So what makes you think you need to replace a smoke detector every 5
years? I had units in my house that lasted over 20 years.


Likely a dusty environment.


You mean *not* a dusty environment? These were AC units and most likely
died from a power surge. This house is in the boonies where voltage
surges are more common because of the long reaches.

Aren't most houses about the same level of dust? Being upside down on
the ceiling helps keep the crap out. My PCs pick up tons more dust.


On the other hand, I have not seen a CO2 detector for near the price of
a smoke detector. Are they really so inexpensive?


You mean CO detector.


Yes, of course.

My detector rolled over yesterday; full of dust and crap.

In Lowes I found battery powered, stand alone CO and smoke detectors
starting out at about $20, battery powered, stand alone combo CO/smoke
detectors starting at about $50.

High end, network enabled models for a bit more, hardwired dumb models
a bit less.


I have always been able to find battery powered smoke detectors for $10.
Walmart, Lowes, Home Depot...
