I have a CO² sensor. When I sleep with the door shut, the CO² climbs up to and levels out at >1800 ppm.
I have a noticable headache the following day when I do this. I've tested it for nine days and now I've got a doorstop which prevents me from closing the door completely by accident or with drafts
Mine goes up to 2850 or so, even when I air out the room in the evening down to 430 or so.
But luckily no headache for me. I can't handle having the door open, I'm the last flatmate to get up in the morning.
Brew vats of algae in your room. Creates a ton of oxygen and is really easy to care for.
That's the most engineer ass answer I've ever seen.
High Co2? Algae can solve that. How much... Well a vat should do, better make it two just in case.
"Why yes, I do keep vats of algae in my bedroom why do you ask?"
It's my emotional support vat of algae. I keep it in my bed.
There was a video from a guy that tested that. It didn't go as well as he hoped.
If I am remembering the same video, he had like 4 five gallon containers. You can hardly call that a vat...
And you're just going to trust us to find the video ourselves?
Don't worry, you got this. I believe in you.
What kind of algae? I want to grow a vat of it. Assuming it's a fresh water algae.
That is wild.
Well there's another sensor to add to my wish list!
Although, we have a lot of HVAC flow into the bedroom so maybe the difference wouldn't be huge.
Get a Snake plant. They create a lot of Oxygen and easy to take care of.
Open the window.
Get better airflow in your room through ventilation.
Wear an o2 mask
Look for the largest air bubbles:
