In flight to #AAAR to present a poster w/ my kids “Making Aerosol Precautions for COVID-19 More Easily Accessible and Affordable to Everyone” tysm @HuffmanLabDU. On flight ✈️ I brought tools (CO2, 0.3 μm OPC) to see what’s up here at 30,000 feet 👣 (1/3) aaarabstracts.com/2022/view_abst… 
CO2 🧘♀️: compared to hair-raising reports of 2000+ ppm on other flights, CO2 has been relatively tame on jet bridge, while airplane ✈️ was on ground, and once in flight about 1000-1500 ppm. Still high relative to home 🏡 (800-1000 ppm) but not as high as I feared. (2/3)
0.3 μm particles⚡️ : much more interesting. After pilots 👩✈️🧑✈️ turned off seat belt sign, I ran a particle counter 💻 and it was ~10,000 per liter (typical for outdoor). An hour into flight it was ~300 which usually takes ~10 ACH at home. Inflight HEPA filtration at work! (3/3)
Having fun doing science experiments at 30,000 feet aboard the “clean room” environment on the airplane. The video shows 0.3 μm aerosol particle counts at ~300 per liter and then rising above ~800 within seconds of popping open a Coke can @adsquires @mikechenwriter @PlasticFull
