2. Indoor air quality – industrial hygeine
model
1. Avoid generating
contaminants indoors when
possible.
2. Remove known
contaminants where and
when they happen.
3. Dilute unknown and
unavoidable contaminants. common sense,
not rocket science.

3. Avoid indoor contaminants
 No smoking policies
 Formaldehyde-free
building products
 Low/no VOC products
 Mold remediation
 Asbestos
 Eliminate indoor
combustion appliances

4. Remove known contaminants where and
when they happen.
 Bath and kitchen
exhaust
 Moisture
 cooking byproducts
 Radon mitigation
systems
 Direct-vented
combustion
appliances

5. Dilute unknown and unavoidable
contaminants
 Natural infiltration
 uses a lot of energy
 air can come through attic,
crawlspace, garage – is this
clean?
 pests use the same pathways
 Tight home + mechanical
ventilation
 efficient
 reliable – does not depend on
weather
 can add filter or dehumidifier
to system
