Indoor air quality is often overlooked by most families. The focus is always more on the heating and cooling systems and if a home is comfortably warm or cool. Not many people actually look at whether or not the indoor air quality is healthy and desirable.
IAQ is an acronym used to denote indoor air quality. In an ideal or natural scenario,indoor air quality would have been the same as the outdoor air quality but since homes are built in a manner that aims at keeping the hot air out during summers and cold air out during winters, there is a different environment created inside a home. The lack of
ventilation is one of the primary reasons why indoor air quality gets degraded. Most heating and cooling systems have ventilation systems but that still restricts natural cross ventilation, thus regulating the indoor air quality.
As per the Environmental protection Agency, IAQ has become a top priority that every family should take seriously. The EPA has founded that most homes today suffer from what has been referred to as the ‘Tight Home Syndrome’. These findings have been supported by the American Lung Association and the Consumer Product Safety Commission has been harping on organizations and heating/cooling system manufacturers to take note of indoor air quality while making their products.
With an enclosed home, the dirt, sick and stale air that is trapped inside due to lack of natural airflow and cross ventilation, creates indoor air pollution. This is not a very healthy air to breathe in. The indoor air quality suffers from rising levels of particles,germs and gases. The Center for Disease Control has published in several reports that tighter homes that are aimed at conserving energy have a risk of creating an indoor environment that becomes a thriving ground for bacteria, mold, gases including the hazardous carbon monoxide, radon and others, dust, allergens, pollen and many other particles, germs or gases. The indoor air quality can be as much as five times or even hundred times more polluted than outdoor air.
The outdoor air gets polluted but due to natural cycles of ionization, changes in weather, sunlight and UV rays from the sun, the contaminants or pollutants are cleansed from the air, which is not possible with indoor air. As most people spend more than 90% of their time indoors, the indoor air quality has to be checked and should be a top priority for all and sundry.
