How often should smoke detectors typically be replaced?

Smoke detectors typically have a lifespan of about 10 years. This is because the sensors within the detectors can degrade over time, which may lead to a decreased ability to detect smoke effectively. Manufacturer guidelines and building codes generally recommend replacing smoke detectors every 10 years to ensure optimal functionality and safety in detecting fires. Choosing this time frame helps maintain the reliability of the device, aligning with the preventive safety measures that protect lives and property. Regular maintenance is important, but simply performing maintenance does not substitute for the necessity of replacing the unit when it reaches the end of its lifespan.
