Inside Air Quality Facts
Did you know that the air quality inside your home is probably not as good as you think
it is. Even if you are an excellent house keeper, your air quality may be worse inside
your home than the air outside. Here are just a few facts about the air quality inside most
buildings.
• Air pollution contributes to lung disease, including respiratory tract infections, asthma
and lung cancer. Lung disease claims close to 335,000 lives in America every year and
is the third leading cause of death in the United States. Over the past decade, the death
rate for lung disease has risen faster than for almost any other major disease. - American
Lung Association
• Indoor air quality is two to five times - and occasionally 100 times worse than outdoor
air! And it is estimated most people spend 90% of their time indoors! - U.S.
Environmental Protection Agency
• 87% of American homeowners are not aware that pollution may be worse inside their
homes than outdoors. - American Lung Association
• Six out of 10 homes and buildings are "sick" and are hazardous to occupants.
- U.S.Environmental Protection Agency
• Allergy and asthma are increasing at epidemic proportions - affecting one out of five
Americans. - American Journal of Respiratory and Critical Care Medicine
• More than 15 million Americans are estimated to have asthma, including one in 13
school-age children. - U.S. Environmental Protection Agency
• About 500,000 hospital admissions and 5,000 deaths are attributed to asthma annually.
-Online Allergy Center
• An estimated 100 million days are lost to asthma each year and asthma causes 10
million days of school absences annually. Direct and indirect expenses related to asthma
are estimated at more than $6 billion a year. - Online Allergy Center
• Dust, dander, mold, mites, pollen and other allergens make millions of allergy and
asthma sufferers miserable in their own homes. Homes with pets require extra-
thorough, deep cleaning.
So why has the air quality become so bad inside of most building?
• Homes built after 1979 have tighter insulation wraps - trapping smoke, odors and other
contaminants indoors.
Due to the rising cost of energy in America there was a change in how buildings and
homes were constructed. The use of tyvec (c) and other wrapping products were
designed to keep air inside buildings resulting in lower heating and cooling costs.
However this resulted in these buildings no longer being allowed to "breathe". Previously
air was not trapped inside the home. Buildings were drafty, and the "bad" air inside
escaped and was replaced with cleaner outside air. In a sense we traded cleaner air for
lower energy consumption.
Today even normal everyday tasks such as cooking and burning candles has a drastic
affect on the air quality inside the home. Cooking greases and gases released into the air,
along with wax and smoke from candles are trapped inside the home. Not to mention
other things such as dust, dirt, and dander. These are now normal everyday contaminants
in your home. So What can be done? How can we improve the air quality inside our
homes without sacrificing our energy efficiency?
