Buying Guide for Carbon Monoxide Detectors

Have a look at the things that you should consider while buying the best portable carbon monoxide detector for travel:

Smoke Detection

When buying the carbon monoxide detector, you need to choose the one that detects smoke plus carbon monoxide at the same time. If you have already installed the smoke detector in the house, it’s better to opt for a carbon monoxide detector.

However, if you don’t have smoke detectors at home, it’s best to invest in a detector that can detect smoke plus carbon monoxide.


When buying a carbon monoxide detector, choose the one according to your preference, whether you want the one plugged in the outlet, hardwired, or the battery-powered one.

Battery-powered units are such that you can place them anywhere within the house. However, you need to check their battery levels. Plug-in carbon monoxide detectors are the ones where you don’t have to look for their battery, but you are limited in terms of connecting them with the outlets available nearby.

Lastly, hardwired units are the ones that need complex installation.


Several carbon monoxide detectors in the market are available in the 2-in-1 form, allowing you to check smoke and carbon monoxide levels. The detectors are usually available in the interconnected form, allowing you to check the alarm.

If one CO detector goes off on the first floor, it will trigger the alarm on the second floor. This will prevent you from any missing notices.

Moreover, carbon monoxide detectors can be easily integrated with smart home devices like smartphones, ALEXA, and more. However, if you cannot buy the interconnected alarms in conditions, you can opt for numerous units to place all over the home at different levels.

Sensors in carbon monoxide detectors

CO detectors come up with one of the following sensors:

  • Biometric detectors have color-changing gels which can easily absorb carbon monoxide and trigger the alarm.
  • Electrochemical sensors make use of electrodes that are present in chemical solutions. They can sense the alteration within electric currents at the time of the presence of carbon monoxide.
  • Metal oxide semiconductors come with silica chips that can detect the carbon monoxide and then send electrical signals which can trigger your alarm.

Types of carbon monoxide detectors

With a wide range of carbon monoxide detectors in the market, the different types include the following:

  • Digital detectors: they show the level of carbon monoxide over your digital screen.
  • Dual-function: they sense the threat level of different items like fire, smoke, and carbon monoxide.
  • Smart detectors: they run the diagnostics and then sync well with home automation apps.
  • Hardwired: these detectors are wired within the electrical grid of your home, and they work till the time of power outage.
  • Battery-operated: these detectors come with basic sensing or display, which means they need batteries for operation.

Final Verdict

So, don’t delay any further save yourself and your family against high levels of carbon monoxide at your homes, kitchen, RV, or garage. Just check out your local regulations within the area and buy the detector accordingly.

Pick the detector with your choice of power source to install them as per your needs. Choose smart detectors which can sync with other home appliances and also offer a voice control feature.

Invest in an excellent carbon monoxide detector now and keep yourself safe!

How to know that the carbon detector is usually working?

In most conditions, the detector results in flashing of green power.

How to know that the carbon detector is broken?

The yellow indicator in most doctors results in a beeping sound after every few seconds with an LCD showing Err.

How to know that it’s time to change batteries?

The detectors come with a yellow indicator light which results in di after every 35 seconds.

Where is better to install the gas detectors?

Choose a suitable position for installing the detectors as per specific gas gravity. The installation height is high from the floor, around 12-40 inches, with a gas source of about 60 inches.

Avoid placing the gas detector close to the source of interference. The direct airflow from fans, doors, vents, windows, steam, or oil vapor sources can affect the efficiency of gas detectors.

It’s best recommended to place the carbon monoxide detectors in the garage, kitchen, basement, your room, and others.

What are the familiar sources leading to carbon monoxide poisoning?

Carbon monoxide is a type of invisible, silent killer gas. CO gas is released when burning natural gas, gasoline, oil, propane, wood, or charcoal. The release of CO in garages, RV, or inside homes can be dangerous for users, while in outdoor spaces, it does not cause much hassle.

What are the different symptoms of suffering from carbon monoxide poisoning?

Carbon monoxide poisoning comes with flu-like symptoms, including nausea, vomiting, dizziness, headaches, fainting, or confusion.

What to do if I suffer from CO poisoning?

If at home, then get out and call 911 immediately. Carbon monoxide poisoning can affect the parts of your body, so it’s better to seek medical attention immediately.

How commonly CO poisoning occurs?

Every year, around 400 Americans suffer from accidental carbon monoxide poisoning, with 20000 people being admitted to emergency areas of the hospital.

Who is more susceptible to suffer from CO poisoning?

Every one of us is susceptible to suffering from carbon monoxide poisoning. But people with physical illness, older adults, children, and pets are at high risk to suffer from carbon monoxide poisoning.

How does the carbon monoxide detector work?

It works similar to the smoke detectors and detects the level of carbon monoxide within the room.

  1. This MTI is the third one of these I’ve purchased. Installed easy. the device came with about 5 in of wiring. So I had some leeway for installation. does have a test button. and does have the light when it has power. Which is reassuring my old broken unit did not have a test button.

  2. I used this MTI Industries’ 35-742-BL Dual RV LP/CO Alarm and it’s an excellent choice. I can install easily.  This device can detect both gas leaks and CO gas at the same time. It has a plug-in 12V power source, so I won’t ever need to replace any dead batteries. Besides that, this product can withstand the rugged environment of an RV and function at any temperature between 40 F and 158 F. Therefore, I feel fine when I travel.
