How and Where to Install a Carbon Monoxide Detector

Carbon monoxide detectors are an essential part of keeping you and your family safe in a home or apartment. Learn how and where to install carbon monoxide detectors correctly to make sure you stay safe.

Installing a carbon monoxide detector isn't as easy as just attaching it to the wall. Pay special attention to locations and living areas. Learn more below.

Location Is Key

Best Practices for Carbon Monoxide Detector Installation

  • Make sure you have at least one carbon monoxide detector on each level of your home, including the basement.
  • Locate carbon monoxide detectors near bedrooms – close enough so that they'll wake you up if they go off in the middle of the night.
  • Mount detectors on the wall at least a couple feet below your ceiling or even lower. Carbon monoxide often won't rise all the way up to the ceiling (like smoke does) until the concentration of the gas is at a critically dangerous level. Additionally, some carbon monoxide detectors have digital readouts – mount those kinds of detectors at eye level so you can read them. If you have pets or curious children, you'll need to find somewhere the detector won't be bothered.
  • The detecting mechanisms in carbon monoxide detectors need to stay at stable temperatures and humidities to work properly. Keep them out of direct sunlight and away from fixtures that generate heat (appliances, lights, radiators, etc.) and out of overly humid areas (bathrooms, laundry rooms, etc.). Keep in mind air flow, too: Don't mount carbon monoxide detectors by windows that are often opened or in dead air spaces.
  • Don't cover the detectors. Keep them mounted out in the open and away from curtains, furniture or shelves that could potentially block them or interfere with normal air flow to the sensors.
  • If your house has an attached garage, make sure you have a carbon monoxide detector mounted inside the house within 10 feet of the door to the garage. A running car could very easily elevate levels of carbon monoxide in the home.
  • Make your carbon monoxide detectors easy to test. Put them in areas where you can easily reach the detectors and check them every six months or so and get in the habit of replacing them when the manufacturer recommends it (most carbon monoxide detectors are good for about five years or so).

By following these simple steps and giving some thought to where you'll be placing your carbon monoxide detectors, you can make sure you and your family remains safe from this silent killer.
