Indoor Air Quality (IAQ) affects the health and comfort within a structure such as your home. The air within a home or building can be more polluted than the air outdoors. Research indicates that people spend approximately 90 percent of their time indoors. Therefore, the risks to health may be greater due to exposure to air pollution indoors than outdoors.
When it comes to individual comfort, there is no standard for indoor air quality. It is based on an individual’s tolerance to pollutants. Some have no sensitivity to chemicals while others are very vulnerable.
