which CO detector?

0 votes
Hi Dariusz.

I came across your website today as I was reading up on CO detectors.  It is great and I'll certainly be back.  Good job!

After reading a bit, I'm having a hard time picking WHICH CO detector I should get.  Do you have any recommendations?  I am not able to get one that is hard wired.

I initially thought of getting one that is plugged into an outlet with a battery backup. It seems that may not be optimal because they should be placed higher up like a smoke detector.  Is this accurate?  I also saw some do not detect at a good ppm level, some are not UL rated, etc.  Based on my reading, I thought I should get one that has a digital display that shows the reading level rather than one the just gives an audible alarm if triggered. Do you agree with that or is it marketing hype?

If it is best to place in a similar place as a smoke detector, I thought it may make sense to get a combination smoke and CO detector.  After reading some reviews about combination smoke/CO detectors, I also saw some of the same issues with people indicating some are better than others.  It got a bit beyond my understanding talking about ionization and photoelectric detection.

So my question is, can you recommend your favorite 2 or 3 CO detectors and top 2 or 3 combination smoke and CO detectors?

Hi Nmize,
Thank you, I’m glad you find my articles helpful. 
The installation location (as far as positioning on the wall / ceiling) isn’t as crucial in their case as with the smoke detectors, except of course for the locations described in my article as the ones that should absolutely be not used for that purpose - http://checkthishouse.com/4822/where-to-install-carbon-monoxide-alarm-co-detector-locations.html
But if you’d like to use combination units you have to follow the installation guidelines that apply to smoke alarms - http://checkthishouse.com/4728/where-to-install-smoke-detector-smoke-alarm-placement.html . The 4“ from the wall and / or ceiling corners rule / requirement has been removed from the code. Types are briefly explained in this post - http://checkthishouse.com/537/smoke-detectors-is-your-life-worth-at-least-1000.html
Unfortunately I don’t have any favorite CO detectors so you need to do some research. I usually go to this website - http://www.consumersearch.com/carbon-monoxide-detectors or you can use http://www.consumerreports.org/cro/co-and-smoke-alarms.htm which requires paid subscription.
