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.
