if I travel and expect to be working I now bring a CO2 meter

Just open the door

You know what also impacts my decision making ability? Freezing my ass off because people are opening all the windows every five minutes.

Wow, what a revelation. People rediscover basic things in life :D.

I can feel the AI in the text.

Aranet detectors are superb, and – best of all! – made in Latvia.

if price is no object get the AirGradient PM2.5+CO2

but Ikea now makes the most affordable PM2.5+CO2 sensor, at $35 a no-brainer

in there is a very nice/expensive Sensirion SN63C sensor that costs nearly as much as the Ikea itself

unfortunately Ikea requires Matter network not plain wifi for communication so I've been looking for a cheap Matter hub or DIY SPR

Imagine if we applied this logic to climate change?

open a window, wait, ok, ok, turn up the , wait, no, ummm, hmmmmm re, re, no forget that, hmmm anyway, as a person with a strong interest in civil engineering, systems, and the subset of air handling, I can say that there has long been disenting arguments about how things are built,that have been ignored due to cost, which are large in terms of internal volumes required, and the intractable issues around, noise, filtration, heating/cooling and maintenance. And as the climate warms, and in many areas pollution increases , the inadequate methods used to "calculate" requirements, get further from real world needs. You could try throwing a desk through a window, but as that is one of the things the planners and engineers have antisipated, it will prove to be surprisingly difficult.

Yet another reason to have meetings while walking outside: air quality and a natural limit on time, and the mental benefits that come from movement.
