The best carbon monoxide detector is a simple device that alerts residents with a loud 85-decibel alarm. You should have one in every room of your home, near all sleeping areas and a garage. Carbon monoxide is odorless and tasteless, so it can be very dangerous. For peace of mind, make sure you choose a model that includes a battery backup in case of a power outage and a test button. Some detectors also offer a digital display, which can show peak CO levels in parts per million and help you determine the source of the problem.
Some models even connect to other hardwired devices and provide you with notifications and alerts on your phone. If you’re looking for a plug-in carbon monoxide detector, look for one with dual smoke sensors (ionization and photoelectric) and microprocessor technology to cut down on false alarms.
You should also check a carbon monoxide detector’s warranty. According to Koether, many monitors have seven to 10 year warranties. If the unit is reaching its end of life, it will chirp to indicate that you need to replace it.
