Kidde COPDW Smart WiFi Carbon Monoxide Alarm, Plug-In with Low-Level CO Alert Overview
The Kidde COPDW smart WiFi carbon monoxide alarm is a plug-in residential CO alarm with app connectivity. It uses an electrochemical CO sensor, plugs into a 120V AC outlet with a rotating plug and two AA backup batteries, and connects over 2.4GHz WiFi to send real-time alerts through the Kidde app, with Amazon Alexa and Google Home support. It gives an earlier low-level CO alert starting at 30 ppm and a separate alarm at 70 ppm.
As the Kidde COPDW, this smart WiFi CO alarm is the CO-focused member of Kidde's smart lineup. As a plug-in CO detector with app it pushes notifications when you are away, and as a low-level CO alarm it warns earlier at 30 ppm. As a WiFi carbon monoxide detector it is tested to UL 2034 5th Edition and ETL Listed.
This is a CO alarm, not a smoke or gas detector, and unlike the air-quality version it does not track temperature, humidity, or TVOC. Compare it against other smart CO alarms, including the air-quality Kidde COPDLQW, the wider Kidde CO alarms range, and the carbon monoxide alarms and detectors category before ordering.
What This Alarm Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Connected home CO protection | Purpose-built | WiFi and the Kidde app push 24/7 notifications. |
| Protecting sensitive people | Strong | Low-level CO alert starts earlier at 30 ppm. |
| Outage-resilient protection | Strong | AA backup keeps it running in a power cut. |
| Budget smart CO alarm | Strong | CO-only keeps the price below the air-quality model. |
| Air quality / smoke / gas | Not suitable | Choose an air-quality, smoke, or gas model for those. |
A carbon monoxide alarm is a life-safety device, so treat any CO alarm as an emergency: get to fresh air, call for help, and have the source fixed by a professional. This is a residential early-warning alarm; it is not built for occupational settings where carbon monoxide can climb to IDLH concentrations that demand industrial gas-detection instruments and rescue procedures, so use the right tool for each environment. Install and place it per the Kidde manual and local codes, keep it plugged in with fresh AA backup batteries, understand that the low-level alert at 30 ppm is an early warning rather than a reason to panic, and replace the unit at end of life.

How It Compares
The COPDW is Kidde's CO-only smart alarm. Weigh it against the alternatives before ordering:
| Option | Detects | Air quality | Best for |
|---|---|---|---|
| Kidde COPDW (this page) | CO | No | Budget smart CO with app alerts |
| Kidde COPDLQW | CO | Yes (temp, humidity, TVOC) | Smart CO plus air-quality trends |
| CO + explosive gas alarm | CO + natural gas + propane | No | Homes with gas appliances |
Choose the COPDW for connected CO protection at a lower price, the COPDLQW if you want air-quality data, or a CO and explosive-gas alarm for gas appliances. See our best carbon monoxide detectors guide, the best garage CO detector guide, and, for work settings, the best industrial CO monitor guide.

Frequently Asked Questions
Does the COPDW include an air quality monitor?
No. The COPDW is a smart CO alarm only; it does not monitor temperature, humidity, or TVOC air quality. If you want air-quality monitoring alongside CO, choose the Kidde COPDLQW, which adds those readings for a higher price.
What is the low-level CO alert?
The COPDW gives an earlier low-level alert starting at 30 ppm, ahead of the standard 70 ppm alarm point, which can help protect people who are more sensitive to carbon monoxide. It uses distinct signaling for the low-level and the higher-level alarm.
How does it connect and notify me?
It connects over 2.4GHz WiFi and sends real-time alerts through the Kidde app whether you are home or away. It also works with Amazon Alexa and Google Home and select iPhone and Android devices for notifications and status.
How is it powered?
It plugs into a 120V AC outlet and includes two AA backup batteries for coverage during a power outage. The rotating plug fits vertical or horizontal outlets so the display stays readable.
Is it certified?
Yes. Kidde states the COPDW is tested to UL 2034 5th Edition, the current CO alarm standard, and is ETL Listed, with a 10-year limited warranty. Confirm current markings on the product packaging.
Is this a smoke alarm too?
No. The COPDW detects carbon monoxide only; it is not a smoke alarm. For fire protection, add a dedicated smoke alarm or a combination smoke and CO alarm elsewhere in the home.
Does it detect natural gas or propane?
No. It detects carbon monoxide only, not explosive gas. If you need to detect natural gas or propane along with CO, choose a combination CO and explosive-gas alarm instead.
How is the COPDW different from the COPDLQW?
Both are plug-in smart CO alarms with AA backup and WiFi. The COPDLQW adds an indoor air quality monitor for temperature, humidity, and TVOC, while the COPDW is a CO-only smart alarm at a lower price. Pick based on whether you want air-quality data.
Does it work without the app?
Yes. It functions as a standalone CO alarm with a local horn and backlit display. The app and voice assistants add remote alerts, but the core carbon monoxide protection does not depend on your phone or WiFi.
How loud is it?
It sounds an 85-decibel alarm when carbon monoxide is detected, which is designed to be heard through a home, and it shows the CO reading on a backlit digital display with LED indicators.
Is it a replacement for an industrial CO monitor?
No. It is a residential early-warning alarm. Workplaces where carbon monoxide can reach high, hazardous levels need occupational gas-detection instruments and procedures, not a home alarm.
What should I do when it alarms?
Treat a CO alarm as an emergency: move everyone to fresh air immediately, call emergency services or your gas utility, and do not re-enter until it is cleared. Then have the CO source found and fixed by a qualified professional.
