How many Carbon monoxide Detectors are required for a single family home ?
Asked by: Randy
For maximum protection, put one in each room where someone sleeps (or takes naps). Also put one in your furnace room and hot-water-tank room, if you can. (Especially where equipment is rather old)

Battery Operated Carbon Monoxide Detector is rated 4.5 out of 5 by 847.
Rated 5 out of 5 by from It actually got put to the test and worked! Well, since it's very difficult to review/test a carbon monoxide detector...I actually had a situation in my home and it worked just like it's supposed to. We were getting our carpets cleaned and the their van was in our garage with engine running. (of course garage door was open!) Over the duration of the cleaning, exhaust began entering our internal garage door into the house and this thing went crazy. Took it out back to fresh air outside and turned off. Passed the test! Just a heads up for those looking to purchase one...go for this battery operated and NOT the one that plugs into the wall with a battery backup. Any time a dog or kid rubs into the one for the electrical outlet, it goes off. Every couple weeks, goes off. Piece of junk! This one on the other hand, is small, looks good, and in my situation, it worked great. Gives me a piece of mind for family safety.

We opened the windows to air out the house and set this detector on the counter. The alarm never sounded but it’s an assurance we need should a similar situation arise in the future.

I gave only 4 stars because I don't know how well they will work and hopefully never will need to find out. But they r small enough and easy to install. And they don't look like eyesores on the walls. Price was right, so I recommend.

Something inside is putting pressure on the batteries which forces the battery door to “bow”. I’ve managed to secure the whole thing with rubber bands and it seems to work.

Our last Kidde Detector had to be replaced because of age and I knew the Kidde brand so I purchased another one as the replacement. We feel better with the alarm and just thankful it has not had to alert us over it's lifetime.
