How often should smoke and carbon monoxide detectors be tested?

Testing smoke and carbon monoxide detectors monthly is recommended to ensure that these critical safety devices are functioning properly. Regular testing helps confirm that the alarms are operational and can alert occupants in case of a fire or the presence of carbon monoxide, both of which can be life-threatening situations. Monthly checks also allow for timely replacement of batteries as needed, which is essential for maintaining the effectiveness of the detectors.

While other frequencies for testing might seem reasonable, monthly testing aligns with safety guidelines set by various health and safety organizations. This frequency strikes a balance between being frequent enough to catch any malfunctions or low batteries, while not being so frequent that it becomes inconvenient for households to maintain.
