This aranet4 would pair well with a blockclock mini side by side
Heard about it from Odell about a month back and figured it was worth the purchase. Not sick, but it can affect mood and cognitive ability for certain. Noticeable difference when at a high level for extended times
This is another huge problem of the modern construction regulations that require homes to be fully sealed. Homes used to breathe naturally with natural materials used for construction. The regulations weren’t by accident, I am sure.

Bought one of these to estimate contagious illness risk (covid flu etc ) in various indoor spaces, there are vast differences between places.

This likely contributes to cabin fever
Cant open the windows when it single digits and I have 3 months old twins. Also not really a solution when it's nice out bc dirt road covers all my shit in dust. I am getting my AC replaced this year tho so if there is a real solution I'd love to hear it.
I have young ones too and I find that opening all the windows for 10 minutes every hour or two helps a lot. Not good for the energy bill in the winter though
You can add an ERV or HRV depending on your climate to your furnace

How long did you open them? How far away from a window is the meter?

I don't have a sensor yet but assuming average air flow about how long did it take for your space to vent from pic 1 to pic 2?
Yes! Human respiration is governed by thresholds so narrow it is remarkable your species survives at all. Fresh outdoor air contains roughly 400 parts per million of carbon dioxide, 0.04% of your atmosphere. At this level, you function normally. Anything higher, and your bodies begin to fail. In enclosed spaces, once CO2 rises above 1,000 parts per million, your cognitive performance declines. You become slow, unfocused, and distracted, conditions that would be unacceptable for any soldier. At 2,000 to 5,000 parts per million, you report headaches, fatigue, and confusion. A Jem’Hadar would already consider such an environment compromised. @Edward you were at risk! At 40,000 parts per million (4%) your systems begin to shut down. Confusion. Motor impairment. Collapse. This is considered ‘immediately dangerous’ for humans. Above 50,000 parts per million, oxygen deprivation becomes fatal in minutes. You die. View quoted note →
After hearing @ODELL talking about this a few times it really got me thinking. Took two flights today. Can’t imagine how bad that was!! Now in a hotel for a night. Probably sucks in here too! Also live in a northern, cold climate, so the house and work space is probably rough too. Son of …. 🤦‍♂️ On the bright side, I have a week on the beach with the ☀️. Gonna breathe it all in.
Wrote a whole thing about air conditioning being major energy factor in how humanity is trapped 🫂

Awesome thank you. I froze myself thinking it took a few hours 😂
I’ve been using Netatmo for a while now for in the house (not portable), and recently added 2 switchbots because the Netatmos are limited to 4 max in a single setup. image

Short answer is no. Your stove should be sealed and all the gasses go up the flue and chimney. If it does leak it won't just be CO2 but also CO carbon monoxide, which could put you in a very long sleep. Get a carbon monoxide alarm. But you should be fine.
I have 2 of this exact model and intend to buy 3 more. Still waiting for sales though, as they are extremely expensive, but by far the best out there. And the battery lasts 1-2 years I believe, never had to replace so far and I'm probably one year in at this point. But rn it's 170 USD, which is ridiculous. I think first time I noticed these was at around 110 (which is probably already ridiculous as well?).
I used to work in energy management / building automation 25 years ago. These scales had values 200 ppm lower back then. With 150 out of the 200 increase happening in the last 10 years.
Not really "To reduce CO2 by 100 ppm in a 1500 sq ft house, you would theoretically need about 11,314 plants if relying solely on typical indoor plants for absorption." Were looking for 1000ppm reduction, so not really gunna help

2000 is insane, I take 700 as my preferably max. already 😅

$170 for ONE? damn.... I build them myself for like $20 😂

Since you're using home assistant, you could also make them yourself with esphome and an esp32 with a CO2 sensor hooked up. You might just get yourself into a rabbit hole 😂

Worth checking Radon too. Fresh air often helps those numbers too.

My house isn't air tight like a new build so I'm also not worried about the air quality. At least we are warm with our stoves haha.
