I would like to ventilate my bedroom because air quality monitors show CO2 levels rising above 2000ppm every night.
I have two windows in the room, both with blackout blinds, but I prefer not to open them at night because they are street-facing and sun-facing and bring in noise and light. I also can't open the bedroom door for roughly the same reasons: light and sound from the rest of the house.
My question is, how can I ventilate the room given these constraints?
Two solutions I have thought of so far:
- Use window fans. This would work, except it would also probably bring in both light and noise.
- Use a fan + some sort of duct to force air under the door. According to the article here, from what I understand, door undercuts can work. I am just not sure what to look for to begin to build or install something like a door undercut fan duct.
Any other suggestions are welcome as well.
