Isn’t it a myth that CO sinks? People think it’s heavier than air, but it’s lighter by mass. Is there some other reason it would sink?

Definitely an often mentioned thing. The concern with CO is that it disperses evenly everywhere. So it doesn't really sink or rise just mixes.

Always grew up hearing that the detectors need to be low along the wall when it is actually recommended to be mid-wall or slightly below eye level. They'll really be effective placed anywhere in a room.

Not sure why it is perpetuated. I imagine the fact that outlets are lower to the floor and typically where a plug-in style would go reinforces this belief.

I got battery powered CO detectors so I could put them at eye level without running wires down walls. I guessed that maybe they were supposed to be at eye level because CO hovered at a certain level based on relative humidity in the room but it’s probably just that it’s where people are likely to breathe it in, yeah?… if it all just mixes.
