Don’t let buying a CO detector lull you into a false sense of security. Preventing CO from becoming a problem in your home is better than relying on an alarm.
When you shop for a CO detector, do some research on features and don’t select solely on the basis of cost. Non-governmental organizations such as Consumers Union (publisher of Consumer Reports), the American Gas Association, and Underwriters Laboratories (UL) can help you make an informed decision. Look for UL certification on any detector you purchase.
Carefully follow manufacturers’ instructions for its placement, use, and maintenance.
It is important for you to know that the technology of CO detectors is still developing, that there are several types on the market, and that they are not generally considered to be as reliable as the smoke detectors found in homes today. Some CO detectors have been laboratory-tested, and their performance varied. Some performed well, others failed to alarm even at very high CO levels, and still others alarmed even at very low levels that don’t pose any immediate health risk. And unlike a smoke detector, where you can easily confirm the cause of the alarm, CO is invisible and odorless, so it’s harder to tell if an alarm is false or a real emergency.
