I was curious about the levels of CO2 in my room so I went and bought a sensor for my bedroom. I was somewhat appalled when I woke up this morning with heavy eyelids to see the concentration at 1700 ppm.
Guess I have to leave my door open now.

Is your room really small? 1700 seems really high for just breathing. Unless the sensor is like right next to your mouth.
I have a somewhat small room. The sensor was mounted on an opposite wall so I’m not sure what could be causing this high reading besides me and my CPAP machine. I think it might be coming from the sump pump that’s a few floors below my room. I calibrated it last night outside and it set itself to ~400ppm. As I’m writing this the room has mostly settled back down to 770ppm. To be fair though, my room regularly does feel muggy and hard to concentrate in (less so with a door open), so I’m not entirely doubting this reading.
It seems about right to me. Fortunately just a little ventilation goes a long way. You really only need a little fresh air per person to keep levels low. You can go crazy with online calculators to determine an exact CFM number for a given number of people in a room of a certain size, or you can just experiment and watch the sensor.
