Tips: How often should smoke detectors be replaced?

Smoke detectors should generally be replaced every 10 years. The replacement timeline can vary depending on the manufacturer’s recommendations and the specific type of smoke detector (ionization, photoelectric, or combination). It’s important to check the manufacturer’s instructions for the specific model to determine the exact replacement period. This standalone smoke detector will last for ten years.

Additionally, it’s a good practice to test smoke detectors monthly to ensure they are functioning correctly and to replace the batteries annually, or when the low battery signal is indicated. If a smoke detector is damaged or fails to pass the monthly test, it should be replaced immediately.
