Our Top Picks

Airthings 2960 View Plus Radon Air Quality Monitor

Airthings 2960 View Plus Radon & Air Quality Monitor


What We Like
  • Comprehensive monitoring

  • Sleek design

  • Smartphone and WiFi-compatible

  • Can be a hub for multiple monitors

  • Monitors radon

What We Don't Like
  • Expensive

  • Batteries will need to be replaced

With this air quality monitor, you can keep tabs on major factors such as particulate matter, carbon dioxide, radon, VOCs, humidity, temperature, air pressure, and pollen. If there are any concerns, especially with radon, which can be hazardous, it will send alerts directly to your smartphone. It also has a helpful display on the unit itself. Just wave your hand in front of the unit to show your custom display readings.

The View Plus can serve as a hub for other Airthings monitors in your home. It connects to your WiFi network to receive and transmit information. The setup process is straightforward, and no wiring is required. You can choose to hang it on a wall or place it on a shelf or table. With the app, you can create alerts and generate reports to assess your home's air quality over time.

This is an expensive air quality monitor, but many think it is worth the peace of mind. If you are going to monitor your home’s air quality, radon should be one of the things that you watch for since it is a known cause of lung cancer. This model takes 6 AA batteries, which are included and should last for around two years. Conveniently, the unit gives a low-battery alert when it is time to change them.

Best Budget

Airthings Wave Mini Indoor Air Quality Monitor

Airthings Wave Mini Indoor Air Quality Monitor


What We Like
  • Affordable

  • Small and compact

  • Comes with outdoor pollen monitoring app

  • App can run reports and collect data

What We Don't Like
  • Doesn't monitor all hazards

  • Batteries will need to be replaced

  • Smaller range

The Wave Mini is a cost-effective and compact device that monitors the levels of VOCs, humidity, and temperature. It sends alerts if hazardous materials reach high levels, allowing you to take necessary actions to prevent mold and other potential hazards in your home. Although it may not be as comprehensive as our top pick (the larger version made by Airthings), it serves as an excellent choice for those who want to start monitoring their home's air quality or add it to their existing system.

The Airthings app provides data based on your readings as well as pollen levels for your area. The actual air quality monitor does not measure pollen, however. It is affordable enough to put in every room—this may be necessary for large rooms and to get the most accurate readings for the whole home.

Best Compact

Aiment 3-in-1 Lightweight Portable Air Quality Monitor

Aiment 3-in-1 Lightweight Portable Air Quality Monitor


What We Like
  • Portable

  • Monitors carbon monoxide

  • Color-coded LED display

  • Audible alarm

What We Don't Like
  • Short battery life

  • Limited monitoring

  • Doesn't connect to smartphone

You can take this helpful air quality monitor on the go, so you will always have one when you need it. In fact, it clips onto a bag and can be turned on and off as necessary. It measures exposure to carbon monoxide as well as temperature and humidity. The display shows the current temperature, humidity level, and CO levels in parts per million (PPM). It categorizes via color so that you can quickly know whether you are approaching dangerous levels. Plus, it has an audible alarm to notify you if you are in danger.

Because it is designed to be portable and provide real-time feedback, you can run reports or connect the monitor to your smartphone. You will also need to recharge it frequently since the battery only lasts for around 30 hours of continuous use. This model is a good choice if you want to monitor the air in a specific situation, but not great for round-the-clock monitoring in your home.

Langkou 8-in-1 Air Quality Monitor

Langkou 8-in-1 Air Quality Monitor


What We Like
  • Large display

  • Stable base

  • Charging cable included

  • Backup battery

What We Don't Like
  • Does not have night display mode

  • Only monitors three things

The large LED display on the Langkou Air Quality Monitor shows the temperature, humidity levels, particulate matter, carbon dioxide levels, and battery life. The unit itself has a silver back and a black face with white LED letters and numbers, which make it easy to see, even at night. The base is wide, so you never need to worry about tipping it over. The display is 2.8 inches wide and covers almost the entire face of the unit.

To keep it charged, the unit comes with a USB cable and a 10-hour battery backup. It doesn’t monitor every airborne hazard but provides plenty of data in an easy-to-read display. Unfortunately, it does not have a night mode to dim the light when it is time to go to bed. You can respond to the audible alarm and turn the unit on and off using the push button on the front.

uHoo Smart Air Monitor

uHoo Smart Air Monitor


What We Like
  • Sleek design

  • Monitors many pollutants

  • App and reports are easy to use

  • Color-coded monitoring system

  • Won't run out of power

What We Don't Like
  • Best features require subscription

  • Needs access to a wall outlet

We’ll start by acknowledging that the uHoo Smart Air Monitor unit is expensive. It keeps track of a variety of potential hazards and other helpful information, including temperature, humidity levels, carbon dioxide, air pressure, total VOCs, particulate matter, and carbon monoxide. The only other thing that we wish it tracked is radon.

The smartphone app is one of the most helpful. It shows the levels as well as a color-coded system that categorizes them as good, fair, bad, or severe. That lets you get and understand the information with just a glance. The same reports and monitoring are available on your computer. The best features of the app are behind a uHoo premium subscription, although one year comes complementary. It does require access to an electrical outlet but won’t run out of power like battery-operated monitors.

