Carbon Monoxide Alarms

The leading cause of accidental poisoning deaths in North America, Carbon Monoxide (CO) is odorless, tasteless and invisible – it's a silent killer. The only safe way to know if carbon monoxide is present is to install carbon monoxide detectors (alarms) on every level of your home and in sleeping areas. Kidde has been making CO alarms with electrochemical sensing technology for years.
