Today, an average person spends most of his or her time indoors. According to the Environmental Protection Agency (EPA), concentration of air pollutants indoors can be up to 70 times higher than in the surrounding outdoors. As such, indoor air quality is closely related to health.

The number of people affected by various respiratory illnesses is on the rise, and nearly 28% of all people suffer from allergies.


Studies show that for 1 in 6 cases, allergy symptoms can be significantly alleviated simply by improving quality of the air that people breathe. Considering the profound effects that air quality has on human immune systems, as many as half of all illnesses are either aggravated or directly caused by indoor air pollution.

Here are some facts about the relationship between indoor air quality and health.

  • Most people spend 60% to 90% of their time indoors. (Canadian Lung Association)
  • The levels of some hazardous pollutants in indoor air has been found to be up to 70 times greater than in outdoor air. (USEPA)
  • More than 50 million Americans suffer from allergies.
  • 10-12 million Canadians suffer from Asthma. (Canadian College of Allergists)
  • One out of six people who suffer from allergies and asthma do so because of the direct relationship to fungi and bacteria in air duct systems. (Total Health and Better Health Magazines)
  • Contaminated air can cause headaches, nasal congestion, or other sinus problems, especially during the night and in the morning.
  • Children and the elderly are especially affected by polluted indoor air. (Department of Consumer Affairs)
  • Most commercially available fiberglass furnace filters are less than 7% efficient. (ASHRAE)
  • Studies have shown that two out of three indoor air quality problems involve the HVAC/Air Duct System.
  • The major source of various persistent “musty” or “stale” odors are contaminated air ducts, furnaces or air conditioners.
  • “Constantly dirty house syndrome”, a condition when all furniture in the house gets quickly covered by dust shortly after air duct cleaning, is directly caused by dirty air ducts.
  • Dirty air ducts are major sources of dust, dirt, pollen, animal dander and other airborne contaminants. They are also an ideal breeding ground for mold spores, bacteria, fungus, mildew and other microbes.
  • Regular removal of contaminants from the entire HVAC/Air Duct system is widely recognized and recommended by industry experts as the most effective way to eliminate air duct pollutants.

The method used by Comfort Clean insures that your ducts are being cleaned with the most advanced contamination source removal equipment available. This high tech, state-of-the-art system is widely recognized as the most significant break-through in duct cleaning equipment technology in the past 30 years.
