Air Ducts Facts

• Indoor air quality can be affected by contaminants found in your heating and air conditioning system.

• Proper cleaning of air ducts reduces allergy-aggravating pollutants such as mold and fungi, dust, pollen, pet dander and dust mites and improves operating efficiency.

• Many Americans spend up to 90 percent of their time indoors, often at home.  Therefore breathing clean indoor air can have an important impact on health.

• People who are inside a great deal may be at a greater risk of developing health problems, or having problems made worse by indoor air pollutants.  These people include infants, young children, the elderly and those with chronic illnesses.

• Biological pollutants are or were living organisms.  They promote poor indoor air quality and may be a major cause of days lost from work, school and of doctor and hospital visits.  Some can even damage surfaces inside and outside your house.  Biological pollutants can travel through the air and are often invisible.

• Some common biological pollutants are animal dander, dust mite and cockroach parts, infectious agents (bacteria or viruses) and pollen

• Except for the spread of infections indoors, allergic reactions may be the most common health problem with indoor air quality in homes.  They are often connected with animal dander and dust mites and pollen.
