Carbon monoxide poisoning happens to around 20,000 people a year and some cases even result in death. Carbon monoxide has always been referred to as a silent killer. This is because it is odorless, tasteless, and colorless. Our bodies do not react well to carbon monoxide, leading to throwing up, intense headaches, and passing out. Poisoning most commonly occurs in indoor places because there when it is present outside it has enough room to dissipate. However, smaller areas like your home or RV are subject to this danger. That is why we have included this list of some of the best carbon monoxide detectors for your RV.

You might be wondering what a carbon monoxide detector is. When looking at these devices at their face value, they have similar characteristics to a smoke detector. Using biomimetic strips, semiconductors, and electrochemical sensors these alarms are able to detect dangerous levels of carbon monoxide and alert you accordingly. It is recommended to keep these detectors outside where you sleep, being able to alert you awake before being potentially poisoned.
