My Airbnb didn’t have a carbon monoxide detector, so I bought this portable one – it’s down to $18 at Amazon

For better or worse, the phrase “better safe than sorry” has become my motto as an adult. That means, among other things, carbon monoxide detectors on every floor – and they have to work! If you can’t remember the last time yours was replaced, it’s probably time for a new one. My suggestion? This No. 1 best-selling Kidde Carbon Monoxide Detector. 1, which is portable enough to travel with. Plus, it’s currently marked down at Amazon.

Thousands of Amazon shoppers swear by this little savior.

Why is it a good deal?

You can’t put a price on safety, but $18 is pretty reasonable for a product that could save lives. This isn’t the absolute lowest price we’ve seen for this model, but it’s close to the best price we’ve seen in the last year.

Why do I need this?

True story: Because I’m a safety obsessive, I check every hotel room and Airbnb I stay in to see if there’s a carbon monoxide detector. Recently, I was at an Airbnb that only had smoke detectors. So what did I do? I went out and bought the Kidde Carbon Monoxide Detector.

It might seem like a lot, but I’d better be careful. Since this portable model is quite compact, I plan to keep it in my suitcase yuuust in case. After all, holidays are much more enjoyable with some peace of mind!

At less than half a pound and 5 inches wide, the Kidde makes a smart travel companion, but is also suitable for home use. It requires two AA batteries (included) and can be mounted on a wall or placed on a table or other flat surface. To make sure it’s working, press the test button (it’s loud). The green light means it’s on, but a red light and pulse means you should go outside immediately.

This compact carbon monoxide detector comes with a 10-year limited manufacturer’s warranty, but you’ll want to make sure the batteries are always in working order. (Speaking of batteries: Because it doesn’t plug into an outlet, it will keep working during a power outage.)

What critics say

More than 24,000 Amazon customers are sleeping easier with the Kidde Carbon Monoxide Detector.

“This product may have saved my life and the lives of my family,” shared one relieved shopper. “I decided to replace the ones I had been wearing since several years ago; two weeks later and at 4 am, it started to sound near my boiler room. After an army of plumbers arrived, it was discovered that there was a CO leak from my old boiler that wasn’t continuous, so it wasn’t at a level to set off my old alarm It was explained that the issue was progressing and would get worse, so gave the early warning allowed me to address the problem before. it got to a point where it could have caused real physical damage or possibly much worse.”

“​​​​​​​We got this to take with us to Cozumel,” shared a shrewd jetliner. “It was very light and easy to pack. I highly recommend taking one when traveling abroad. I don’t think you can ever be too safe.”

“Must be!” exclaimed a final fan. “I like that you can hang it up on a wall or you can leave it on another surface.” Their only note? “I wish it had a plug-in option.” (Psst: I also have this plug-in model at home, though not as travel-friendly.)

While we’re at it, do you need a new smoke detector?

Amazon

There is no such thing as too many smoke detectors. At $10 each, these battery-operated essentials should be a fixture in your home.

“Works well and VERY sensitive to ANY smoke!” wrote a happy user. “I was making toast and the sensor in my hall down from my kitchen went off, no smoke was even visible! And it was super loud. But I like that! Only happened once, but it’s good I still think it was very high and works well.”
