Why Worry About Indoor Air Quality?

The Environmental Protection Agency ranks poor indoor air quality among the top five environmental risks to public health. Levels of pollution inside can be 2 to 4 times higher (as much as 100 times higher) than outside air, and people can spend up to 90 percent of their time inside

Poor air quality can affect the health of your family. Many factors can affect air quality, and eliminating the source of pollution, increasing ventilation, and maintaining air conditioning systems regularly are the most effective methods of improving indoor air quality.

Types of Pollutants

Allergens such as pet hair or dander
Toxins such as lead, pesticides, ionizing radiation
Irritants such as formaldehyde
Asphyxiants such as carbon monoxide
Pathogens such as viruses, bacteria, mold
Carcinogens such as asbestos and cigarette smoke
Mutagens such as PAHs (byproducts of fuel burning) and radon

Forms that Pollutants Can Take

Particulates
Vapors
Fumes
Gases
Biological

Common Sources of Indoor Air Quality Problems

Water (through evaporation and aerosolization)
Animals/pet dander
Bedding – after two years, 1/3 of the weight of a pillow is from contaminants (including dust mites) and dead skin cells. Consider purchasing good-quality pillow, mattress and box spring encasings.
Furniture and carpeting
Poorly maintained air conditioning system and/or dirty ducts. Change or clean the A/C filter regularly and have your ducts cleaned
Combustion appliances
Local outside environment
Chemical storage – do not store chemicals near or and an air conditioning vent as that can distribute pollutants in the air you breathe
Personal hygiene products such as hair spray, air fresheners, spray-on sunscreen
Second-hand tobacco smoke
Insects

Key Questions

If you feel that you may have an indoor air quality problem, here are some questions to ask:
When did the problem start?
What things changed during that time?
What is the core problem?
Are there any other possible causes?

Radon

Radon testing kits can be acquired at: Home Depot, Lowes or other large hardware retailers.

Ozone Generators

The American Lung Association does not recommend the use of devices that intentionally create ozone for the purpose of air cleaning or odor removal. Ozone is a powerful lung irritant. Ozone can reduce lung function. Low levels of ozone are not effective in removing most common household pollutants.
