Carbon monoxide (CO) is a colorless, odorless gas that comes from fireplaces, furnaces and portable generators, as well as other devices that involve combustion. This gas is deadly and impossible for humans to detect without help. More than 400 Americans die from unintentional CO poisoning each year, according to the CDC.

Consequently, having a carbon monoxide detector in your home is of utmost importance. Here's the best place to install a carbon monoxide detector in your home.

Before you buy, consider smart carbon monoxide detectors, with features that make your life easier and safer. Here's what you need to know about this important device.

Plus, here are the safety checks homeowners should be doing every year:

How Smart Carbon Monoxide Detectors Work

Smart carbon monoxide detectors measure the level of CO gas in your home and alert you if the level is too high. Most smart carbon monoxide detectors are also smoke detectors. These devices are considered "smart" because they have apps and voice control features, using Alexa or Google Assistant. For example, you can get remote notifications on your phone if there is a build-up of CO gas (or a fire) with the Nest Protect 2nd Gen smoke and CO alarm.

Carbon Monoxide Detector Features

The CDC recommends purchasing a detector with a digital screen that measures the level of CO in your home. Smart carbon monoxide detectors are particularly handy because you can monitor gas levels on the device's app from wherever you are.

More sophisticated smart detectors connect with your security devices and track the battery level. Some, such as the Onelink Safe & Sound by First Alert, also can play music or audiobooks while it monitors your home.


Most smart carbon monoxide detectors can be attached to a bracket on your ceiling or wall. The CDC recommends installing carbon monoxide detectors near bedrooms so those sleeping can hear it in an emergency. It's also a good idea to install one in your basement, or the garage if it's attached to your house. However, never install your CO detector like this. You should also install residential fire sprinkler systems to better protect your home.


Expect to pay from around $50 to $200 for a smart carbon monoxide detector. Typically, the more features these devices have, the higher the price. Next,  check out these 20 things in your home may be a fire hazard.
