Indoor*Air*Quality could be one of the most important health concerns facing your family today.
A lot has been written lately about "Indoor Air Quality". In fact, the Environmental Protection Agency (EPA) recognizes it as one of today’s most significant environmental health threats. Because every time you spray a vaporous chemical... every time someone exhales cigarette smoke... every time a guest walks in with the flu... particles and germs are released into the air. And they stay there along with outgassing from new carpets and furniture, odors from your pets and other contaminants from countless sources in your home.
Today’s homes are so tightly sealed and well insulated that airborne pollutants cannot escape to the outside. So you and your family breathe them in, over and over again.
According to Popular Science Magazine, "a typical house contains thousands of odorless, colorless chemicals" - enough, says the EPA, "to match the thick smog around Los Angeles on a hot summer day."
The condition is so serious that it has led to government regulation in public places. The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) has adopted a Standard to ensure quality air in business, industrial and public buildings. The Standard (62-89) specifies bringing in outside air to replace indoor air at the rate of 1/3 air change per hour or at least 15 cubic feet per minute for every occupant, whichever is greater. The Standard has been adopted by many regulatory agencies and state building codes.
