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

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

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

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

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

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

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

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

Questionable Control Methods Ozone generators Ion generators HEPA filters Duct cleaning
