How often should you check your carbon monoxide detector?

Do you really need to replace smoke detectors every 10 years?
Smoke alarm lifespans can vary, but according to the association, smoke alarms need to be replaced at least every 10 years. According to Carli, that lack of awareness means some U.S. homes may have smoke alarms that have passed their expiration dates, putting people at increased risk in the event of a home fire.
How do you test a smoke detector?
If you want to test a smoke detector, find the test button on the front or side of the unit. Push and hold the button for a few seconds to ensure the alarm sounds. If it doesn’t, you may need to replace the batteries or have an electrician check the wiring in the detector.
Why do smoke detectors only last 10 years?
It likely has to do with the lifetime of the hardware itself. Remember, there’s a circuit board and a light source, as well as a detector. Those don’t last forever. So the manufacturer certifies the device will work for only 10 years, and then (in some modern units) sets a hard sunset by using an unreplacable battery.
