A carbon monoxide detector is one of the most important items to have in your home. Carbon monoxide (CO) cannot be smelled or seen and can have deadly effects within minutes, thus it in vital that your home is equipped with a CO detector.
Before recommending a detector, be sure to educate yourself on what type of detector to purchase. Do you know the differences between the biometric, semiconductor and electrochemical CO detectors?
Biometric CO Detector—This one has an internal gel cell that is made of synthetic hemoglobin that works to absorb the CO. It is crucial that the battery and sensory module be replaced every two to three years, but the detector itself should last approximately 10 years.
Semiconductor CO Detector— A semiconductor detector is a plug-in unit that is equipped with an electronic sensor. This model is a good choice for people who are looking for a device that requires minimal maintenance. Typically, this model lasts from 5 to 10 years.
Electrochemical CO Detector—An electrochemical detector works by responding differently to the varying levels of CO exposure. This device has a self-powered battery that does not need to be replaced and the detector usually lasts for at least 5 years.
Remember to also look for:
• Lighting Features—During an alarm, not only will the alarm go off but a light will also flash. Look for an alarm that has an easy-to-read light-emitting diode (LED).
• Power Supply Backup—In case of a power outage, you will want a backup feature.
• Newest Manufacturing Date—This will ensure you are purchasing the newest technology.
• Peak CO Memory—This feature will typically appear on higher-end models and is a display that remembers the highest levels of CO over a certain time period. The memory feature is useful for emergency personnel when trying to determine the severity of the CO problem.
