I've been reading about Smoke/CO Detectors and stumbled upon a well written paper comparing smoke detector technology. There are at least two (2) common technologies call Ionization and Photoelectric. I suppose some of us might think that for the most part, a smoke detector is a smoke detector. Reading the following study helped me to understand the pro's and con's of these two (2) technologies.
Photoelectric vs Ionization Smoke Alarms - Deadly Differences (http://www.propertyevaluation.net/Photoelectric%20vs%20Ionization%20Smoke%20Alarms%20-%20Deadly%20Differences.html)
I hope this information is helpful to others.

Actually, Smoke/CO detectors (carbon
monoxide). CO2 is carbon
dioxide ;)
So that I actually add something - it's important to note that smoke, CO, and LP detectors all have a finite lifespan, generally 5-7 years for CO and LP and 7-10 for smoke. If you have had your LD 7 years or longer and haven't replaced them, please do so. If your LD is more than 7 years old and you haven't changed them yourself, look at the backs for the expiration date.
When in doubt, change them out! :D

Oops ... I stand corrected. Thank you Michelle.
