Peace of Mind in a Compact, Reliable Device

The Kidde Carbon Monoxide Detector is one of those small investments that delivers huge peace of mind. After installing it in my home, I immediately felt more secure knowing that my family is protected from something as serious—and silent—as carbon monoxide exposure.Setup was incredibly easy. It took just a few minutes to install, and the instructions were clear and straightforward. The digital display is a nice touch—it gives real-time CO levels, which adds an extra layer of reassurance beyond just an alarm.What really stands out is its reliability and thoughtful design. It has a clear, loud alert that’s hard to miss, and the test/reset button works without a hitch. I also appreciate that it’s battery-operated with a backup option, so it continues working even during power outages.In a world where safety often gets overlooked until it’s too late, this detector provides consistent, quiet protection you can depend on. If you’re looking for an easy-to-use, durable, and accurate carbon monoxide detector, Kidde is a brand you can trust—and this unit proves it.Highly recommended for any home, apartment, or even RV. It’s a small device that could make a life-saving difference.

Take it on Vacation

After seeing too many news stories of people getting sick and even dying while traveling from carbon monoxide I got this. I carry it in my carry on bg. I pit it on a counter or table in our hotel room or AirBnB. Nice sense of security.

Replace every 10 years

The mounting frame is identical to the one they had 10 years ago, so this is an easy choice. Pop the old one off, write the date 10 years out on the new one, stick it up on the wall on the old bracket. It's that simple.

NOT NEW: Kidde ships from Amazon with already 8% life gone.

Fine design/manufacturing, and as typical for CO detectors, suicides after exactly 10 years...yet manufacturer Kidde shipped from Amazon EVEN AFTER "+7k bought in past month" was ALREADY 10 months old, 8% life gone, 92% life left. Sales with more than 3 months consumed is neither fresh nor necessary. Bad Kidde.

A traditional CO Detetor

Like its digital display to indicate the exact CO value. It seems it is hard to test the CO sensor but only to trust its brand. Easy to install. Alarm is loud enough. Works well. The product's date of MFG is 2024 Aug 12 so it should be good for the next 9 years.

Reliable and easy to use

Runs on AA batteries, has clear LEDs, and the test/reset button works well. Loud enough to get your attention. Super easy setup and small enough to take when traveling. Feels like a smart, no-hassle safety buy.

Reaches End of Life After 10 Years Which is Fine With Me

This is a great detector, easy to install. Note that after 10 years it will give an alarm, and the screen will read end for end of life. That's not because of the batteries, but the sensor. In my case the detector I ordered and installed in Feb 2015 had this alarm in Apr 2025. Fortunately I was able to slide the old detector body off its base screwed to the wall and slide the new detector body on. Only issue I had was after about 8 years it beeped which was caused by the AA alkaline batteries corroding so I had to clean the terminals with DeoxIT and install new batteries. After that no issues to end of life alarm. Looking forward to another 10 years of service from this one.

I had to replace the original set because they were 10 years old

I used to work on a fire department and CO (carbon monoxide) alarms that just beeped were the bane of our existence because we often had no idea if it was a false alarm if our gas meters showed no problem. Having a detector with a digital readout removes that uncertainty.Yes, we have seen the CO level above zero because we keep one in the RV and there was a problem with the propane RV fridge. The CO level reached 79 PPM at one point. The "beep only" factory CO alarm just stayed silent.Since the first set lasted 10 years until they expired I figured it was a good idea to buy the same ones again. :)
