The Ring Air Quality Monitor tracks temperature, humidity, carbon monoxide and PM2.5, then offers suggestions such as opening a window or running a purifier. It may suit a home already using Ring or Amazon Sidewalk, but it does not measure CO2 or radon.
Its key limit matters: this device can register carbon monoxide, but it is not a carbon monoxide alarm or detector and cannot sound an alarm. Keep a separate, approved CO alarm for safety.
Ring Air Quality Monitor: what you get
The Ring Air Quality Monitor covers four indoor conditions: temperature, humidity, carbon monoxide and PM2.5. It connects through Amazon Sidewalk, with no separate base station required, though coverage may vary.
Ring Air Quality Monitor: Best for Ring and Sidewalk homes
- Temperature
- Humidity
- Carbon monoxide
- PM2.5
- Amazon Sidewalk connectivity
A focused indoor monitor for people who want temperature, humidity, carbon monoxide and PM2.5 readings with smart suggestions. It needs Amazon Sidewalk and does not measure CO2 or radon.
Pros
- Tracks four indoor conditions
- Offers suggestions such as opening a window or running a purifier
- No separate base station required
Cons
- Requires Amazon Sidewalk, and coverage may vary
- Does not measure CO2 or radon
- Not a substitute for a carbon monoxide alarm
Ring also offers suggestions when conditions may call for an action, such as opening a window, running a purifier or servicing an appliance. These prompts can help you decide what to check, but they don't diagnose the source of a reading.
Who should consider the Ring monitor?
Consider it if you want those four readings and already use, or can access, Amazon Sidewalk connectivity. It is less suitable if your main goal is CO2 tracking, radon monitoring or an audible carbon monoxide warning.
A home monitor only reports what its sensors are designed to measure. Our guide to how air quality monitors work explains why one device may track some pollutants while leaving others out.
What does it measure, and what does it miss?
The Ring monitor measures carbon monoxide, not carbon dioxide. The similar names refer to different gases, so check the exact label when deciding which reading you need.
| Reading or feature | Ring Air Quality Monitor |
|---|---|
| Temperature | Yes |
| Humidity | Yes |
| PM2.5 | Yes |
| Carbon monoxide | Registers levels; not a certified alarm or detector |
| Carbon dioxide | No |
| Radon | No |
| Connectivity | Amazon Sidewalk required; coverage may vary |
| Audible alarm | No microphone or speaker |
PM2.5 refers to fine particles in the air. For a plain explanation of that reading, see what PM2.5 means on an air quality monitor.
Carbon monoxide and carbon dioxide readings answer different questions. If you need a ventilation-focused reading, compare models that explicitly measure CO2, such as the GoveeLife CO2 monitor or our guide to CO2 monitors for home use.
Is the Ring monitor a carbon monoxide alarm?
No. Ring says the monitor is not a substitute for a carbon monoxide alarm and is not certified as a CO alarm or detector.
It also has no microphone or speaker to sound an alarm.
Use a separate, approved CO alarm in the locations and manner its manufacturer specifies. A monitor that registers a gas level can provide useful context, but it does not replace equipment designed and certified to warn you.
Don't use the Ring device as the only way to learn about carbon monoxide. If a dedicated alarm sounds, follow its instructions and contact emergency services as appropriate.
Does it need Amazon Sidewalk?
Yes, the Ring monitor needs Amazon Sidewalk to connect, although it does not require a separate base station. Ring notes that Sidewalk coverage may vary, so connectivity is a practical part of the buying decision.
Think about the room where you plan to place it and whether your home has usable Sidewalk coverage there. If you can't rely on that connection, compare an option built around the smart home system you already use.
The Amazon Smart Air Quality Monitor may fit better if Alexa app details, alerts and routines matter more to you. It measures PM2.5, VOCs, carbon monoxide, humidity and temperature, and works with compatible Alexa devices.
Ring vs Amazon Smart Air Quality Monitor
Choose Ring for its connection to a Ring or Sidewalk setup, and choose Amazon's monitor if you want VOC readings and Alexa routines. Both measure PM2.5, carbon monoxide, humidity and temperature; neither measures CO2 or radon.
