The Best Carbon Monoxide Detectors for 2020

By WenSue |

Carbon monoxide is a poisonous gas that claims hundreds of lives each year. Hence, a carbon monoxide detector is important to keep you and your family safe from this silent killer of a gas.

But with the plethora of carbon monoxide detectors in the market, it can be hard to choose the right one for your needs. So, we’ve rounded up our best carbon monoxide detectors list for 2020. Read on to see which safety device is best suited for your home!

Types of Carbon Monoxide Detectors

Carbon monoxide detectors sense rising levels of carbon monoxide around the environment it’s placed in. The detector sets off an alarm once it senses a harmful gas level. This typically happens at carbon monoxide levels of 40-50 ppm and above. The most common types of carbon monoxide detectors as below:

  • Battery-operated – These are the basic detectors that need batteries to operate.
  • Digital – These detectors use digital screens to show you the exact carbon monoxide levels in your environment.
  • Hardwired – These detectors are wired within your electrical grid. If electricity in your home goes off, your hardwired detector won’t work, too.
  • Smart – These are detectors that sync with your home safety systems. They can also run diagnostics once they’re synced to an app.
  • Dual-function – These detectors are multi-functional. They can sense smoke and fire apart from carbon monoxide.
