How we chose the best air quality monitor for home use
The best home air quality monitor is the one that measures the pollutants and conditions you care about, with a display or app you can use. We compared the sensor lists, connection needs, power details, and alerts provided for these models.
A broader sensor list can be helpful, but it does not make every reading equally important to every household. Radon, PM2.5, CO2, VOCs, temperature, and humidity each answer different questions, so weigh the readings you expect to check.
We also looked at practical limits. Some monitors require a specific app or Wi-Fi band, some rely on a particular smart-home system, and portable battery operation varies from a few hours to multiple years.
Our score weighs specs, features, and buyer feedback against what you're shopping for.

How should you choose a home air quality monitor?
Choose a home air quality monitor by the reading you need to act on, then check how you'll view the data and power the device. A long feature list matters only when it covers your actual concern.
For fine particles from cooking, smoke, or outdoor pollution, look for a PM2.5 reading. Our guide to the difference between PM2.5 and PM10 explains what the two particle labels represent.
If your main question is ventilation, a CO2-focused monitor may be enough. CO2 does not tell you about radon, particles, or most VOCs, so don't treat one number as an overall air quality score.
For chemical readings, compare what each model measures. VOC or TVOC readings, and a separate formaldehyde reading, are not interchangeable; see VOC vs TVOC on a monitor for the distinction.
Do you need radon, carbon monoxide, or both?
Radon and carbon monoxide are different concerns, and a home air monitor that measures one may not measure the other. Check the sensor list and keep dedicated safety devices where required.
View Plus and Wave Plus include radon readings, while the Amazon and Ring monitors include carbon monoxide readings. The Amazon and Ring product information specifically says their CO readings are not certified CO alarms or detectors.
If radon is your priority, compare these picks with the best radon monitors for home. For carbon monoxide safety, use a proper CO alarm rather than relying on an air quality monitor.
Are smart air quality monitors worth choosing?
A smart air quality monitor is useful when you want alerts, remote readings, or trends in an app. Check whether the model needs a specific Wi-Fi band, account, smart-home platform, or internet connection.
View Plus requires the Airthings app, an account, and internet access. Awair Element requires Bluetooth for setup and 2.4 GHz Wi-Fi, while Ring requires Amazon Sidewalk.
For a screen-first setup, Qingping provides readings on a touchscreen, and the GoveeLife H5140 shows CO2, temperature, and humidity on its display. Consider where you'll put the monitor and whether a cable, app, or smart-home link fits that room.
Which best air quality monitor for home should you choose?
Choose the Airthings View Plus if you want one monitor for radon, PM2.5, CO2, VOCs, humidity, temperature, and air pressure. Choose Awair Element for app-based trends, Amazon Smart Air Quality Monitor for Alexa routines, or GoveeLife H5140 for a focused CO2 display.
If you need more particle detail, consider BREATHE Airmonitor Plus Gen 2 or Qingping Air Quality Monitor Gen 2. For radon-specific choices, see our home radon monitor guide, then match the sensor set to the question you need answered.

Frequently asked questions
What should a home air quality monitor measure?
Choose readings based on the question you want answered. PM2.5 helps track fine particles, CO2 can show changes tied to occupancy and ventilation, and VOC readings can show changes in some airborne chemicals.
Radon is a separate concern, so choose a monitor that specifically includes radon if you want continuous radon readings.
Do air quality monitors measure carbon monoxide?
Some do, including the Amazon Smart Air Quality Monitor and Ring Air Quality Monitor. Their CO readings do not make them substitutes for a certified carbon monoxide alarm.
Keep a proper CO alarm for safety, and use an air monitor for the readings and features it was designed to provide.
Can one monitor measure radon and PM2.5?
Yes. Airthings View Plus measures both radon and PM2.5, along with CO2, VOCs, humidity, temperature, and air pressure.
Check the exact sensor list before choosing a monitor because models with similar names can measure different things.
Does a CO2 monitor measure overall air quality?
A CO2 reading covers carbon dioxide, which can help you notice changes in a room as people use it and ventilation changes. It does not measure particles, radon, or most other pollutants by itself.
For broader coverage, choose a monitor with the other readings you need.
Are home air quality monitors accurate?
Accuracy depends on the sensor, setup, room conditions, and what the monitor measures. A device that estimates one reading cannot answer every air quality question.
See our guide to how accurate home air quality monitors are and compare each model's sensor claims with your needs.
