Nest Protect Review
Pros
  • Easy setup
  • Clear warnings, including spoken alarms
  • No hub required
Cons
  • No more gestures to shut it off
  • Limited integration with Nest thermostat

Like most smart carbon monoxide detectors, this one doubles as a smoke detector. You’ll be thankful that this product pulls double duty, as its price tag (which hovers around $100) makes it the most expensive item on this list. However, you’re getting a lot for your investment, including reliable carbon monoxide and smoke detection, smartphone alerts, and an impressive 10-year lifespan for its sensors. It also includes a unique pathlight feature, which serves as a nightlight when motion is detected.

Budget-minded shoppers will love everything offered by the affordable AEGISLINK carbon monoxide detector.

Toss in an LED indicator to alert you to the monitor’s status, a simple design, and dual function as a smoke detector, and it’s easy to see why this smart carbon monoxide detector is so popular.

Amazon Smart Air Quality Monitor

Pros
  • Sleek design
  • Measures several air quality parameters
  • Easy integration with Echo devices
Cons
  • Not officially certified

Amazon makes a wide assortment of smart home products, so it should come as no surprise that it makes one of the best smart carbon monoxide detectors on the market. This device is actually billed as an air quality monitor, but it fully supports carbon monoxide detection – and having readings for particulate matter, VOCs, humidity, and temperature are a nice bonus. However, there are a few caveats to this device. For one, it’s not officially certified as a carbon monoxide alarm, so consider using it in conjunction with a traditional detector for optimal coverage. It also doesn’t have a speaker, so it’ll need to connect to an existing Alexa device to issue alerts. Caveats aside, this is a powerful, all-around detector that works incredibly well as an add-on to existing systems.
