DID YOU KNOW...Bacteria, viruses, molds,
mildew, animal dander, cat saliva, dust
mites, cockroaches and pollen are listed
among the types of biological
contaminants that are often present in
homes or offices. Sources of these
pollutants are quite diverse. Viruses
are transmitted by people and animals,
pollens come from plants, pets have
saliva and dander, bacteria are spread
by people, animals, and soil/plant
material, protein from urine in mice and
rats is a potent allergen and can become
airborne when dry. When biological
contaminants enter the central/forced
air heating and cooling systems, these
systems become their breeding grounds.
Mold, mildew, and other pollutants are
then distributed throughout the home or
office. If standing water, water-damaged
materials, or wet surfaces are present,
they also become breeding grounds for
mold, mildew, bacteria, and insects.
Dust mites are a strong biological
allergen for many people and these breed
in damp, warm environments.
