Does carbon monoxide stay high or low in a room?
Because carbon monoxide is slightly lighter than air, some recommend that you place it on the ceiling or at least 5 feet from the floor. However, some studies show carbon monoxide doesn't settle at the floor, float in the middle, or rise to the top; rather, it disperses at an equal concentration throughout the room.
How much heavier is carbon monoxide than air?
Carbon monoxide is slightly less dense than air. It is measured with exactly 28 molar mass while the average air has 28.8 molar mass. The mass between the two is not too far which makes carbon monoxide evenly scattered with air particles.
Where should carbon monoxide detectors be placed in a home?
The International Association of Fire Chiefs recommends a carbon monoxide detector on every floor of your home, including the basement. A detector should be located within 10 feet of each bedroom door and there should be one near or over any attached garage. Each detector should be replaced every five to six years.

Do smoke detectors detect carbon monoxide?
For smoke detectors, we test response time to both flaming fires and smoldering, smoky fires. We've found that not all detectors can adequately detect both fire types. For carbon monoxide detectors, we test them against low CO levels (at 100 parts per million) and high CO levels (at 400 ppm).
Does carbon monoxide dissipate quickly?
Fact: CO in an enclosed area will not dissipate quickly. It has the same weight as the air and mixes in with the oxygen we breathe.

This means that if you are breathing fresh, carbon monoxide-free air, it will take five hours to get half the carbon monoxide out of your system.
