Carbon Monoxide Detectors: Ratings of Sources

Not Dated
CO & Smoke Alarms
by Editors of ConsumerReports.org
Our AssessmentConsumerReports.org tests 12 carbon monoxide alarms in two categories: interconnected alarms and stand-alone alarms. Some are only CO alarms, others are combination carbon monoxide/smoke detector models. Ratings are given for the ability to detect both low and high levels of CO, plus the quality of the display or voice feature. Top models receive Recommended recognition, and best values are designated as Best Buys.

Carbon Monoxide Alarms
by Contributors to Amazon.com
Our AssessmentAmazon.com hosts user reviews for lots of carbon monoxide detectors, many with hundreds of reviews. Others, on the other hand, have relatively little feedback. Navigation is easy, and you can choose to look at all CO alarms, or just those that are battery operated, hardwired or that have a digital read out. Separately, Amazon.com also has reviews for combination smoke and carbon monoxide alarms.
3. Walmart.com

Carbon Monoxide Alarms
by Contributors to Walmart.com
Our AssessmentWalmart.com offers fewer carbon monoxide detectors than Amazon.com, and fewer still that have significant feedback (50 or more reviews). Reviews tend to be short, but owners can say whether or not they'd recommend a CO alarm to a friend, and that assessment can be helpful.

Carbon Monoxide Alarms
by Contributors to HomeDepot.com
Our AssessmentAs is the case at Walmart.com, most carbon monoxide alarms and combination smoke and carbon monoxide alarms at HomeDepot.com don't get a ton of feedback. Still, these reviews can help fill in the picture regarding user satisfaction of a CO detector you are considering.
5. Lowes.com

Carbon Monoxide Alarms
by Contributors to Lowes.com
Our AssessmentLowes.com is another national home improvement and hardware chain that offers CO alarms. Only a handful of models are offered, however, and most get relatively little feedback -- less than any other site. Still, and again, it's worth a visit to get the most complete picture of user satisfaction if you are considering a carbon monoxide alarm that they carry.

Nest Protect review
by Lindsey Turrentine
Our AssessmentTechnology sites almost never review CO detectors -- with the notable exception of the Nest Protect, a smart CO and smoke detector that connects to the Internet, and to an app on your smartphone or tablet. The review here has been updated twice since originally written, mainly to account for the detector's recall and return to the market. The review is in-depth and hands on. The Nest Protect earns a 4.5-star rating.
