The best smart air quality monitors with an app
These monitors differ most in the readings they cover and how their apps connect. Start with the room concern you want to track, then check whether the app provides the connection and alerts you prefer.
Awair Element: Best for broad everyday tracking
- Temperature, humidity, CO2, VOCs and PM2.5
- Awair Home app
- Bluetooth setup and 2.4 GHz Wi-Fi
Awair Element combines five common indoor readings with app insights and tips. Its range makes it a flexible choice when you want more than a single gas or particle reading.
Pros
- Tracks five air factors
- Shows changes over time in the app
- In-app feedback and tips
Cons
- Requires 2.4 GHz Wi-Fi
- Bluetooth is needed for setup
Awair Element is the most balanced choice when you want several kinds of information in one monitor. It measures temperature, humidity, CO2, VOCs and PM2.5, then shows real-time insight and changes over time in the Awair Home app.
The app also offers feedback and tips for improving your space. That makes it a fit for someone who wants readings and some guidance in one place, rather than a device focused only on one gas.
Setup uses Bluetooth, and the monitor needs a 2.4 GHz Wi-Fi connection. Check your home network if you use a different band or keep your devices on a separate network.
Choose it for broad everyday monitoring across common air and comfort factors. If your main question is radon, the Wave Plus below includes that measurement.
Airthings Wave Plus: Best for radon and air readings
- Radon, CO2, VOCs, humidity, temperature and air pressure
- Airthings app via Bluetooth
- Battery powered
Wave Plus covers six indoor factors, including radon, and connects to the Airthings app over Bluetooth. It suits buyers who want radon readings alongside other air measurements.
Pros
- Includes radon measurement
- Tracks six indoor factors
- Battery powered
Cons
- Uses Bluetooth for app connection
- Radon readings need time to settle in a new environment
Airthings Wave Plus is the pick when radon belongs in the same view as other indoor conditions. It measures radon, CO2, VOCs, humidity, temperature and air pressure, and the Airthings app provides detailed insights over Bluetooth.
The battery-powered design can suit a spot without a nearby outlet. A color-coded visual indication is also available by waving in front of the device, while the app provides more detail.
Airthings says radon levels can fluctuate and that continuous long-term measuring is needed. It also advises allowing a 7-day settling period for sensors to adjust to a new environment, so avoid judging a new placement from an immediate reading.
Choose Wave Plus for radon plus a broad set of other readings. For a radon-only comparison, see our best radon monitors for home.
Amazon Smart Air Quality Monitor: Best for Alexa alerts and routines
- PM2.5, VOCs, carbon monoxide, humidity and temperature

- Offers suggestions tied to readings
- Does not require a base station
Cons
- Requires Amazon Sidewalk coverage
- Not a carbon monoxide alarm or detector
Ring’s monitor tracks temperature, carbon monoxide, humidity and PM2.5, then offers suggestions such as opening a window or running a purifier. It connects through Amazon Sidewalk, which is required and may have varying coverage.
No base station is required, but Sidewalk coverage still matters. Ring says this monitor is not a substitute for a carbon monoxide alarm, does not measure CO2 or radon, and has no microphone or speaker to sound an alarm.
Choose it if Sidewalk coverage is available where you plan to place it and its four readings fit your needs. If you need a dedicated CO alarm, use one designed for that purpose rather than relying on an air quality monitor.
Airthings Wave Enhance: Best for bedrooms and home offices
- CO2, VOCs, humidity, temperature and air pressure
- Also tracks noise and light
- Airthings app via Bluetooth
Wave Enhance tracks five air factors plus noise and light, with app access to readings and trends. Its combination can help you review bedroom or home-office conditions.

