Indoor Pollutants in the Home

Diagram of a home indoor pollutants that air purifiers can clean

  1. Fiberglass Insulation: The jagged edged particles of fiberglass are of even greater concern than asbestos, which can still be found in older houses. Urethane is a further concern.
  2. Pressed wood in furniture and flooring: Manufactured with formaldehyde which is released as gas.
  3. Dry Cleaning: Source of toxic toluenes and PERC.
  4. Dust Mites: The excreta and body paints and plumbing pipes.
  5. Lead: Found in older paints and plumbing pipes.
  6. Aerosols in personal care products: A common source of organic gases, some of which are suspected carcinogens.
  7. Pesticides: Source of extremely toxic chemical that can be released into indoor air.
  8. Smoke from fireplace or wood stove: Open fireplaces can produce ash dust, carcinogenic tars and combustion by products like carbon monoxide and nitrogen oxides.
  9. Wall coverings: Plasticized wallpapers can emit VOCs; wood paneling is often manufactured with formaldehyde.
  10. Gas Stove: Can be a source of combustion by-products, such as CO and CO2.
  11. Household Cleaning Products: Can contain many harmful volatile chemicals, such as benzene and carbon tetrachloride.
  12. Draperies: Treated fabrics can contain formaldehyde.
  13. Tobacco Smoke: Tobacco Smoke contains 43 carcinogens, the danger to nonsmokers from second-hand smoke, especially in children, is now becoming recognized.
  14. Carpets: Source of formaldehyde. Harbor dust, dust mites and animal dander.
  15. Paints and Solvents: These are sources of many volatile chemicals, which are easily vaporized.
  16. Fuels: Storage of gasoline, kerosene, and other fuels can release volatile chemicals into household air.
  17. Pet Dander: Animal hair and skin flakes are a common source of allergens.
  18. Auto Exhaust: Such fumes can enter the home from the garage or nearby traffic flow. Carbon monoxide is the primary danger, and has a cumulative effect in the human system.
  19. Asbestos: Fibers reside in lung tissue and can cause lung cancer or emphysema.
  20. Radon: Radon gas is a natural emission where uranium exists underground. Radon carries radioactive particles that can be a dangerous cause of lung cancer.