What We Like
  • Comes with two rechargeable batteries

  • Can be charged using solar power

  • USB charging option

  • Long battery life

What We Don't Like

If you're looking for a reliable power source, the ECOWITT WH0290 is a top choice. This device can be powered through a rechargeable battery (two are included with your purchase), the USB cable that comes with it, or solar power (just charge the solar panel outdoors). You'll always know when it's time to recharge thanks to the battery life display, and the batteries can last up to two weeks with continuous use.

This air quality monitor is equipped to measure particulate matter, temperature, and humidity. While it doesn't measure mold, it will alert you if the air quality becomes unhealthy. The intuitive color-coded scale displays the Air Quality Index (AQI).

Best Smart Monitor

Awair Element Indoor Air Quality Monitor

Awair Element Indoor Air Quality Monitor


What We Like
  • Compatible with Alexa and Google Home

  • Helpful reports via app

  • Can get real-time measurements via smart home device

  • Works with smartphone

What We Don't Like
  • Display on unit is not easy to read

  • Not a lot of information provided on display

This Awair unit works with Alexa devices or Google Home devices and can provide you with real-time feedback—it tracks the top hazards and data points, including temperature, humidity level, carbon dioxide, VOCs, and particulate matter. It also provides an overall AQI.

Note that the actual display on the unit is very hard to see and read. To make much use of the data, you need to log into the app or use your smart home device to tell you what the readings are. Fortunately, there are plenty of helpful tools and reports that you can run to see how your data changes over time. You can even prioritize certain monitoring functions and look more closely at data at different times of the day.

Temtop M10 Real-Time Air Quality Monitor

Temtop M10 Real-Time Air Quality Monitor


What We Like
  • Simple, intuitive display

  • Provides overall AQI reading

  • Color-coded measurements

  • USB cable included

What We Don't Like
  • Short battery life

  • Does not monitor all hazards

The futuristic look of the Temtop air quality monitor makes it right at home among modern decor and home systems, while the superior monitoring technology keeps track of many potential hazards in your home’s environment. It measures temperature, humidity levels, VOCs, and particulate matter and displays the results with an overall AQI that is color-coded to safe, intermediate, and unsafe readings of green, yellow, and red.

You can also cycle through individual measurements, but that requires that you adjust the unit itself. It charges via an included USB cord and has a built-in lithium battery. The battery itself only lasts around six hours on a full charge, so it's best to keep it plugged in via USB unless you are actively monitoring a new environment. You will need to calibrate it when you change locations, however.

Final Verdict

Our top pick is the Airthings View Plus Radon & Air Quality Monitor. It has the most comprehensive monitoring and easy-to-read display, and it connects right to your smartphone and other monitoring devices as a hub. For a more affordable version, consider the Airthings Wave Mini Air Quality Monitor. It doesn’t measure as many things in the air but is perfect for smaller rooms and as part of a larger system.

What to Look for in an Air Quality Monitor


It's important to choose an air quality monitor that will provide you with a thorough, clear reading of your home's environment. Monitors that measure small particulate matter (ideally PM2.5) and VOCs will get you well on your way toward understanding the quality of the air in your home. Those two measurements are extremely important to maintaining healthy air conditions. Monitors that provide humidity, CO2, temperature, and air pressure measurements will inform you even further.


No air quality monitor will take up too much space, but if you want to test air quality on the go or in multiple locations, a handheld, battery-powered device that provides real-time readouts may be an excellent option. The Aiment Mini CO2 Detector is a portable device capable of detecting CO2 concentration, indoor and outdoor humidity monitoring, and temperature tracking.

Smart Capabilities

App-enabled and smart home-compatible air quality monitors are only getting more popular, but some high-quality options remain relatively low-tech. This Awair unit is compatible with Alexa and Google Home devices and can offer real-time feedback. The advantage of integrating your air quality monitor into the rest of your smart home setup is that it can interact with your thermostat or air purifiers to provide all-encompassing air quality control. Meanwhile, an app-enabled device will appeal if you're interested in additional information on your readings, recommendations to improve your home's air quality, and quality tracking over time.

  • Why is it important to monitor air quality?

    Indoor pollutants, like dust, dirt, smoke, and pollen, can be major sources of allergies and general discomfort. An air quality monitor can help you not only keep track of what kinds of pollutants are making their way into your home's air but even help you to learn how to reduce them in the future.

  • Can air quality monitors detect mold?

    Technically speaking, air quality monitors can detect particulate matter, of which mold is one type. Most mold is pretty easy to detect, though, so you probably don't need an air monitor to tell you when you have a problem. If you're concerned about the possibility of mold in your home, the best things to do are to tackle leaks immediately, keep indoor humidity low (many air quality monitors will tell you when it's too high), and increase ventilation.

  • What can you do to improve your home's air quality?

    Luckily, learning that your home's air quality isn't up to par is not a life sentence. Following a regular cleaning schedule, keeping your home well-ventilated, maintaining your heating and cooling systems, and purchasing air purifiers are just a few steps you can take toward improving your home's air quality.
