Best Carbon Monoxide Detector, Expert Recommendations

I have researched about the best carbon monoxide detector for the past few days because I want to upgrade my home safety system. I read reviews on The New York Times, Consumer Reports, and CNET, and they all seem to agree that these two stand out the most:

X-Sense Smart Smoke Detector Carbon Monoxide Detector Combo

Kidde Smoke & Carbon Monoxide Detector

Both are packed with smart features like voice alerts, smartphone notifications, CO detection, and the ability to pinpoint exactly which room is affected. The reviews are excellent—but now I’m stuck trying to decide which one would best suit my home setup.

In my house, I have a mix of hardwired smoke detectors already installed, but some rooms don’t have wiring and would need a battery-powered option. I’m also wondering about long-term maintenance, reliability, and which type might be more convenient overall.

So if anyone has experience with either model, I’d really appreciate your advice!
Should I go battery-powered or wired? Any tips or recommendations would be super helpful.Thanks in advance!

No experience I’m afraid but an idea of what to look for.

If you go for wired you want battery backup somewhere, whether part of a home battery system or a small rechargeable battery in the device.

I no longer combust anything in the house and didn’t replace my CO detector at the end of its life.
