causes poor IAQ?
Many things can contribute to poor indoor air, and you
might be surprised how common many of them are. Here
are some of the biggest offenders:
Poor ventilation is generally caused by dirt-clogged
or improperly designed HVAC systems.
Moisture Damage is one of the leading causes of fungal
contaminant within a structure. All moisture issues
should be addressed immediately to prevent IAQ hazards.
Mold, dustmites, and other microorganisms love humid
air and standing water.
Furnishings, carpeting, paneling particleboard, glue
and upholstery can emit formaldehyde or other volatile
organic compounds - (VOC's).
Dust, pollen, and automobile exhaust can be drawn in
through the ventilation system.
Charcoal grills and kerosene heaters emit carbon monoxide.
Wood and coal-burning stoves release nitrogen dioxide
and soot. Some gas-burning appliances emit both carbon
monoxide and nitrogen dioxide.
Office machines such as laser printers, copiers, and
some fax machines are a source of ammonia, VOC's, and
Cleansers, paints and pesticides release VOC's and other
contaminants. Some solvents, paint strippers, air fresheners,
and wood preservatives also release VOC's and other
