What Does Indoor Air Quality Really Mean?

A healthy indoor environment is one in which the surroundings contribute to productivity, comfort and a sense of health and well being. The qualities of good indoor air include:
  • Introduction and distribution of adequate ventilation air
  • Control of airborne contaminants
  • Maintenance of acceptable temperature and relative humidity
  • Reduce energy costs
Poor indoor air quality can cause problems and have serious consequences such as:
  • Increasing health problems such as cough, eye irritation, headache and allergic reactions
  • Reduced productivity due to discomfort and stress and increased absenteeism
  • Accelerated deterioration of furnishings and equipment
  • Strained relations between employees and employers or household inhabitants
  • Increases energy costs
  • Makes home more susceptible to house fires

Is Air Quality Important? - Yes!

For many years health authorities and government agencies have raised our awareness to the dangers of outdoor air pollution and have concentrated their effors of finding ways to reduce pollutants generated by automobiles, factories, constructions and mining.
Over the past 2 decades, scientists have been carefully examining the indoor air environment of our offices, factories and homes and they have found this environment in many cases to be even more hazardous to our health than outdoor air.

Indoor air contaminants can originate within the building or be drawn in from outdoors. Particulate matter can come from far away places like blowing desert sands and volcanic eruptions or from nearby sources such as pollinating trees, industrial emissions, vehicle exhaust, cleaning chemicals and pesticides. If these contaminant sources are not controlled, problems can arise. Statistics show that 1 out of 5 Americans suffer from allergies caused by substances found in the home and office. Deaths related to asthma have risen 40%.
