What action should be taken with smoke detectors that are over 10 years old?

Smoke detectors typically have a lifespan of about 10 years, after which their reliability can decrease significantly. As components degrade over time, the risk of failure in detecting smoke and fire increases. Therefore, when smoke detectors reach the age of 10 years, it is recommended that they be replaced rather than repaired or merely cleaned.

Replacing smoke detectors ensures that occupants are protected by devices that are still capable of functioning properly to detect smoke and alert individuals in the event of a fire. Regular replacement as part of a maintenance routine provides peace of mind and significantly enhances safety in residential and commercial settings.

Cleaning and battery replacement are important maintenance tasks but do not address the inherent aging of the smoke detector's technology and components. Repairing an outdated unit may not restore it to optimal function even if it appears physically sound. Thus, replacement is the prudent course of action when smoke detectors reach the 10-year mark.
