible + my CO2 meter to gauge air.
Short 🧵 to occupy me while on a layover.
The CO2 was nicely & low in the Shreveport, LA airport (1/x)

2/ On this tiny United commuter flight, 45 minute flight time from Shreveport to Houston, no one with N95 masks. Maybe 2 w/ surgical masks.
Boarding & taxi process, the #AirplaneCO2 briefly peaked at 1600 ppm, but mostly in 1100 range. Obviously higher than ideal, but not bad.

3/ Cruising (if you call it that for just a few minutes) was still in the 1000 - 1200 ppm range. At that upper level, roughly 2% of the air is likely rebreathed from others on board. But the ventilation is also filtering resp. particles from background air relatively frequently.
Yeesh, NOT a plane I would like to be on! That's ~8+% rebreathed air being swapped between plane-mates. A good reason to make sure to wear a very good, tight-fitting mask (e.g. N95 or quality elastomeric respirator), especially for boarding, taxi, etc. #AirplaneCO2 #COVIDCO2
(This also assumes sensor wasn't unduly influenced by immediate breath of CO2 out of @HaywardScoreCEO holding the sensor. In that case, it doesn't fairly represent the mixing of CO2 into the whole volume, because you exhale at ~40,000 ppm.)
A very interesting paper of CO2 concentrations on airplanes h/t @WBahnfleth. Data from 52 commercial plane flights: ventilation rate is usually highest during cruising (low CO2); worst when boarding, taxi, etc.
