A home’s safety system is not complete without smoke detectors. They sound an alarm if smoke or fire is detected, allowing people inside more time to get out safely.
Smoke detectors save lives, but many people don’t realize they have a finite lifespan and should be replaced at regular intervals. We’ll go through how long smoke detectors typically last and compare several popular models.
Average Lifespan of a Smoke Detector
Experts agree that smoke detectors typically last for ten years. Following this period, the smoke detector’s sensors may begin to deteriorate, making it less effective or even useless. This is why it’s so important to replace your smoke detectors every ten years to make sure they keep working.
You may need to replace your smoke alarm sooner if it also detects carbon monoxide (CO). Most CO detectors have a warranty of five to seven years, according to Consumer Reports, so they may not be as long-lasting as regular smoke detectors. That’s why it’s so important to read the fine print of your device’s warranty before making any assumptions about how long it will last you.
Brand Comparison of Smoke Detectors
There are a wide variety of smoke alarms on the market, each with its own set of characteristics and expected lifespan. Here is a look at the typical lifespans of various widely available smoke alarm brands:
| Brand | Average Lifespan |
|---|---|
| Kidde | 10 years |
| First Alert | 10 years |
| Nest | 10 years |
| BRK Electronics | 10 years |
| Honeywell | 10 years |
| Ei Electronics | 10 years |
| Firex | 10 years |
| X-Sense | 10 years |
The table shows that smoke detectors typically last for ten years across all brands. There isn’t much of a difference in lifetime between brands, so customers can choose their favorite depending on features like smartphone connectivity or voice alarms.
It is important to check the manufacturer’s specifications before making a purchase because different brands have varying expected lifespans.
