According to recent studies, carbon monoxide poisoning is the top cause of death by poisoning in America. It’s tasteless, odorless, and is impossible to detect with the senses alone, which is why carbon monoxide has earned its nicknames as the “silent killer.”

The thing about this gas is that it is always present, especially when you burn something like gas, wood, oil, or gasoline. It may not be dangerous when you’re outdoors, but in a confined space, carbon monoxide is lethal when allowed to reach high levels.

The 5 Best Carbon Monoxide Detectors in 2019Because this gas is virtually undetectable, the only time you’ll know that there’s a high concentration of carbon monoxide in your surroundings is when you begin to show the signs of carbon monoxide poisoning. These signs include nausea, headaches, dizziness, confusion, and eventually loss of consciousness.

Many people recognize the need for a carbon monoxide detector in their home or work area, especially if the space is small. These detectors can give us an early warning that the levels of carbon monoxide in the air is considerably high so steps can be taken to reduce the carbon monoxide or evacuate the area. This buys time for people to act or prevent an accident or, in worse cases, the loss of life and property. Given the nature of carbon monoxide, investing in a detector is a small price to pay for the safety of your family or personnel.

Right now, you may be wondering how you can choose the right detector for your needs. We have done the research for you and have come up with the five best detectors in the market today. To make the selection process even easier for you, we also covered some of the essential considerations when it comes to choosing a carbon monoxide detector. All the information provided here should help you in your search for a detector that will meet your specific needs and budget.


Considerations When Choosing a Carbon Monoxide Detector

Types of Carbon Monoxide Detectors

Generally, there are three types of detectors: Electrochemical, biometric, and metal oxide semiconductor sensors.

Electrochemical detectors are considered the best type of detector because they use chemicals and electrodes that send out a current and activate the alarm. Biometric sensors, meanwhile, use gels that change color when they absorb a certain level of carbon monoxide. Metal oxide semiconductor sensors make use of silica chips that send out electrical signals to set the alarm.

Some detectors are designed with a digital screen that shows the levels of carbon monoxide in the surroundings. This gives you an idea of how much gas in the immediate vicinity with an accurate reading that’s displayed on a digital screen.

Battery Operated or Hardwired

The most common type of carbon monoxide detector runs on batteries and may or may not have a digital screen. The problem with battery-operated sensors is that you constantly need to check them to make sure they’re still working. There are units available that give out a warning signal when it is time to change the batteries.

If you’d rather not worry about changing batteries, your best option is to get a detector that’s plugged directly into the electric grid. You won’t ever have to worry about whether the device is working or not, unless the power goes out.

Additional Sensors

It isn’t unusual to find a carbon monoxide detector that can also detect smoke. There are several models that can also detect other harmful gases, but they typically cost more and can be difficult to find.

Smart Sensors

Smart Sensors are the best the market can offer. These devices do their own diagnostics checks to make sure there are no problems and can be synced with apps on your devices so that you can monitor the gas levels in the area even while you’re away.
