The Best Carbon Monoxide Detectors in 2023

tom.baldridge

Carbon monoxide is a colorless, odorless gas that can be deadly if inhaled in large quantities. Carbon monoxide detectors are essential devices that help keep you and your family safe from this silent killer. These detectors work by detecting the presence of carbon monoxide in the air and sounding an alarm when levels become dangerous.

When looking for a carbon monoxide detector, it’s important to pay attention to the type of sensor it uses. There are two main types of sensors: electrochemical and biomimetic. Electrochemical sensors are more accurate and last longer, but they’re also more expensive. Biomimetic sensors are less expensive but may not be as accurate.

Another important factor to consider is the power source. Carbon monoxide detectors can be battery-operated or hardwired into your home’s electrical system. Battery-operated detectors are easier to install and can be placed anywhere, but they require regular battery replacement. Hardwired detectors are more reliable and don’t require battery replacement, but they’re more difficult to install.

We spent hours researching and testing various carbon monoxide detectors to identify the ones that provide the best protection for you and your family. In the following sections, we’ll discuss our top picks and why we recommend them.

Buying Guide

When it comes to buying a carbon monoxide detector, there are a few things to keep in mind to ensure you choose the best product for your needs. Here are some features to consider:

Sensor Type

The type of sensor used in a carbon monoxide detector can affect its accuracy and lifespan. The two most common types are electrochemical and metal oxide semiconductor (MOS) sensors. Electrochemical sensors are more accurate but have a shorter lifespan. MOS sensors have a longer lifespan but may not be as accurate. Consider which type of sensor is best for your situation.

Power Source

Carbon monoxide detectors can be powered by batteries or by being hardwired into your home’s electrical system. Battery-powered detectors are more portable and can be placed anywhere, but require regular battery replacements. Hardwired detectors are more reliable and don’t require battery replacements, but may be more difficult to install.

Display

Some carbon monoxide detectors come with digital displays that show the current CO levels in your home. This can be helpful in determining whether the levels are rising or falling. Consider whether a digital display is important to you.

Alarm Type

Carbon monoxide detectors can have different types of alarms, including beeps, flashing lights, and voice alerts. Consider which type of alarm is most effective for you and your family.

Other Features

Some carbon monoxide detectors come with additional features, such as a built-in nightlight or the ability to connect to a smart home system. Consider whether these features are important to you.

By considering these features, you can choose the best carbon monoxide detector for your needs. Remember to regularly test your detector and replace it according to the manufacturer’s instructions to ensure it continues to work properly.

Frequently Asked Questions

Where should I place my carbon monoxide detector?

We recommend placing a carbon monoxide detector on every level of your home, including the basement and near sleeping areas. It’s important to place them at least 15 feet away from fuel-burning appliances and never in areas with high humidity or near doors or windows.

How do I know if my carbon monoxide detector is working?

Most carbon monoxide detectors have a test button that you can press to ensure they’re working properly. You should also replace the batteries in your detector every six months and replace the entire unit every five to seven years.

What should I do if my carbon monoxide detector goes off?

If your carbon monoxide detector goes off, evacuate your home immediately and call 911. Do not re-enter your home until emergency responders have deemed it safe.

What is the difference between a plug-in and portable carbon monoxide detector?

Plug-in carbon monoxide detectors are designed to be mounted on a wall and plugged into an electrical outlet. Portable carbon monoxide detectors are battery-operated and can be moved from room to room. Both types of detectors are effective at detecting carbon monoxide.

Are there any specific requirements for smoke and carbon monoxide detectors?

The specific requirements for smoke and carbon monoxide detectors vary depending on where you live. We recommend checking with your local fire department or building code office to ensure that you’re in compliance with all regulations.

How can I check the carbon monoxide levels in my home?

The only way to accurately measure carbon monoxide levels in your home is with a carbon monoxide detector. We recommend purchasing a detector with a digital display that shows the current CO levels in your home.