Amazon Smart Air Quality Monitor: Best for Alexa air quality routines
- PM2.5
- VOCs
- Carbon monoxide
- Humidity
- Temperature
A broader Alexa-connected option that tracks five factors and can trigger compatible device routines. Choose it if VOC tracking and Alexa app details matter more than Ring integration.
Pros
- Tracks VOCs in addition to PM2.5 and carbon monoxide
- Shows a color-coded LED and an app air quality score
- Can send alerts and run compatible Alexa routines
Cons
- Does not measure CO2 or radon
- Smart features depend on Alexa and compatible devices
Amazon's monitor provides a color-coded LED, an air quality score in the Alexa app, phone notifications or Echo announcements, and routines for compatible devices. Those features make it the broader match for an Alexa-centered home.
Ring's suggestions focus on possible actions, including opening a window, running a purifier or servicing an appliance. Compare the devices by the readings and smart home features you expect to use, rather than assuming the shared readings make them interchangeable.
What should you compare before buying?
Start with the specific reading you need, then check connectivity and the kind of alert you expect. These choices matter more than a general label like “air quality monitor.”
- For fine particles, check that the device measures PM2.5.
- For volatile organic compounds, look for VOC or TVOC measurement.
- For ventilation, choose a monitor that measures CO2.
- For carbon monoxide safety, use a certified CO alarm.
- For radon, choose a radon monitor designed for that purpose.
- For smart features, confirm the device works with your home system and has the connection it requires.
A device may cover several readings without measuring all of them. Our guides to choosing an air quality meter and reading monitor numbers can help you match a feature list to your goal.
When a CO2 monitor makes more sense
Choose a CO2 monitor if you want to watch carbon dioxide levels as part of managing ventilation. The Ring monitor does not measure CO2, so it can't provide that reading.
GoveeLife H5140 CO2 Monitor: Best for direct CO2 readings
- CO2
- Temperature
- Humidity
- Display
- App alerts
A dedicated CO2 monitor with temperature and humidity readings, a display, app alerts and a buzzer. It suits people focused on ventilation and CO2 rather than carbon monoxide or particle readings.
Pros
- Shows CO2, temperature and humidity
- Offers buzzer and app alerts
- Tracks historical data in the app
Cons
- Does not measure carbon monoxide or PM2.5
- Uses AC power for continuous monitoring
The GoveeLife H5140 displays CO2, temperature and humidity, and offers a buzzer, app notifications and email reports when customizable thresholds are exceeded. It uses AC power for continuous monitoring and supports historical data tracking in its app.
A purifier won't lower CO2, so a high reading calls for attention to fresh air and ventilation. The GoveeLife product information suggests opening windows for cross-ventilation, using exhaust fans or installing a fresh-air system.
For more on what CO2 monitors can tell you, read our home CO2 monitor guide. If you need to understand the sensor type, see what an NDIR sensor is.
How should you use readings and suggestions?
Treat readings as signals to investigate, not diagnoses of a problem. A suggested action can prompt you to check ventilation, a nearby source or an appliance, but a single measurement may not explain why the reading changed.
Note when the reading changes and what was happening in the room. Cooking, cleaning, open windows and room occupancy can all be useful context when you compare readings over time.
The Ring device tracks temperature and humidity as well as PM2.5 and carbon monoxide. For help interpreting common readings, see how to read an air quality monitor.
Is the Ring Air Quality Monitor worth considering?
The Ring Air Quality Monitor is a reasonable fit for Ring or Sidewalk homes that want temperature, humidity, PM2.5 and carbon monoxide readings with action suggestions. Its limits are clear: no CO2 or radon reading, variable Sidewalk coverage, and no audible CO alarm.
Pick Ring if its readings and Sidewalk connection match your home. Pick the Amazon Smart Air Quality Monitor for Alexa routines and VOC measurement, or the GoveeLife H5140 when CO2 is the reading you need.
