OVERVIEW
As buildings become more airtight and energy efficient, actively managing indoor air quality becomes more important. Not only are some air pollutants highly dangerous, but many—like radon and carbon monoxide—are undetectable by human senses. And with 90% of our time typically spent indoors, slight elevations of VOCs can amount to chronic exposures.
Here you’ll learn what pollutants to be wary of and ways to promote clean, fresh air, including:
-
finding the right level of ventilation
-
specifying products that won’t emit problematic chemicals
- controlling pressure differentials to avoid unintentional introduction of polluted air
