  1. Residential Indoor Air Quality by John Martyny, Ph.D., CIH National Jewish Medical and Research Center

  2. Factors Effecting Residential IAQ • Heating and Ventilating System • Energy Sources • Construction Type • Residence Location • Occupant Activities

  3. Heating and Ventilating System • Type of System • Radiant Heat vrs Forced Air • Hot Water • Condition of System • Filter Change • Vent Condition – CO and CO2 • Air Conditioning • Moisture • Humidity

  4. Energy Sources • Fossil Fuel Combustion • Carbon Monoxide • Oxides of Nitrogen • Vented vs. Un-vented • Electrical • Typically lower emission rates • Space Heating • Vented vs. un-vented

  5. Construction Type • Crawlspaces • Moisture and Mold Concerns • Ventilation Concerns • Emissions • Furniture • Carpeting • Insulation • Water Infiltration • Tightness • Attached Garage

  6. Residence Location • Setting • Rural vs. Urban • Distance to Traffic • CO • Diesel Particulate • Climate • Humidity • Air Conditioning

  7. Occupant Activities • Smoking Habits • Hobbies • Wood Working • Pottery • Sculpture • Pets • Pesticide Usage

  8. Control Measures • Use of HEPA vacuum cleaners • Whole house vacuum system • Furnace filter upgrades • Reduction of fleecy materials • Low emission products • Damp cleaning • No smoking inside • Hobby dust and emission control • Moisture control

  9. Questionable Control Methods • Ozone generators • Ion generators • HEPA filters • Duct cleaning
