This may be the most important article I’ve written for Trustworthy Home Advice. I had a discussion with my best friend’s son just yesterday who relayed a frightening story. He mentioned that he had heater problems which caused a carbon monoxide leak in his home. Fortunately, he had Carbon Monoxide Detectors in place and they went off alerting him to him to the problem. These monitors probably saved his, his wife’s and their dogs life. Mike G, thanks for sharing your story yesterday an inspiring today’s article.
I’m sure everyone reading this article will say, yah, we know about the dangers of Carbon Monoxide in the home. According to the National Institute of Standards and Technology (NIST), smoke alarms are now installed in 96% of all U.S. homes, which is great. However, the same data does not directly translate to CO detectors. If it were true (and its not) that only 4% of the 143.8 million U.S. Homes did not have CO Detectors like they do smoke detectors, that would mean that nearly 6 million homes are still unprotected from CO poisoning. So, if only one person reads this post and takes a few preventative actions, most importantly installing a CO detector and saves the lives of their family, it’s well worth another iteration on this topic.
The Invisible Killer
Carbon monoxide (CO) is a silent predator in the modern home, colorless and odorless, making its detection without the aid of technology impossible. The necessity of a carbon monoxide detector stems from its ability to save lives by alerting homeowners to the presence of CO, which can emanate from any fuel-burning appliance. Whether it’s a malfunctioning furnace, a blocked chimney, or even a car left running in an attached garage, the sources of CO are numerous and common in households. The best carbon monoxide detector acts as an essential line of defense, providing early warning of CO buildup, thus preventing potential poisoning incidents that can lead to serious health issues or even fatalities.

How to Choose the Best Carbon Monoxide Detector
Selecting the best carbon monoxide detector involves understanding the key features that contribute to its effectiveness. We’ve done this for you, but let me describe the most important considerations.
Firstly, the sensitivity of the detector to CO levels is paramount. A device equipped with an electrochemical sensor is considered the gold standard for CO detection due to its accuracy over time. Power source options also play a critical role; detectors can be battery-operated, plug-in with battery backup, or hardwired with battery backup, offering flexibility in installation and ensuring functionality during power outages. Additionally, features such as digital displays for CO concentration, peak level memory, and end-of-life alerts enhance the usability and maintenance of the detector. When choosing a CO detector, it’s also important to look for models that meet safety standards, such as those certified by Underwriters Laboratories (UL), to ensure the device’s reliability and performance.

Installation Tips for DIY’ers
Installing a carbon monoxide detector is a straightforward process that can significantly impact your home’s safety. Key considerations include choosing locations near sleeping areas to ensure alarms are heard during the night and avoiding placement near fuel-burning appliances to prevent false alarms. Wall-mounted or ceiling installations are common, with at least one detector on each level of the home, including the basement. Testing the detector monthly and replacing batteries annually (or as needed) are crucial maintenance steps to ensure optimal performance.
Maintenance and Testing Your Carbon Monoxide Detector
Regular maintenance and testing are vital to ensure your carbon monoxide detector functions correctly. This includes familiarizing yourself with the device’s test function, usually a button on the detector that, when pressed, verifies the alarm and battery operation. Replacing the detector according to the manufacturer’s recommended timeline, typically every 5-7 years, is also essential, as sensors can degrade over time. Keeping a maintenance log can help track testing and battery replacement, ensuring your device remains in good working order.
