How good is the air you are breathing?

AS YOU RETURN TO YOUR OFFICE?

Article by: Dr. Ronald A. Wood PhD, BSc

Outdoor air supply is the only source of “fresh air” to replace the building’s “stale air”
and is generally contaminated with pollutants such as car and bus exhausts, industrial
pollutants and probably the exhaust from adjoining buildings.

Our lungs become the f nal f lter as air conditioning f ltration is designed primarily to
protect the system components, and generally does not f lter for gaseous air pollut-
ants.

Meeting the current rating requirements for indoor environmental quality doesn’t
automatically lead to clean breathable air, or wellness for building occupants. There is
a major dif erence between indoor environmental quality (IEQ), i.e. temperature and
humidity (comfort factors) and indoor air quality (IAQ), i.e. the air we breathe (essen-
tial to life).

We have little individual choice over the quality of the air that we breathe indoors, or
the total daily exposure.
