What is the primary purpose of a carbon monoxide detector?

The primary purpose of a carbon monoxide detector is to alert occupants to the presence of carbon monoxide. Carbon monoxide (CO) is a colorless, odorless gas that can be produced by burning fossil fuels and is a significant health hazard when accumulated indoors. A CO detector continuously monitors the air within a home or building for elevated levels of this toxic gas. When the concentration of carbon monoxide reaches a certain threshold, the detector emits an alarm, warning occupants to evacuate and address the source of the gas, which is critical for preventing poisoning or even fatalities.

While measuring overall air quality, improving ventilation, and testing humidity levels are all important aspects of indoor air quality management, they do not pertain specifically to carbon monoxide detection. A detector's sole function is to monitor for CO and ensure that individuals are alerted in a timely manner to any hazardous conditions related to CO exposure.
