How Often Should You Replace Your Carbon Monoxide Detector?

Check Your Model

There are a variety of carbon monoxide, or CO, detectors available on the market in the three main types: battery-operated, plug-in and wired. The lifespan varies from model to model. Earlier designs had a lifespan of two years, while newer models have a lifespan of up to seven years. It is essential to check with the manufacturer for the lifespan of your individual model.

Test Your Detector Regularly

The National Fire Protection Association recommends testing carbon monoxide detectors every month. Newer models have a signal that indicates the need to be replaced. According to manufacturer's instructions, you should get a new detector every two to 10 years, depending on the model.

Bottom Line

CO fumes are extremely poisonous.

Carbon monoxide poisoning is known as the silent killer due to its odorless, colorless and tasteless fumes. Check your manufacturer's instructions carefully, and replace your CO detector when your particular model's lifespan has ended.
