Review: First Alert Carbon Monoxide Alarm

smart phone and home security device

Everyone has heard about the dangers of carbon monoxide. After all, unlike the gasoline you put in your car, there is no color, taste, or scent to carbon monoxide. This can make it extremely dangerous, even fatal, if it turns out you have carbon monoxide leaking somewhere in your house. To protect you and your loved ones from ever accidentally inhaling too much carbon monoxide, you need an alarm to sense for this. The First Alert Carbon Monoxide Alarm, along with the other best choices on this list, will prevent any such event from occurring. Carbon monoxide is released into the air every single time you burn something, regardless of the source. This means that whether you are on your stove, using gasoline to fuel your car, or starting a fire in your fireplace, you are releasing small amounts of carbon monoxide. Obviously, most of these activities usually occur outside, where there is plenty of air and circulation and no risk involved. But in small spaces such as a room or garage, carbon monoxide is a whole different story.

Comparison Table

It is also possible for your appliances to leak carbon monoxide without anyone’s notice since it is impossible to detect. No matter the reason, there is extra carbon monoxide in your home, whether it is from your stove or car in the garage, the First Alert Carbon Monoxide Alarm, along with our other carbon monoxide alarm choices will be able to alert you in time to get to fresh air.

It may certainly seem difficult to choose just one carbon monoxide alarm, and that is why we collected this roundup of both the First Alert Carbon Monoxide Alarm and a bunch of its competitors on the market. Though you may not know everything there is to know about carbon monoxide alarms yet, by the end of this article you will feel confident in purchasing the right alarm for your home.

​What Is a Smoke and Carbon Monoxide Alarm?

As stated, a smoke and carbon monoxide alarm will help protect you from any dangerous fumes in your home so that you stay safe. Smoke alarms detect for ordinary smoke, which you are able to smell and see unlike carbon monoxide, but you still want an alarm for it since it means there is likely something burning. Together, both of these functions in an alarm will ensure that regardless of what happens in your home, you are made aware and can get out to fresh oxygen supplies.

Carbon monoxide alarms work in one of three ways. They may be constructed with biomimetic detectors, which use gels that sense the levels of carbon monoxide, and after they absorb too much, they will sound an alarm. Then, there are also metal oxide semiconductor carbon monoxide alarms, which will use silica chips to detect dangerous levels of carbon monoxide, after which electrical signals set off an alarm. Finally, there are also electrochemical carbon monoxide alarms that use electrodes to detect even the smallest fluctuation in the electrical currents when carbon monoxide levels are in that air, and then an alarm sounds.

Now that you know the basics of how carbon monoxide alarms function and the different types you may encounter, we will break down some specific models further and list features, price, and pros and cons so you can figure out which carbon monoxide alarm is just right for your home.
