- Indoor air pollution at home
or work -- the endless dusting, vacuuming and sanitizing doesn't
seem to help, because air form a contaminated air duct system
is continually being recirculated.
|
- The ideal breeding ground for
bacteria, molds, fungi, spores, mites, and many other harmful
allergens is caused by the dusty, dark, damp climate of the cooling
and heating system.
|
- The unhealthy mixture of contaminated
air getting a free ride to every room or office each time the
air blower is activated.
|
- Inefficient and unsafe operation
of both the heating and cooling equipment due to a build-up of
dust and dirt.
