However, your major concern is not only on your budget but it should be at how long you can operate CO gas detector in order to give continuous protection to your family safety.
CO gas detector lifespan differs from one brand to another brand. There are many reasons why each CO gas detector has different lifespan. Sensor type and manufacturing technology are among the major factors.
Factors Affecting CO Gas Detector Lifespan
As an electronic device, CO gas detector has certain lifespan. Even an exactly same CO gas detector will probably have different lifespan if they are installed in a different environment.
Even though a CO gas detector manufacturer claims that their CO gas detector lifespan is 5 years, it does not mean that it will stand as what they claim. There are some factors that you should pay attention to such as room temperature, concentration of dust in a room, direction to sunlight, humidity, distance from heat source and how it is maintained.
The key factor is you should follow installation guidance that you find in the manual. Try to install CO gas detector in a room that is closely to a recommended condition. Otherwise, its lifespan may be shorter than you expect.
CO Gas Detector Lifespan for Some Brands
For some people it may be hard enough to find the information about their CO gas detector lifespan. Sometimes, its manual does not mention this term clearly.
Here is CO gas detector lifespan information I got for several CO gas detector brands that you may have installed in your home.
Keep this information as you will require them sometime in the future.
First Alert CO615: not mentioned clearly, 7-years limited warranty
First Alert CO605: not mentioned clearly, 5-years limited warranty
First Alert CO400: not mentioned clearly, 5-years limited warranty
Kidde KN-COPP-B-LPM: 7 years
Kidde KN-COPP-3 Nighthawk: 7 years
Kidde KN-COSM-IB Hardwire: 7 years
What to Do
When you hear end-year life “chirp” from your CO gas detector, replace it immediately. Do not make a delay to replace the unit. It is very dangerous since there is no tool detecting carbon monoxide in your home. Replace it immediately when it achieves its lifespan.