The battery-powered device connects to the Airthings app over Bluetooth. The app can manage notifications and offers trend views, so it can suit a room where you want to review more than one kind of condition.
Wave Enhance does not measure radon. Choose the Wave Plus if that reading matters, or consider this model when noise and light are useful alongside air measurements.
AprilAire Smart Air Quality Monitor: Best for app tips and Wi-Fi
- CO2, VOCs, PM2.5, humidity and temperature
- Healthy Air App with notifications and trends
- Wi-Fi monitor
AprilAire combines five readings with Healthy Air App explanations, tips and notifications. Its app is required for the monitor to function.
Pros
- Tracks five indoor factors
- App includes explanations and tips
- Offers notifications and trend views
Cons
- Requires the Healthy Air App
- Healthy Air Mode integration needs a compatible AprilAire Wi-Fi thermostat
AprilAire combines CO2, VOCs, PM2.5, humidity and temperature with app explanations, trend views and notifications. The Healthy Air App is required for the monitor to function, so the phone app is part of the setup rather than an optional extra.
The monitor uses Wi-Fi and provides a color status scheme for a quick glance. Its Healthy Air Mode can integrate with certain AprilAire filtration or ventilation systems, but that feature requires a compatible AprilAire Wi-Fi thermostat sold separately.
Choose it if app guidance and alerts are a priority, and you’re comfortable using the required app. It does not measure radon, so compare the Wave Plus if you need that sensor.
Airthings Wave Mini: Best for VOC-focused room checks
- VOCs, humidity and temperature
- Airthings app via Bluetooth
- Battery powered
Wave Mini focuses on VOCs, humidity and temperature, with app readings and trends. Consider it when those factors matter more than particle, CO2 or radon measurements.
Pros
- Tracks VOCs, humidity and temperature
- Battery powered
- App supports notifications and trends
Cons
- Does not measure PM2.5, CO2 or radon
- Bluetooth app connection
Airthings Wave Mini is a simpler choice for tracking VOCs, humidity and temperature. The Airthings app connects over Bluetooth and provides readings, notifications and trends.
Its narrower sensor set is the main tradeoff. Wave Mini does not cover PM2.5, CO2 or radon, so it is not a substitute for a broader monitor when you want those measurements.
Choose it when the room question centers on VOCs and comfort conditions. If you want a wider set of air readings from Airthings, look at Wave Enhance or Wave Plus.
How do you choose an app-connected air monitor?
Choose by the specific reading first, then compare app features and connectivity. A monitor with more sensors may offer a broader picture, but it can still omit the measurement you care about most.
Which readings should a smart air quality monitor include?
Match sensors to the concern. Choose a device that explicitly measures radon for radon, PM2.5 for fine particles, or CO2 for carbon dioxide; a temperature or humidity reading does not stand in for those measurements.
For a broad mix, Awair Element covers temperature, humidity, CO2, VOCs and PM2.5. The Airthings Wave Plus adds radon, while the Amazon monitor includes carbon monoxide but not CO2 or radon.
Does the app use Wi-Fi or Bluetooth?
Check the connection before you buy, since app access works differently across these models. Awair Element needs 2.4 GHz Wi-Fi after Bluetooth setup, AprilAire uses Wi-Fi, and the Airthings models connect to their app through Bluetooth.
GoveeLife H5140 uses an app for its alerts and data features, while Ring relies on Amazon Sidewalk. Consider where the monitor will sit and whether your network or phone can connect there.
Are app alerts and automation useful?
Alerts help when you want a notification after a reading crosses a set threshold or changes. Amazon supports Alexa announcements and routines with compatible devices, while GoveeLife and AprilAire describe app alerts for selected conditions.
Automation is only useful when it fits the reading and the equipment. Amazon’s monitor can activate compatible Alexa devices through routines, while GoveeLife describes connections to certain fans and humidifiers.
Compare those functions with what you already use.
Should you choose a display or app-first monitor?
A display helps you check a reading in the room, while an app can make trends and notifications easier to review. GoveeLife H5140 has a display for CO2, temperature and humidity, and Airthings Wave models use a color-coded visual indication alongside app readings.
If you mainly want remote updates or longer-term trends, pay attention to the app features instead. Awair Element tracks changes over time, and GoveeLife offers historical charts and data export.
Which smart air quality monitor should you choose?
Pick Awair Element for broad everyday tracking across five common readings. Choose Airthings Wave Plus when radon belongs in the same monitor, Amazon’s model when Alexa alerts and routines fit your home, or GoveeLife H5140 for app-based CO2 history.

Frequently asked questions
What should a smart air quality monitor measure?
Choose readings based on the question you want answered. PM2.5 tracks fine particles, CO2 can help you follow ventilation conditions, and radon requires a monitor that specifically measures radon.
Temperature, humidity and VOC readings add other context, but no one device here measures every possible indoor contaminant.
Do smart air quality monitors need Wi-Fi?
Not all of them. Awair Element uses 2.4 GHz Wi-Fi after Bluetooth setup, while Airthings Wave Plus, Wave Enhance and Wave Mini connect to their app through Bluetooth.
Check the connection type and whether your phone or home network suits it before choosing.
Can a carbon monoxide reading replace a CO alarm?
No. Ring says its monitor is not a substitute for a carbon monoxide alarm or detector, and it has no speaker to sound an alarm.
Use a dedicated CO alarm for that safety role, and treat air monitor readings as separate information.
Do all app-connected monitors show historical trends?
No. Awair Element, GoveeLife H5140, Airthings Wave Enhance and Wave Mini describe app features for changes or trends over time.
Compare each model’s app functions before buying if saved readings, exports or notifications are a key part of your decision.
