Because it can’t be smelled, seen or tasted, carbon monoxide is the leading cause of poisoning worldwide. It could be infiltrating your home right now.
This is a scary thought, but there’s no reason to stay at risk. Protect yourself by purchasing a quality carbon monoxide detector. It could be the one thing that saves your life in a silent emergency.
Carbon Monoxide Detector Overview
Below, we’ve assembled 10 of the best and most popular carbon monoxide (CO) detectors available today. Some monitor carbon monoxide only, a couple double as smoke alarms and one can even detect flammable gases.
Good: This highly portable carbon monoxide monitor runs on a high-capacity battery built to last as long as the unit itself: 10 years. This, by itself, is a safety feature.
Not so good: Aside from a small display and peak level memory, this monitor lacks some of the advanced features and functions found in other devices.
Bottom Line: This is a good yet basic monitor with the added bonuses of an LCD display and a battery that you never have to change.
Good: A simple carbon monoxide detector with only one button, this affordable CO alarm is very easy to install and use.
Not so good: It doesn’t have the ability to detect smoke or gas and can’t be plugged into an electrical outlet.
Bottom Line: If you don’t need a multi-functional detector and you prefer not to mess around with a fancy interface, this simple, affordable detector should suit you fine.
Good: Putting itself a cut above, the Nest Protect communicates with your cell phone as well as other Nest systems. It can also talk you through various emergency and alert situations.
Not so good: Too advanced for users who just want a simple carbon monoxide alarm.
Bottom Line: If you like the idea of having a smart carbon monoxide and fire detecting device, this one is certainly worth a look.
Good: This direct-wire, ceiling mount, two-in-one system detects carbon monoxide and smoke and indicates either hazard via two different lights.
Not so good: Doesn’t include certain special functions such as the ability to track peak levels or to use voice notifications to tell you the nature of the problem.
Bottom Line: A good choice for people who specifically want a hard-wired, ceiling mount system and the ability to detect smoke.
Good: A well-priced monitor with voice alerts, carbon monoxide and smoke detection, peak memory and an end-of-life alert.
Not so good: The lack of a digital display makes it difficult to keep tabs on carbon monoxide levels at a glance.
Bottom Line: Given its abilities and the low price, it will be hard to find a carbon monoxide detector with more value for your money.”
Good: This plug-in CO monitor from a trusted name in the alarm industry includes a backup battery, peak memory, end-of-life alert, and a backlit digital display.
Not so good: Though all the basics are covered, no advanced features set this monitor apart from others.
Bottom Line: This is a good-quality monitor that will work for people who prefer the ease of use offered by simple controls along with a backlit LCD display.
Good: Built to plug directly into an electrical outlet, hang on the wall (using a 6-foot power cord), or sit on a table, this competitively-priced carbon monoxide detector also features CO level memory and an illuminated display.
Not so good: Unlike most, it does not have an end-of-life alert that notifies you that it’s time to replace the monitor.
Bottom Line: As long as you can remember that an error code around the 10-year mark means that it needs to be replaced, you should be fairly satisfied with this carbon monoxide alarm.
Good: This tough, durable, 100% waterproof portable carbon monoxide detector is built for use on the job site and can easily be carried around on a belt or in your pocket.
Not so good: Since it isn’t built for home use, it’s short on some of the features and functions of the others on our list.
Bottom Line: Given the great consumer feedback it has received and what it can do, this is simply the best industrial carbon monoxide detector we found.
Good: With a long-lasting 10-year lithium battery, you will never need to replace the battery in this monitor, nor will it fail in a power outage.
Not so good: Some people may find this unit to be larger than they would like and, unfortunately, it doesn’t detect anything other than carbon monoxide.
Bottom Line: Very similar to another option on our list, this monitor’s ability to sit upright on a table makes it somewhat unique.
Good: With the ability to detect explosive gases such as propane and methane in addition to measuring carbon monoxide levels, this monitor goes above and beyond.
Not so good: It does not have a backlit display for use in dark environments and lacks voice alert capability.
Bottom Line: A good choice if there is even a remote possibility of propane or methane gas building up in your home and you don’t want a detector for each.
