Co2 Detector

Ive had the same CO2 detector for over 10 years. Do they
to? I was told that I should replace it with newer technology of the detector.

Smoke / CO detectors have a lifespan of 7 years. This is 7 years from the date of manufacture, not 7 years from the date of first use. I suggest to replace them after every 5 years or more.

In my state, there is a code of fire safety to replace them every ten years in commercial and industrial. I replace mine every 6 years. My family is worth it.

yes, they go bad over time it is generally referred when to replace after so many years, but do not know how
