Another feature that I love in this RV detector is the “Alarm Mute” button and Rapid recovery sensor. The “Alarm Mute” button helps you control and silence the alarm whenever ventilation is in your RV. This feature will prevent false alarms from occurring.

On the other hand, the Rapid recovery sensor will automatically reactivate if there are still high propane levels in your RV. This important feature will notify you if there is still some danger lurking around in your RV and helping you be safe.

The only thing I dislike is if your RV has a weak or dead battery, it will continue to beep as it is a 12v carbon monoxide detector.

No device is perfect, and with this one, it needs 25% LEL before it sounds an alarm. For some, it may be a high level already, as you would smell gas at this point. If you want the device to detect gas better, place it in an elevated location if you have natural gas and a low area if you have propane.

What To Know Before Buying RV Carbon Monoxide Detectors


Here are some of the crucial things you should know while looking for the ideal RV carbon monoxide detector.

The different types of CO detector

Before buying a CO detector, you need to know about the different types first.

  • Smart

It can be connected to any device and sends a notification straight through your phone.

  • Dual-function

Can detect different threats such as CO, smoke, or fire in one device.

  • Battery-operated

Batteries are required to operate.

  • Digital

A device that shows a digital display of RV’s CO levels

  • Hardwired

Wired into an RV’s electric grid.

Benefits and Drawbacks of RV carbon monoxide detectors

An essential advantage that you can get from having an RV CO detector is that you can rest assured that you’ll be safe from harmful CO gases. It will help notify you of any danger so that you can take preventive measures.

The only drawback here is that if a CO detector is not placed well, false alarms may be triggered every now and then, or it won’t detect CO well.

Other Factors

  • Effectiveness

When it comes to effectiveness, a great CO detector will offer a higher level of sensitivity. Take note that levels measured in part per million, and most devices will sound an alarm at 70 ppm.

  • Digital Display

Rig owners tend to go for a more friendly-user model with a digital display. With this, you can monitor your rig’s CO levels at all times.

  • Lifespan

You should also consider the device’s lifespan. An RV CO detector usually lasts for 5-10 years.

  • Stand-Alone or Combo Model

Stand-alone models would only detect carbon monoxide, but they would be very affordable. On the other hand, a combo model would detect carbon monoxide and smoke, but it would cost more.

  • Installment

It’s a definite must that you buy a CO detector that’s easy to install. Get a device that you can set up all by yourself.

  • Cost

For everything you buy, you must check the item’s price. Prices may vary depending on the device’s features, so make sure to get the best product for your money.

  • Power Source

There’s a variety of power sources that you can choose from, such as battery-powered, plug-ins, hardwired, and plug-in/battery. If you don’t like changing batteries, select a hardwired model. Otherwise, make sure to get a battery-powered model that lasts for ten years.

To help you find the suitable CO detector for your rig, I’ve compiled some of the most frequently asked questions for you.

How Do Carbon Monoxide Detectors Work

Carbon monoxide detectors work just like smoke detectors which produce a loud alarm to notify you of dangerous CO levels in any motorhome. Having a CO detector is essential for any rig owner as it helps you and your rig stay safe at all times.

Where Should A Carbon Monoxide Detector Be Placed In An RV

Make sure that it’s in a centralized position, 5 feet from the RV’s floor. Carbon monoxide stays low when the air is cold. Simultaneously, it rises when the air warms up, so putting your CO detector in a centralized position will ensure that it functions well in both scenarios.

Why Does My Carbon Monoxide Alarm For RV Keep Beeping

If it’s a battery-powered detector, it may mean that you need to replace the batteries. However, suppose your RV carbon monoxide detector keeps beeping. In that case, there may be a slowly rising carbon monoxide level, so stay safe and get away from the rig.


Overall, you should consider all factors in buying the best RV carbon monoxide detector. Finding the best fit for your RV may be challenging with the wide range of variety to choose from. But always keep in mind what are the things that you need most and how convenient will this CO detector be for you in terms of price, installment, etc. Make sure to think long and hard before making the decision, as the safety of your rig lies in your hands.
