This device lets you test the air pollution in your house
The air inside our homes might not be as fresh as we think. Tiny, invisible pollutants from wood smoke, household cleaners, building materials and other everyday items can put people at risk for asthma, heart disease and more.
For people who can’t afford expensive indoor air quality monitors, detecting these particles is next to impossible. But researchers at Carnegie Mellon University have developed a new in-home sensor, called Speck, and plan to make it available to people virtually for free.
