6 Reasons to Buy a Smart Carbon Monoxide Detector Today (and Which Are Best)

Key Points

  • Carbon monoxide (CO) detectors are important and potentially lifesaving devices that should be in every home, as over 400 Americans die annually from carbon monoxide poisoning.
  • Smart carbon monoxide detectors provide the ability to control the alarm from a mobile device, reset the alarm remotely, and receive detailed alerts with pre-recorded messages.
  • Smart detectors also offer the ability to learn about indoor air quality, providing information on volatile organic compounds and real-time CO gas levels.
  • They can easily be added to existing smoke detection or security systems, and can send notifications to your phone when you are away from home.

Carbon monoxide (CO) detectors are an important and potentially lifesaving device that should be in every home. According to the CDC, over 400 Americans die annually from carbon monoxide poisoning, with ER visits surpassing 100,000.

Many modern carbon monoxide detectors also integrate smart technology that communicates with other devices in your home. Some also incorporate other functionalities, such as smoke detection.

The reason a carbon monoxide detector is critical is that, unlike smoke, carbon monoxide has no scent. In fact, most people do not have a reaction to it until it’s too late. Buying a smart carbon monoxide detector provides an extra layer of safety for your family.

Background on Carbon Monoxide Detectors

Carbon monoxide detectors come in a range of different shapes and sizes. Many of them serve a dual purpose and also contain a smoke detector. Most jurisdictions require carbon monoxide detectors to be installed in new homes, as well as rental properties.

These devices are crucial because they save lives by sensing when dangerous levels of CO are in the air. CO gas is a byproduct of unburnt fuel that can come from a range of sources, such as generators, stoves, and fireplaces.

Simple carbon monoxide detectors do a sufficient job and may run on batteries or plug into a wall outlet. However, no carbon monoxide detector lasts forever, and most manufacturers recommend replacing them every seven to ten years.

Reasons to Buy a Smart Carbon Monoxide Detector

Let’s explore some of the reasons to consider buying a smart carbon monoxide detector.

Reason 1: Control the Alarm From a Mobile Device

Nothing is worse than a beeping alarm going off with no way to disable it. Even after carbon monoxide levels are safe, the detector will continue to chirp until it is reset. This is when most people would reach for a broom or a stick to press the reset button on their detector.

Fortunately, this is not a problem if you have a smart carbon monoxide detector because you can reset the alarm from the convenience of your phone. Resetting the alarm remotely is a must for people with tall ceilings, where the alarm is out of reach. It also allows you to reset the detector if you are away from home.

Reason 2: Learn About Indoor Air Quality

A normal carbon monoxide detector is pretty limited since it only sounds an alarm when it detects a certain level of carbon monoxide. Most detectors provide vastly more information and do much more than just trigger an alarm. Smart detectors provide details such as the exact parts per million of CO gas.

The exact way this works varies by brand, but most have an app that lets you view CO levels in real time. However, some detectors take things a step further by using internal sensors to detect overall air quality.

This is great for people with respiratory problems, as the detector can provide the exact amounts of volatile organic compounds in the air.

Reason 3: Receive Detailed Alerts

Another benefit of a smart carbon monoxide detector is that it provides detailed alerts. For instance, a standard detector will beep until the air clears. Then, you must go up to the detector and press the reset button. However, a smart carbon monoxide detector will tell you what is going on with a pre-recorded message.

Because most houses have more than one carbon monoxide detector, a smart detector can help by telling you which one detected the high amount of CO gas. In contrast, a wired CO detector without smart capabilities will set off all detectors in the home, but you will not know where the gas is most prevalent.

Reason 4: Easily Add to Your Smoke Detection or Security System

CO detectors are often paired with smoke or heat detectors. Therefore, you can easily swap out your basic smoke detector with an all-in-one device. Even better, you can typically match a smart carbon monoxide detector to your home’s existing smart infrastructure.

If you already have smoke detectors, you can replace one in an appropriate room with a combination unit. More importantly, many alarm systems also support monitoring for carbon monoxide.

Adding a smart detector to an existing alarm system can provide advanced smart functionality, and it can also alert a monitoring service in an emergency. Of course, you can skip hardwired CO detectors and instead go with a wireless system that connects to your existing smart devices.

Reason 5: Get Notifications While You Are Away

A smart carbon monoxide detector can quickly alert homeowners of a CO leak. 

Every homeowner has concerns about something bad happening while they are away. But a smart carbon monoxide detector can give you peace of mind no matter where you are.

Like a conventional CO detector, a smart one will produce an audible tone to warn everyone in the house to leave. However, it will also send a notification to your phone, which you can then view in an app.

After receiving the notification, you can call a friend or authorities to check on the house and ensure it is safe. But before going inside, you should let the house air out. You can then go back to the app and check that the levels are safe.

Reason 6: Alerts You When It’s Time for Service

Many homeowners are shocked to learn that carbon monoxide detectors have a limited lifespan. They assume that changing the batteries and performing regular tests is enough, but the truth is most detectors are rated for a maximum of 10 years.

That poses a problem since you can easily forget when you installed the detector. Most CO detectors have a sticker on the side with an expiration date. But smart detectors provide the added benefit of letting you know when it is time for a replacement.

In addition, most will also send a regular status report to let you know the condition of their batteries and sensors. This can help you plan ahead when it comes to buying replacement batteries and detectors before the annoying reminder alarm starts going off.

The Best Carbon Monoxide Detectors

If you are considering a smart carbon monoxide detector, you should think about any smart systems already present in your home.

Frequently Asked Questions

How is carbon monoxide detected?

There are a few different carbon monoxide detectors, but most use a biomimetic sensor with a color-changing gel. The gel changes colors when exposed to dangerous levels of CO gas. An electrical sensor detects the color change and triggers the alarm.

Why is carbon monoxide so dangerous?

When you breathe in carbon monoxide, the gas gets trapped in your red blood cells and displaces oxygen. As the levels build, your body cannot move sufficient amounts of oxygen to vital organs, eventually leading to death.

Do you need a carbon monoxide detector if you don't have gas appliances?

A common misconception is that you don’t need a carbon monoxide detector if you don’t have gas appliances. This is completely false because there are many ways carbon monoxide can enter your home, including vehicle exhaust, generator exhaust, or even a fireplace.

Where should you mount a smart carbon monoxide detector?

It is best to contact someone locally who can consider the exact layout of your home for the best location. However, it is recommended that carbon monoxide detectors be placed outside of bedroom doors and on each floor of your home.

Do certain carbon monoxide detectors work better than others?

All carbon monoxide detectors sold in the US should have an Underwriters Laboratories sticker, indicating it has undergone rigorous testing. Some detectors may go off slightly sooner than others, but any devices with a UL certification will provide ample detection.
