How serious is the problem with the indoor air quality?
Strange as it may sound, indoor air quality is posing a serious threat to our health. In fact, the Environmental Protection Agency (EPA) have issued a warning proclaiming that indoor air quality is America’s biggest environmental problem. It is startling to know that indoor air is actually 2 to 10 times more polluted than outside air. A direct consequence has been the steady increase in the number of asthma and hay fever cases for the past few years.
