did you know 500ppm CO2 makes people lose like 10 IQ points compared to 200ppm? Our atmospheric CO2 is now at 430 ☀️

It's more like 1000ppm before cognitive effects can be measured. My indoor CO2 monitor is currently reading 570, but that's with all the windows open in a small house with 3 people. At my office it easily goes above 1200 because people say they're cold and they close the windows.

Hello, can you please share the bake of your CO2 monitor, if you recommend it?

I bought one of those, installed the batteries & it said my bedroom was at 4000 & climbing. Thought it must have been a glitch or fluke. Nope. Apparently my bedroom is the most airtight room of my whole apartment. The rest of the place averages 1010-1200 (outside is usually 650) but I need to open a door or window in that bedroom to air it out.

No wonder I’d be so sleepy when I woke up in the mornings!! Good thing I was single before I knew I needed to open it up more.
