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 9^th 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

Via airthings.com

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.
