Poor air quality is usually obvious. It’s the parade of cars idling during your school pick-up, or a nearby factory belching smoke. But experts say the quality of our indoor air—what we breathe while cooking, watching TV, and sleeping—is just as important as outdoor air.
“When pollutants get emitted outside, there’s a giant volume into which they’re mixing,” says Brett Singer, a scientist at Lawrence Berkeley National Laboratory. “Your house is a relatively small volume. Whatever pollutants get emitted inside, there’s a limited amount that they’re going to get diluted and it takes a while for them to clear out.”
