Safe, convenient and durable!
on May 2, 2026

[This review was collected as part of a promotion.] I am very impressed with the Kidde carbon monoxide alarm and air quality monitor system! The setup made it incredibly easy to install in my home. Overall it’s small and seem to be very durable. I just opened the box and followed the simple steps to install it. From what I can tell, the air quality monitor is extremely accurate.
I am highly satisfied with the product and definitely recommend it to anyone wanting some additional safety measures in their home!

Simple & convenient
on May 1, 2026
Posted by: JessT
[This review was collected as part of a promotion.] Quick and very simple setup. It literally just plugs right in! You’ll have to download the Kidde app to complete setup. The app allows you to add and manage multiple Kidde products to your “Home”. You will need WiFi for it to function properly. There are additional features that you can subscribe to and pay for, but they’re not necessary for basic functionality. Not too big or bulky, which was a concern of mine. Love that I can check our ranges from anywhere via the app!

Thanks for sharing your experience with us, Jess! We are pleased to hear that installation and connectivity were seamless, and that the in-app notifications create an extra sense of peace of mind. To help ensure the alarm remains working properly, we recommend testing and cleaning it regularly. We appreciate you choosing Kidde!

A Modern Life Saver Smoke and Carbon Monoxide Dete
on April 30, 2026
Posted by: VincentL
[This review was collected as part of a promotion.] I was tired of having the old school smoke detectors and carbon monoxide detectors. Finally upgraded to a more modern and app compatible detector! It is super simple to setup, with nice informational displays. Simple battery setup and discreet!
Response from KiddeBy Kidde Team, May 1, 2026
Thank you for sharing this with us. We’re glad to hear the upgrade has been a smooth one and that the app and display are working well for you. Since carbon monoxide is invisible and odorless, having a CO Alarm that’s easy to check can make a big difference.

Easy install, just pull the tab for the battery compartment and plug in to any standard wall socket. Can even download the app and add to your Google home to receive alerts and have peace of mind where ever you are. A must need to have in any home. A trusted brand that is both accurate and reliable.

As easy as connecting a device to WiFi
on April 29, 2026
Posted by: AlexaW
[This review was collected as part of a promotion.] This was incredibly easy to set up. First, I pulled the tab in the battery area. Then I put the batteries inside. The alarm immediately beeped. I then scanned the QR Code on the back of the device, and plugged it in. From there it was as easy as downloading the app, and connecting it to WiFi. I was not expecting it to tell me the temperature and humidity within my room as well, and it will alert me if the room is at risk for mold growing. This is amazing, and something I will absolutely recommend to my close loved ones. The beep is loud enough to be heard around my 2400 square foot home. The display is easy to read.

Easy to use and well made!
on April 28, 2026
Posted by: JamesA
[This review was collected as part of a promotion.] I received this product in exchange for my honest review. Super excited for this one as I’ve been eyeing something to test air quality in our house for a bit. We have allergy sufferers in the house (me especially) so this was perfect, now we can see if our indoor air quality is contributing to our issues. Plus it protects against CO2. Overall, super easy to set up and get running. Design is sleek so it doesn’t stick out against the wall. The app was simple, and easy to use. Entire process was a breeze and we’re already using it! Seems well made, and should hold up over time. Really happy with this and would highly recommend it for others homes as well.
