Most Versatile

MTI Industries Carbon Monoxide Alarm

Lacking a decent spot to put a carbon monoxide detector can be a pain. Luckily, this unit is super easy to set up and to take down. Just stick it on a reasonably high surface, and you will be good to go.

Accuracy is no problem for MTI’s carbon monoxide detector. It is sensitive enough to pick up on subtle changes but can be a little too sensitive at times. Also, there is no way to turn it off quickly in case of a false alarm. However, those are easy to overlook and manage if you need something to work in several ways.

You do not have to worry about crazy weather changes setting this alarm off either. It can handle high and low temperatures with ease. Overall, this carbon monoxide detector is incredibly trustworthy and adaptable to various situations and setups.

Most Durable

Kidde Battery-Operated Carbon Monoxide Alarm

With an alarm loud enough to hear from quite a ways away, this carbon monoxide detector is ideal for those who are hard of hearing. The alarm will speak and tell you which one is going off, but that may not be a perk for some people. Regardless, the carbon monoxide detection capability is incredibly accurate.

An easy installation process allows you to set it up and forget about it. However, the batteries tend to run out more quickly than other models. If you tend to RV in locations with extreme temperatures, you may want to look elsewhere.

Even with these little quirks, this sensor’s ability to alert you of carbon monoxide is top-notch. Disregarding the unit’s variable battery life, this one will also last a long time, allowing you to have some peace of mind during your travels. The durability and sensitivity of Kidde’s carbon monoxide detector are unquestionable.

Atwood RV Carbon Monoxide Detector

The LCD screen that comes with this carbon monoxide detector lets you know even if the slightest change in levels occurs. The unique display allows you to monitor any increases, even if they do not set the alarm off. This way, you can keep an eye out for a rise in levels or address the problem before it gets worse.

Any change in carbon monoxide levels can signal that there is another problem somewhere. Early detection and how sensitive this detector will keep you on top of maintenance and leave you with peace of mind. You might have some trouble replacing the batteries when the time comes, but it is worth it.

Three types of lights signal different states of this carbon monoxide detector. All is well when green is blinking, but flashing red means an active alarm is going on. Lastly, a blinking red light indicates that the battery is on its last leg.

Best Hardwired Detector

Safe-T Alert LP/CO Alarm

As a hardwired detector, the Safe-T Alert deletes all the others out of the equation. Installation is easy, especially for a sensor of this type. The alarms are loud, but there is a possibility of the occasional false alarm.

Since it detects carbon monoxide and gas leaks like propane, this unit is excellent for RV living especially. With all the generators and appliances plugged in, you never know what could be lurking in the air. It can also adapt to extreme temperature changes, no matter where your journey takes you next.

On top of all that, you will never have to replace the battery. All you will need to do is replace it every five years or so. Protection from this carbon monoxide detector is well worth the extra effort of placement. It is hardwired, after all, so it takes a little more than other models.

Most Accurate

First Alert Carbon Monoxide Alarm

The First Alert carbon monoxide alarm is not only accurate, but it also has different colored lights and sounds depending on which alarm triggers. It is on the smaller side, and the lightweight design adds to the ease of installation. Also, the ability to detect smoke and dangerous gases are ideal for RV living.

Even though the alarms have great features, the sounds might not travel through the whole space. Because of this, it could be useful to have a few set up in several locations. As long as you follow the easy guidelines to put it up, your RV will be that much safer in just a few minutes. Each type of alarm has exceptional accuracy to alert you of both smoke and carbon monoxide issues.

When the battery is low, and the chirping sound begins, there is a button to mute the sound for up to eight hours. This option gives you time to get a new battery and replace it without the headache of constant beeping while trying to go about your day. Being able to turn it off is especially helpful to RVers that cannot get somewhere to find a replacement battery right away.

Recap: The Best RV Carbon Monoxide Detectors

Buying a New Carbon Monoxide Detector: What to Look For

When it comes to choosing a CO detector for your RV, there are some critical elements to consider. These components make up what your requirements should be and can vary in different situations.

The most important things to keep in mind are: how the detector will receive power, the level of detection, whether or not it has a smoke alarm, and if there is any additional useful information.

Power Source

Your setup will determine the type of carbon monoxide detector you need for your RV. A hardwired sensor will serve some better than others, and the same goes for battery-powered or plug-in units. Hardwired options do take a bit more work than the others, however.

If you need a detector with versatility in placement, battery-powered and plug-ins are your best bet. Hardwired sensors may require expert installation as well, which can be a hassle. However, they do not require battery replacement and are an excellent long-term investment. It is up to you to identify which model type will serve you best.

Level of Sensitivity

A carbon monoxide detector must have adequate sensitivity to detect increasing levels of the deadly gas. Without some sort of sensor, you risk carbon monoxide poisoning, which can be fatal. RV living proposes many situations where the invisible, odorless gas can accumulate and increase in levels fast.

Since there are ample opportunities for a carbon monoxide leak, you should have a detector in every room. If some sensors have more sensitivity than others, it is best to put that one close to possible sources, including generators and even lanterns. This positioning will help the detector react to any situation immediately. The more sensitive it is, the better equipped you will be for emergencies.

Combination vs. Standalone

If all you need is a carbon monoxide detector, this will be an easy choice for you. It could be highly beneficial for others to buy a combination of a smoke detector and a carbon monoxide detector. Luckily, both types have many options.

RVs sometimes already have some safety measures installed. However, it is possible to replace these if they do not suffice or need updating. You can always just install another one, especially if the one included can only detect smoke or fire.


Detailed displays for carbon monoxide detectors can tell you helpful details about the environment around it. Some sensors do not have models with a display, so making an informed decision can cause frustrations. If it is not something you think you need, the options are more open to you.

Carbon monoxide detectors with displays can have a simple digital screen or even be a Smart detector. It is likely not hard to tell whether you will need something more in-depth than the average unit. All those bells and whistles are not for everyone, after all.

Frequently Asked Questions

Where Should A Carbon Monoxide Detector Be Placed In An RV?

The most central location in your RV is best for your carbon monoxide detector. About 4-5 feet off the floor is where you will get best results. Carbon monoxide acts very similarly to hot and cold air so if it warms up in your RV the gas will rise and if it is cool, it will stay close to the floor, so a placement on a wall should provide the best results.

Why Is My Carbon Monoxide Detector Beeping In My RV?

If you are 100% sure there is no carbon monoxide in your RV, then the most likely cause of the beeping is that the batteries are low. Smoke and carbon monoxide detectors will often chirp when their batteries are low. This chirping runs the batteries down faster, but that also alerts you that it is time to change your batteries so that you are always protected as carbon monoxide is often an odorless and colorless gas.

Do I Need A Carbon Monoxide Detector In My Camper?

It is recommended that no matter what kind of camper you have that you have a carbon monoxide detector in your RV. Carbon monoxide is colorless and odorless unless it’s coming off of a generator. This makes it very hard to determine if there is poison in your RV until it is too late. Its better to have one and not need it than to not have it and possible face more dire consequences.
