It's super easy to write off the importance of a carbon monoxide detector.

A few years ago, I kept getting sick anytime I went to downstairs to work in the basement. I joked that it was a CO leak, and figured my headaches and exhaustion were just from getting stressed.

It was carbon monoxide. Turns out the person who had come to work on our furnace accidentally detached the vent or something of the sort. We got off lucky.

Make sure you have CO detectors.

In case you are looking for battery operated, try this two pack at HomeDepot, which comes out to about $16/unit. Amazon sells for $26.95/each

Is 71 the real price? A combo smoke and co alarm usually goes for like 30-40. Is it just 71 bc it's plug in vs hardwired?

I'm pretty confident that my CO Kidde saved my life about a month ago. The loud alarm woke me up in the night and wouldn't turn off. I realized that I left my stovetop on, and I assume the CO was building up throughout the night

So this is only needed if your house has natural gas correct?
No. Oil burning furnaces produce CO as well

Pretty sure this was $15-25 range when we bought one at Walmart a couple months ago.
