Safety first! This bestselling carbon monoxide detector is $17 for 4th of July

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 you replaced yours, it’s probably time for a new one. My recommendation? The No. 1 bestselling Kidde Carbon Monoxide Detector, which is portable enough to travel with. Plus, it’s currently marked down for Amazon’s 4th of July sale.

Why is it a good deal? 💰

You can’t put a price on safety, but $17 is extremely reasonable for a product that could literally save lives. This isn’t the absolute lowest price we’ve seen on this model, but it’s just about as low as we’ve seen it dip in the past year — nearly 40% off.

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 whether 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 a little extreme, but I’d rather err on the side of caution. Since this portable model is quite compact, I plan on keeping it in my suitcase juuust in case. After all, vacation is much more enjoyable with some peace of mind!

At under half a pound and 5 inches wide, the Kidde makes a smart travel mate, but it’s ideal for at-home use as well. It calls for two AA batteries (included) and can be mounted to a wall or placed on a table or other flat surface. To ensure it’s working, press the test button (it’s loud). The green light means it’s on, but a red light and beeping means you should go outside immediately.

This compact carbon monoxide detector comes with a 10-year limited manufacturer 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’ll keep working during power outages.)

What reviewers say 💬

Over 25,000 Amazon customers are sleeping easier with the Kidde Carbon Monoxide Detector.

Pros 👍

“This product possibly saved my and the lives of my family,” shared one relieved shopper. “I decided to replace the ones I had mounted from several years ago; two weeks after and at 4 a.m., it began alerting near my boiler room. After having an army of plumbers come in, it was found that there was a CO leak from my old boiler that was not persistent, so it wasn’t at a level to set off my old alarm. It was explained that the issue was progressive and would have gotten worse, so the early alerting gave me an opportunity 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 to Cozumel with us,” shared a savvy jetsetter. “It was very lightweight and easy to pack. I highly recommend taking one when traveling abroad. I don’t think you can ever be too safe.”

“My last one needed to be replaced after it started beeping due to age,” explained a repeat buyer. “Luckily, it was of the same brand, so this new detector went right back onto the same backplate, with no need to install the new one. Easy as pie. CO detectors are a must-have for anyone who has fossil fuel-based utilities, including a furnace, boiler, water heater or stove, and these are a great option.

Cons 👎

“One downside is that it does not have a screen,” wrote an otherwise thankful reviewer, “so at first I was hesitant whether it was actually beeping from detecting CO or low battery. … This product literally saved the lives of me and my two toddlers! We had a leak of carbon monoxide in our home from our standby generator, and by the time the fire department arrived and tested, they said the levels in our attic leaking down into our home from our generator were extremely dangerously high. Cannot explain in words how grateful I am for this quality product.”

“A must-have!” exclaimed a final fan. “I like that you can either hook it up on a wall or you can leave it on a different surface.” Their one note? “I wish it had a plug-in option.” (Psst: I also have this plug-in model in my house, though it’s less travel-friendly.)
