Winter is the deadliest time for carbon monoxide poisoning. Carbon monoxide (CO) is an odorless, colorless, tasteless gas that kills more than 400 Americans every year, according to the Centers for Disease Control and Prevention.

After seven years, the alarms will begin to chirp, letting you know a replacement is needed.
More information about carbon monoxide and CO alarms is available in the Carbon Monoxide Alarm Guide.
