Availability of Carbon Monoxide Detectors

Home carbon monoxide detectors can be purchased at any hardware store and range in price from about $10 to $300. Make sure that the device you purchase is certified by Underwriters' Laboratories (UL). Install it and maintain it according to the manufacturer's instructions.

There are several types of detectors, with different features. Several models plug into home AC outlets; others are hard-wired or battery powered. Some carbon monoxide detectors talk; others have a digital display. Many have a combination sensor/battery that must be changed about every two years. Carbon monoxide detectors usually use a chemical reaction sensor, which will deteriorate after a couple of years and must be changed.
