Indoor air quality refers to the air quality within your home or business. You may assume that what’s inside your four walls is fine (why wouldn’t it be?), but the truth will surprise you.
The World Health Organization (WHO) estimates that 7 million people in the world die each year as a result of air pollution exposure. Being indoors doesn’t make a difference, as indoor air can be 10 times more polluted than outdoor air. Furthermore, new data reveals that indoor air quality may be linked to cardiovascular disease, stroke, and some cancers.
