Documenting Problems That Were Difficult To Find The Answer To

Winston Carbon Monoxide Detector Fault

I bought a Winston carbon monoxide detector after being advised I should have one in my home.

Unfortunately it developed a fault after several months where it started to display a minimum of 28-32ppm and I became worried I had a problem in the home! But moving it around rooms or outside into the fresh air wouldn’t bring the number down – nor would powering the unit off and back on.

To ensure it was the unit at fault and not the air I purchased a Fireangel carbon monoxide detector.

When placed side-by-side the readings were thus:

Winston detector reads 34 while Fireangel reads 0

Winston detector reads 34 while Fireangel reads 0

Was the Fireangel carbon monoxide at fault by not detecting anything? I soon found out when I parked my misfiring car with the exhaust facing the home (not intentional, just so happened it seemed to affect the air inside the home). The side-by-side readings were thus (at 19:33 on the day in question):

Winston detector reads 53 while Fireangel reads 51

Winston detector reads 53 while Fireangel reads 51

So it seems that both detected an elevated amount of carbon monoxide in the air. But over the course of tens of minutes the numbers began to drop in the following sequence (at 19:35 on the day in question):

Winston detector reads 52 while Fireangel reads 44

Winston detector reads 52 while Fireangel reads 44

Then (at 19:39 on the day in question)…

Winston detector reads 47 while Fireangel reads 36

Winston detector reads 47 while Fireangel reads 36

Then (at 20:12 on the day in question)…

Winston detector reads 36 while Fireangel reads 12

Winston detector reads 36 while Fireangel reads 12

Finally (at 20:50 on the day in question)…

Winston detector reads 34 while Fireangel reads 0

Winston detector reads 34 while Fireangel reads 0

I demanded a refund for the faulty Winston unit because it concerned me that a unit should be falsely warning an unhealthy situation when, in fact, there was no discernible carbon monoxide present in the atmosphere.
