When Should I Replace My Carbon Monoxide Detection Device?

Headaches are one symptom of carbon monoxide poisoning

At the Manufacturer's Suggested Time

Each brand of carbon monoxide detector comes with instructions. These include information on when to replace the device. Each brand's lifespan differs. The New York City Department of Housing Preservation and Development recommends following the manufacturer's instructions.

About Every Six Years

According to the Official Fire Department of New York City, all carbon monoxide detectors should be replaced once every five to seven years, no matter what the brand. It also notes that cleaning dust off the detectors and not painting over them will help them function for five to seven years.

Bottom Line

To be on the safe side, carbon monoxide gas detectors should be replaced no later than every five years. Test the batteries every month and replace them after a year.
