The correct timing is stated by the manufacturer for the specific product, often on the label, in the manual, or in the app for a connected device. Most CO detectors need replacement after 5 to 10 years from the <strong>manufacture date</strong> — not the date you installed it.</p> <p>Do not troubleshoot a loud repeating CO alarm as an age question. Get everyone outside to fresh air, call emergency services from outside, and stay out until responders say it is safe.
