What makes indoor air so much worse than outdoor air? Our indoor
spaces are becoming more and more polluted as they are more tightly sealed,
making them efficient for heating and cooling but inefficient for maintaining
clean air. Thus the indoor air is not circulated or exchanged with outside air
to dilute the pollutants produced naturally and by the materials used to
manufacture our buildings.
Outdoor air pollution gets diluted because of the huge expanse of air thus
making the pollution
indoors 2 to 5 times, and in some cases 100 times, more polluted than the
outside air. This
is an important fact to consider since we spend the vast majority of our time
indoors, whether
it is in the home or in the office.
Cleaning the air with air cleaners should be a continuous process. Our skin
sheds, people
cough and sneeze, dust circulates from other rooms, and other pollutants
constantly enter
the air space. Pollutants, living and dead are continuously being added to our
breathing spaces.
Left unchecked, their concentrations build up and can effect our health and
well being. The
National Resources Defense Council (NRDC) estimates that approximately 64,000
premature deaths
from air particles take place each year, more deaths than from AIDS and breast
cancer combined.
Many people have conditions and sensitivities, which are exacerbated by the
contaminants
in ordinary air. Too often, we shrug it off as "allergies" and assume we are
destined to a
life of drugs, chronic fatigue, and discomfort. The relationship between air
contaminants
and the suffering from these conditions, while obvious, is mistreated. We tend
to focus on
the symptoms rather than remove the source of irritation: the
contaminants. |
