Carbon monoxide detector where to place
Place carbon monoxide (CO) detectors on every level, near bedrooms (within 15 ft of doors), and outside the garage, typically on a wall about 5 feet high or on the ceiling, ensuring they are loud enough to wake you and away from cooking appliances and humid areas to avoid false alarms. CO mixes with air but also rises with warm air, so mid-level placement or on the ceiling works best to catch it at breathing height.
