An indoor air quality monitor can help you diagnose indoor air quality issues and take action by cleaning air ducts or replacing your HVAC system.

We researched dozens of indoor air quality monitors, evaluating their effectiveness, accuracy, ease of use, and smart home compatibility. Our best overall pick is the Airthings Wave Plus, which detects radon and offers easy readability and impressive battery life.

Here are the best indoor air quality monitors.

Final Verdict

The Airthings Wave Plus Radon & Air Quality Monitor (view at Amazon) goes above and beyond by monitoring not only CO2, TVOCs, temperature, humidity, and air pressure, but radon as well. For a more budget-friendly option, we recommend the Airthings Wave Mini (view at Amazon), a battery-operated model that checks TVOCs, mold risk, humidity, and temperature.


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 location, a handheld, battery-powered device that provides real-time readouts is an excellent option. However, it may come at the cost of a detailed display or sophisticated design. On the other hand, a device designed to stay in one place, say, on the wall or a tabletop, may be a little more aesthetically pleasing, if a little larger.

Smart capabilities

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


  • Indoor pollutants like dust, dirt, smoke, and pollen can be a major source 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 learn how to reduce them in the future.

  • 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 thing to do is tackle leaks immediately, keep indoor humidity low (many air quality monitors will tell you when it’s too high), and increase ventilation.

  • 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.
