Indoor Air Pollution Information

Indoor Air Pollution

The Environmental Protection Agency (EPA) ranked Indoor Air Pollution among the top five environmental dangers. Often the air indoors is 2-5 times more polluted than the outside air; in some cases the contamination can be even worse than that. This has become an even greater problem in recent years with modern construction making buildings more air tight to retain hot or cold air as and conserve energy. This method of tighter building construction reduces air exchange with the outside, which results in trapped allergens, mold and other contaminants. This trapping that lead to the accumulation of these contaminants in the air and on surfaces, which can reduce indoor air quality (IAQ) and affect the health of property occupants. This air tight building construction can also lead to trapped moisture and elevated humidity, which is the primary cause of mold growth.

Indoor air pollution can come from mold, pet dander, dust mites and other sources

Indoor Allergens

There are other natural indoor contaminants that can reduce the indoor air quality and make the environment unhealthy for occupants with allergies, in addition to mold. The most common natural contaminants include:

  • Dust
  • Pollen
  • Dust Mites
  • Pet Dander
  • Insect Debris

Common natural factors that contribute to the spreading of these contaminants into and around your property can include:

  • Indoor Pets
  • Certain Household Plants
  • Certain Outside Plants and Trees Near to Your Home
  • Indoor Environmental Factors Such as Humidity, Temperature, Cleanliness and Air Filtration
  • Outside Environmental Factors Such as Humidity, Precipitation, Temperature and Windiness

Other Potential Contaminants

A variety of other contaminants can exist within your property. These contaminants often come from building materials, but can also make their way into your indoor environment through your tap water, from outside air or from contact with outdoor surfaces.

Common contaminants that can exist within a property other than mold or allergens can include:

  • Asbestos
  • Lead
  • Radon Gas
  • Carbon Monoxide
  • Volatile Organic Compounds (VOCs)
