SIDE EFFECTS ARE

INDOOR AIR CONCERNS

Most people spend at least half of their

Poor indoor air quality can cause

respiratory problems.

Poor indoor air quality can be more

harmful for children .

insufficient fresh outdoor air entering a ventilation

system are often the direct result of overzealous

energy-saving procedures.
