The Kidde Smart Carbon Monoxide Detector & Indoor Air Quality Monitor uses electrochemical sensor technology to detect poisonous CO gas in your home and alert you by sounding an 85-decibel alarm with a voice alert announcing “Warning! Carbon Monoxide!”. The Kidde carbon monoxide alarm plugs into a standard, 120V AC power outlet and provides battery backup in the event of a power failure. The lithium battery backup lasts the full 10-year life of the alarm, so you’ll have the benefit of never having to replace a battery. Up-to-date, real-time notifications are provided through the Kidde app, so your family & friends – even the pet sitter – can monitor your home’s air quality & receive alerts to CO presence, high humidity levels that can lead to mold, unexpected high or low temperatures, or Total Volatile Organic Compounds (TVOCs). Setup is easy: simply download the Kidde app, scan the QR code at the back of the CO alarm, & plug the unit into your wall outlet. You can also use voice commands to check the connection & status of carbon monoxide or air quality by pairing it with your Amazon Alexa, Google Home, and select iPhone & Android smart devices. A digital display screen on the plug-in carbon monoxide alarm provides real-time information on the status of indoor air quality and carbon monoxide levels. Two buttons are provided for easy accessibility: the Test-Hush temporarily silences nuisance alarms, tests if the unit is operating properly, and silences a low battery or end-of-life chirp (up to 24 hours at a time for a maximum of 7 days), while the Peak Level Memory Button records the highest CO level reached since the button was last pressed. Install a smoke detector on each level of your home and inside and outside each bedroom. UL Certified with a 10-year limited warranty (not a battery performance claim).

Customers report mixed experiences with the carbon monoxide detector’s accuracy, with some saying it works as expected while others note it provides inaccurate readings. Moreover, the connectivity is problematic as the device never stays connected to WiFi, and setup instructions are found to be useless. Additionally, the air quality monitoring receives mixed feedback, with some appreciating the humidity and CO sensor while others report it reads air quality as “bad.” Customers find the functionality positive, with one mentioning it’s essential for family safety and health. However, the product receives negative feedback for its battery life, continuously indicating low battery, and value for money, with customers describing it as an expensive mistake.
