Clean Air For Class
@CA4Class
A campaign group urging the Scot Gov to place CO2 monitors and HEPA air purifiers in every classroom and count classmates as close contacts. Sign the petition!
@Sisu56693590 Lots of resources to read up on CO2 sensing. Short video overview: news.yahoo.com/co-2-monitors-… Article: washingtonpost.com/health/2021/02… Simulations: english.elpais.com/usa/2021-03-29… Re-breathed fraction: twitter.com/CorsIAQ/status… Handy graphic: twitter.com/RichardBarrow/…
2/ RF can be calculated as RF = (CO2in - CO2out)/CO2breath Here CO2in is CO2 concentration in the indoor space, CO2out is the outdoor CO2 concentration, and CO2breath is the typical CO2 concentration on human breath (around 36,000 to 38,000 ppm) w/ some variation by diet, etc.
1/ CO2 and COVID transmission Our paper (former preprint) is now published after peer-review in Environ. Sci. Tech. Letters: pubs.acs.org/doi/10.1021/ac…
@mdc_martinus ...and people can share them now 😉 covid-co2-tracker.herokuapp.com/home
1/ A 🧵 on some #CO2 measurements in my home, car, school *AND* details/instruction on how to use dry ice for DIY estimate of #ventilation rates at your home or as a school project. Highlights in thread & gathered together in the linked doc 👇. #COVIDCO2 docs.google.com/presentation/d…
Great to see #covidCO2 mentioned in The New York Times! It began as an idea, 14 months ago, and it is slowly growing into an international movement of "guerilla air-monitoring". We better keep doing it if we want to incite governments to do something about #SafeIndoorAir!
Sending a #CO2 monitor with a kid to school is one way to get a rough idea of the ventilation quality. Curious to hear your simple or sneaky strategies of how you've sent a #COVIDCO2 monitor. (DIY innovations aren't just for people making a #CorsiRosenthalBox for filtration. 😉)
An opportunity for an important, interesting story for some national & local journalists. It won't be hard to ask around Twitter for parents who have been blocked from sending CO2 monitors after their kids recorded unhealthy CO2 (meaning poor ventilation) 👇. #COVIDCO2 #SchoolCO2
