Discovered with my new Aranet CO2 meter that our bedroom is 1800-2000 ppm at night 😫. No wonder I often wake up fatigued. Can’t have door open because cats disrupt sleep and can’t have windows open because cold and street noise. Daytime is okay (<1200 indoors) but not ideal (<1000). Gotta investigate hvac

Does your door have a gap at the bottom? 1-2" gap would help. Keep in mind: Even if you pump fresh air in, if it has no where to return then the pressure will build until the push does nothing. So need air in *and* air out. Otherwise also look at ERV/HRV, there's standalone units that can be done for one room.

If you have more than one bedroom, could try sleeping in separate rooms. Half the co2 production. :)
