The Best RV Carbon Monoxide Detector: Top 5 Picks

A good RV carbon monoxide (CO) detector will constantly beep if it detects a good amount of CO in your vehicle. This allows you to take prompt action and avoid possibly significant problems. But what is the best RV carbon monoxide detector you can get in 2022? We conducted thorough research and picked the top 5 available right now!

What is a RV Carbon Monoxide Detector?

In order to prevent CO poisoning, carbon monoxide detectors emit loud sounds when they detect carbon monoxide or other dangerous gas levels.

Human senses cannot detect carbon monoxide since it has no odor, taste, or color. Hence, when harmful levels of CO are accumulated indoors without a person ever being aware of it, it may cause illness.

However, you can prevent the poison associated with CO by taking simple precautions like installing a carbon monoxide detector and maintaining fuel-burning equipment.

Below, we have compiled a list of the best RV carbon monoxide detectors and listed the factors to take into consideration while looking for the best RV carbon monoxide detector.

RV Carbon Monoxide Detector FAQs

best rv carbon monoxide detector

1. How does a carbon monoxide detector work?

A microchip made of silicon encased in a pliable shell transmits an electrical charge into a tiny detecting chamber containing a carbon monoxide sensor. The sensor detects and measures CO concentrations in the air. If the device sensor detects excessive carbon monoxide levels, the silicon microchip will sound an alarm.

2. Where should a carbon monoxide detector be place in an RV?

Ensure it is in a centralized strategic point, at least five feet from the floor of the RV. Carbon monoxide levels remain low when the atmosphere is cold, and they increase when the atmosphere warms. Thus, positioning your carbon monoxide detector in a centralized strategic point will guarantee that it performs well in all cases.

3. Why does the carbon monoxide alarm keep going off in my RV?

If a battery powers your device, it is a possible indication that the batteries need to be replaced. However, it may also mean that the carbon monoxide level is rising gradually. So you should pay close attention and adjust accordingly before the situation gets out of hand.

4. How long do RV carbon monoxide detectors last?

Carbon monoxide detectors should be continually checked to make sure they are working properly. It is suggested to check them before each camping trip in your RV. If purchased before August 2009, your detector has an end of life warning and will continually beep when it is time to be replaced. In general, they last around 7 years.


A CO detector is a must have for first time RV owners. Picking the Best RV carbon monoxide detector demands careful research and consideration of all kinds to ensure high-quality performance. Furthermore, it may be challenging to choose from all of the alternatives available, but note that the safety of your household, workers, campers, and anyone else depends on your decision.
