@knizer this article's got a bunch of good data on #CO2Monitors; recommendations are at the end and are more or less the same units I would consider trustworthy:

There's a really good sale on that particular Inkbird right now, too

It’s genuinely not controversial to recognise that CO2 monitoring absolutely can have utility, but that it’s utility is context dependent.
It can falsely reassure in underventilated spaces with short duration or low density occupancy, or it can falsely alarm in spaces where non-ventilation interventions are in place (eg filtration).

It does say CO2 800ppm
Is indicative of good ventilation
But it also says
CO2>1500ppm Poor
&
To Take action at CO2 >1500ppm
Why 🤷🏽

When the purpose of buildg regs are to ensure
New builds &refurbished buildgs
Must meet MINIMUM STANDARD
Now
CO2<800ppm

Just came across this French Air-Score for indoor venues from @nousaerons https://nousaerons.fr/aero-score/

And several libraries in Canada are loaning #CO2Monitors ! Ottawa had 28 sensors to loan, and 2 days ago more than 600 were on hold. Community support for #IAQ. Hoping US libraries start catching on...

I anticipate the institutional structure will implicitly (intentionally?) discourage holding organizations accountable when individuals have access to their own #IAQ data & demand #HealthyAir

Prove me wrong 😊 I'm good with that! My next rant will be about the need for AFFORDABLE #CO2Monitors and more US #library lending programs. Yay #Canada!

And I'm working on just such a program, with invaluable support of @CAVI_CO2@twitter.com. More soon

when #IAQ is not treated like #waterQuality, I need tools. "Consequently, they [#CO2 rebreathed data] may not be highly accurate predictors of absolute risk." ASHRAE, last sentence - https://www.ashrae.org/file%20library/about/position%20documents/pd_indoorcarbondioxide_2022.pdf

That's NOT the standard for this issue. We need all risk mitigation (Swiss cheese model, anyone?), and reliable #CO2Monitors can be a valuable tool!

@marinavance Greetings. I'm working on a proposal for local #library loaning of #CO2monitors and am a little bummed to discover today that #EPA's "Air Sensor Loan Programs" are only for PM, not #CO2. Pollution is certainly a vital concern, but with the #CovidIsNotOver epidemic, I believe the indoor proxy for #airborne pathogens is as, or more, vital for public health right now. Your thoughts? TIA
