Replace smoke alarms after how many years?

Explanation:
Ten years is the recommended interval for replacing smoke alarms. The sensing components and overall electronics wear out over time, and reliability declines as the unit ages. Replacing the alarm after a decade helps ensure it will detect smoke promptly when needed, rather than risking a sensor that may fail to alert you. If your alarm has a sealed 10-year battery, you still replace the entire unit at about the 10-year mark. In practice, you should test alarms monthly and follow the manufacturer’s guidance on replacement dates, so you stay protected.
