Do carbon monoxide detectors expire?
Carbon monoxide (CO) detectors expire after 5 to 10 years of use. Most carbon monoxide detectors have an expiration date on the back of the sensor to let you know when it’s time to replace it. The detector will also start chirping two to five times every 30-60 seconds once it has expired.
How do I know if my carbon monoxide detector is worn out?
Check the back of your detector for either a build date or an expiration date. If there’s no date or your CO monitor is more than seven years old, replace it now. This label shows a manufacture date for the CO monitor. If you wonder if your carbon monoxide detectors are worn out, they probably are.
How do I know when to replace my CO detector?
CO (carbon monoxide) detectors usually wear out in 5-7 years. Replace them with a “fuel-cell electro-chemical” sensor type and with a “peak” level memory to alert you to the highest level of CO present. Check the back of your detector for either a build date or an expiration date.
When should I change the battery in my carbon monoxide detector?
If your alarm sounds every 30 seconds the battery may need to be changed, the detector should be replaced, or there’s a malfunction. Where should I install a carbon monoxide alarm?

How do I know if my carbon monoxide detector is still good?
1 beep every minute: This means that the detector has low batteries and you should replace them. 5 beeps every minute: This means your alarm has reached the end of its life and needs to be replaced with a new carbon monoxide alarm.
When should a carbon monoxide detector be replaced?
every seven to ten yearsIn accordance with the National Fire Protection Association (NFPA), Kidde recommends replacing smoke and heat alarms every ten years and replacing carbon monoxide and combination alarms every seven to ten years (depending on your model) to benefit from the latest technology upgrades.
How long is a carbon monoxide tester good for?
five to seven yearsHow Often Should I Replace my Carbon Monoxide Detectors? Typically, you should replace your detectors once every five to seven years, but there's a little more to it than that.
How long does a Kidde carbon monoxide detector last?
Kidde carbon monoxide alarms have a proven life of seven to ten years, depending on the model type. Important Note! Carbon monoxide alarms do not detect the presence of carbon monoxide when in end-of-life mode. Replace your carbon monoxide alarms before the end-of-life warning.
Why is my First Alert carbon monoxide detector beeping?
1 Beep Every Minute: Low Battery. It is time to replace the batteries in your carbon monoxide alarm. 5 Beeps Every Minute: End of Life. This chirp means it is time to replace your carbon monoxide alarm.
Do unused CO detectors expire?
Carbon monoxide detectors don't last forever and they do expire. Over time, the components inside the detector degrade. The average lifespan is seven years and you should try to replace yours every five years.
Why do carbon monoxide detectors expire?

Press the reset button and replace the 9 volt battery or 2 AA batteries (depending on the brand of carbon monoxide detector you have such as a Kidde or First Alert brand) to stop the beeping.
What do I do if my carbon monoxide detector is beeping?
While it's important to call 9-1-1 if your CO alarm is sounding continuously without stopping, a CO alarm that chirps every 30 seconds is not an emergency. It probably means your CO alarm has reached its end of life and should be replaced. CO alarms have a life expectancy of around seven years.
How do I stop my carbon monoxide alarm from beeping in the end of life?
Your detector may be reaching its end-of-life cycle, and may need to be replaced. Many carbon monoxide and smoke detectors come with a “Hush” feature, which will stop the beeping for 72 hours. To silence the beeping, press and hold the “Hush” or “Test” button.

What is the difference between a biomimetic and an electrochemical sensor?
Biomimetic sensor: When carbon monoxide is absorbed by a gel, it changes color and triggers an alarm. Metal oxide semiconductor: A silica chip lowers electrical resistance when CO is present and sounds an alarm. Electrochemical sensor: An alarm sounds when electrodes in a chemical solution sense a change in electrical currents from coming ...

What is Carbon Monoxide?
Often referred to as “the invisible killer,” carbon monoxide (CO) is a colorless, odorless gas produced when gasoline, propane, wood, charcoal or other fuels burn incompletely. A faulty furnace or hot water heater can quickly lead to high CO levels in a home.

Is a carbon monoxide detector more effective than a horn?
A voice warning is more effective than a horn at waking children. Since carbon monoxide is roughly the same weight as air, it neither rises toward the ceiling nor sinks to the floor. So detectors that don’t have a digital display can be mounted anywhere as long as they’re at least 15 in. below ceilings.
Does humidity affect carbon monoxide detectors?
There are other types of sensors on the market (metal oxide and gel cell) that offer longer life. But humidity and temperature changes can reduce their accuracy. When it comes to detecting carbon monoxide, we recommend accuracy over detector life span.
Methods by Which Carbon Monoxide Detectors Can Be Disposed Of
Place the carbon dioxide detector in a metal container, such as a tin can. Metal containers are great for disposing of carbon dioxide detectors because they are usually non-biodegradable. Also, they will decompose at the same rate as the metal. You can also use a steel can or steel bucket.
The Average Lifespan of Carbon Monoxide Detectors
In the United States, the average life span of a carbon monoxide detector is approximately 15 years. This means that unless the owner disposes of their carbon monoxide detector properly, there are many older models that will need to be thrown away or recycled when they run out of battery.
Why You Should Recycle Carbon Monoxide Detectors
1. CO detectors are hazardous and should be thrown away in a metal container or landfill. They are hazardous because they contain mercury, which is toxic to the human body.
How to Recycle Carbon Monoxide Detectors
When it comes to the disposal of carbon monoxide detectors, first try to find out whether your town or city offers a recycling program for these devices. If you can’t find a local program, then check with your trash company, county or state office. They may be able to offer assistance in finding a place to recycle CO detectors.
How does a carbon monoxide detector work?
How do carbon monoxide detectors work? When CO is detected, the carbon monoxide alarm’s sensor triggers an alarm to alert you. If you’re unsure if the alarm is working, test it by checking the wall outlet’s power or batteries. Why is my carbon monoxide detector beeping every 30 seconds?
