The Kidde COPDLQW is a smart plug-in CO alarm that adds indoor air quality monitoring — temperature, relative humidity, and Total Volatile Organic Compounds (TVOCs) — to CO detection and remote smartphone alerts. It is the most capable unit in the Kidde plug-in CO lineup for households that want comprehensive air safety data from a single connected device.
Construction and Design
The COPDLQW plugs into a standard 120V outlet via a rotating plug that adjusts 90 degrees. AA backup batteries maintain CO detection during power outages. The 2.4 GHz Wi-Fi radio connects to the Kidde mobile app for remote monitoring, alerts, and status checks. A backlit digital display shows CO concentration and air quality data on button press. The unit supports Kidde's optional Advanced Home Health subscription for personalized air quality insights and trend analysis, though the subscription is not required for basic app functionality.
Detection and Monitoring Performance
CO detection meets UL 2034 thresholds with added low-level alerts for sub-threshold concentrations. The indoor air quality sensors measure temperature (°F/°C), relative humidity (%), and TVOCs (volatile organic compounds from paints, adhesives, cleaning products, and off-gassing materials). App integration delivers real-time alerts for CO events and air quality threshold notifications. The TVOC sensor provides an index-based reading rather than compound-specific identification; it indicates elevated organic compound presence but does not identify the specific source compound.
Strengths
- Combines CO alarm, low-level CO detection, and air quality monitoring in a single unit
- Real-time smartphone alerts for CO events from anywhere with cellular or Wi-Fi
- TVOC, temperature, and humidity monitoring adds context for indoor air quality management
- Low-level CO alerts protect health-sensitive household members
- AC-powered with battery backup for continuous protection
Limitations
- Requires 2.4 GHz Wi-Fi — 5 GHz-only configurations require router reconfiguration
- TVOC reading is an index, not compound-specific identification — source investigation requires separate instruments
- No explosive gas (natural gas/propane) detection; the COPDLG covers combustible gases
- Advanced Home Health subscription adds recurring cost for enhanced insights
Recommended Applications
The COPDLQW suits primary living areas, bedrooms, and nurseries where comprehensive air quality awareness is a priority in addition to CO safety. It is appropriate for households with health-sensitive occupants, those in areas with known air quality concerns, and property managers who require remote CO monitoring. For explosive gas coverage, a separate COPDLG should be installed in gas appliance areas.
Verdict
The Kidde COPDLQW is the highest-specification plug-in unit in the standard Kidde CO lineup — combining CO detection, low-level alerts, smart connectivity, and indoor air quality monitoring. For households committed to comprehensive home air safety monitoring through a single connected device, it provides meaningful capability not available in any other single Kidde unit. The absence of explosive gas detection means it complements rather than replaces the COPDLG in gas-equipped homes.

An excellent product to not only protect yourself but to learn about air quality
This carbon monoxide detector and indoor air quality monitor is an excellent product. Installation was very straightforward; one simply plugs it into an outlet and downloads the accompanying application to a smartphone or device. It features a very clear display, and the app provides comprehensive information regarding your home's air quality, which is truly beneficial. Not only does it offer peace of mind, but it also assists in improving the overall quality of the air breathed daily. We acquired this as a suitable replacement for our previous unit and are highly satisfied with it compared to our old monitor. Mounting was effortless, and there were no complicated instructions to follow to get it operational. The device includes a backup battery, which is a thoughtful feature in the event of a power outage, providing a significant amount of battery life until power is restored. Should a replacement be necessary in the future, it would be a simple process of swapping it out for a new one, which greatly simplifies maintaining the protection of one's home and self. Overall, this is a fantastic product that has provided valuable insights into aspects I hadn't previously considered. I truly appreciate it and would highly recommend it.

Device does not fit into a standard US electric outlet.
Beware. Plug did not fit into a standard US electric outlet. The device was not useable in my home.I have returned the device as directed at the Amazon store in Columbus Ohio but no refund issued. No communication at all that Amazon or Kidde even received the defective device.

Works great with slight annoyances
The Kidde Smart Carbon Monoxide Detector & Indoor Air Quality Monitor feels like a modern upgrade over the basic detectors most of us grew up with. Setup itself was easy, just plug it in, connect it to your Wi-Fi, and the app walks you through the process pretty quickly. I really like getting real-time alerts on my phone for CO issues or changes in air quality instead of relying only on an alarm going off in the house.The extra air quality features ended up being more useful than I expected. It tracks things like humidity and VOCs, so it’s interesting seeing how cooking, cleaning products, or even just daily activity affect the air indoors. The rotating plug is a small but genuinely thoughtful design choice, and the battery backup adds some peace of mind during outages. The alarm is loud, and overall the unit feels solid and reliable, which is exactly what you want from a safety device.My main complaint is the app/account side of things. Having to create an account for a carbon monoxide detector is annoying, and some features being locked behind a subscription feels unnecessary for a product already at this price point. The display also isn’t the easiest to read in a low outlet. Still, the smart alerts and added monitoring features make this feel much more useful than a standard detector.

Good Smart CO Detector - Best If You Actually Want the App Features
I bought this because I wanted more than a basic carbon monoxide alarm. The main benefit is that it plugs into the wall, has battery backup, and can send phone notifications, which gives more peace of mind when I am away and my pets are hpme. Setup through the app was reasonably straightforward, though like many smart home devices it works best if you already understand 2.4 GHz Wi-Fi setup.The display is useful because it lets you see status information without guessing from lights or chirps. The alarm is loud, and the unit feels like a serious safety device rather than a gadget. I also like having indoor air quality information in the same device, especially since it gives a little more context about what is happening in the room beyond just CO detection.There are a few tradeoffs. It is much more expensive than a simple standalone CO detector, so the value depends on whether you really want app alerts and air-quality monitoring. Also, some of the more detailed air-quality features appear tied to the app ecosystem, and I would prefer as much functionality as possible to be available without ongoing extras.Overall, this is a solid option if you want a plug-in CO detector with smart notifications and basic air-quality awareness. If all you need is a simple alarm, it may be more than necessary, but for remote alerts and added monitoring, it is a worthwhile upgrade.

Nifty device
The Kidde plug-in Wi-Fi enabled carbon monoxide detector is a great choice for many reasons. First, I appreciate the additional safety provided by AC power with battery backup. The battery is going to keep it running when electricity is knocked out, though of course you won’t get remote alerts if your WiFi is down. It’s a nice looking unit, compact and modern. The display is easily readable, but depending on where you plug it in, maybe not easy to access. And the reliability of a brand name device is definitely a plus.What most impressed me about it was the ability to access it through the app. You get instant reads of temperature, humidity, and air quality. They also have a subscription service for additional data, which we are not doing. Overall, while this is more expensive than a basic CO alarm, I really like the connected aspect of it. Very cool.
