We have all heard a great deal about the air quality in our outdoor environment and how pollution, manufacturing, transportation, our carbon footprint, etc. is taking a toll on the air we breathe. But the air quality on the inside of the home —what the U.S. Environmental Protection Agency calls Indoor Air Quality (IAQ)—is something to keep a watch on as well.

People who live in urban environments spend up to 90 percent of their time indoors, according to a 2016 study published in the Science of The Total Environment journal. Researchers also noted that indoor air is a major factor in determining life expectancy, with "...household air pollution is ranked the 9th largest Global Burden of Disease risk."

That's why investing in a smart air quality device is a smart move to protect your family. These devices below can help you keep watch over the levels of radon, air particles and CO2 levels to hopefully help you live in a more breathable home and in a healthier indoor environment.

Wave: Smart Radon Detector


Wave makes it easy to detect levels of radon in your home with or without a smartphone. With a wave of your hand, the device, even in the dark, indicates whether you have normal or dangerously high levels of the radioactive gas by changing colors. Green is good, yellow is a warning, and red is a problem. Radon gas can leak into homes through cracks in walls and floors, as well as well water and can be found in any home in the United States, according to the U.S. Environmental Protection Agency. It's worth monitoring. Wave's mobile app works with iOS or Android devices, and displays in both metric and imperial units with Bluetooth connectivity. Wave is priced at $199, and is easy to attach to nearly any wall or ceiling and has a 1.5-year battery life.

Xiaomi Mi MiHome Smart Particulate Monitor


This tiny air quality monitor is only 100g but it does a big job in distinguishing particulates in the home. Xiaomi Mi MiHome uses an indicator light to quickly alert users of the air quality in the home with an OLED display. The company also produces the Xiaomi air purifier, which can be paired with the monitor and start cleaning the air in your home. The 4100 Mi Air Purifier uses two high-performance fans to take in and expel air upwards through four ducts. Clean air is sent towards the ceiling, circulating in all directions before it is sucked back into the purifier. Connected to a smartphone, check on the current air quality in your home as well as historical data. The app will recommend when to close windows or open them depending on outside air quality.



Awair keeps track of chemicals and toxins in your home, and also provides personal recommendations for you to make adjustments to clear the air in your space. With a quick glance, you can see the air temperature, humidity levels, CO2 levels, chemical components, and dust in your surroundings with an Awair color-coded score to sum it all up. The $199 Awair pairs simply with Alexa and Nest, allowing you to keep your connected home running with even more hi-tech capabilities. The device uses Wi-Fi and Bluetooth to connect.
