How often do we need to replace smoke and co2 detectors in homes?

Smoke and CO detectors are essential safety devices in homes, and it’s important to ensure that they are functioning properly. As a rule of thumb, smoke detectors should be replaced every ten years, and CO detectors should be replaced every five to seven years.

However, it’s important to note that these are just general guidelines, and the specific recommendations may vary depending on the manufacturer’s instructions and local regulations. It’s always a good idea to refer to the user manual or contact the manufacturer for specific recommendations on when to replace your detectors.

Additionally, it’s important to test your smoke and CO detectors regularly and replace the batteries at least once a year. If the detector is malfunctioning or giving false alarms, it’s important to replace it immediately, regardless of its age.
