What is Indoor Air Quality?

0

Indoor Air Quality (IAQ) refers to the effect, good or bad, of the contents of the air inside a structure, on its occupants. Usually, temperature (too hot or too cold), humidity (too dry or too damp), and air velocity (draftiness or motionlessness) are considered “comfort” rather than indoor air quality issues. Unless they are extreme, they may make someone unhappy, but they won’t make a person ill. Nevertheless, most IAQ professionals will take these factors into account in investigating air quality situations. Good IAQ is the quality of air which has no unwanted gases or particles in it at concentrations which will adversely affect someone. Poor IAQ occurs when gases or particles are present at an excessive concentration so as to affect the satisfaction or health of occupants. In the minor instances, poor IAQ may only be annoying to one person. At the extreme, it could be fatal to all of the occupants of a structure.

According to the Environmental Protection Agency (EPA), your exposure to air pollutants can be up to 100 times higher indoors than outdoors. The American Lung Association estimates that most people spend 90% of their time indoors, so clean indoor air is very important.

A. A study conducted by the U.S. Environmental Protection Agency found that indoor air could actually be more polluted than outdoor air. Considering that most individuals spend up to 90 percent of each day indoors–more than half of that time at home–you may be experiencing indoor air pollution without even knowing it. Today, homes are sealed more tightly to conserve energy. Unfortunately, this seals in mold, pollen, bacteria and other pollutants. And since the U.S. EPA ranks indoor air pollution among the top five environmental risks to public health, many homeowners are concerned. Fortunately, there’s a solution to most indoor air quality problems. KVN Heating & Air offers an array of choices designed to ventilate stale indoor air, zap airborne germs, trap airborne particles and moisturize parched air.
