Use and Care Manual

3. Indoor concentrations of some pollutants have increased in
recent decades due to such factors as energy-efficient building
construction (when it lacks sufficient mechanical ventilation to
ensure adequate air exchange) and increased use of synthetic
building materials, furnishings, personal care products, pesticides,
and household cleaners.
The EPA lists the sources of typical pollutants that people should be aware
of including substances of natural origin such as radon, pet dander, and
mold. In addition, the EPA also notes that “excessive moisture also
promotes the growth of common indoor pollutants like dust mites,
bacteria, and viruses which can impact health.”
Explaining how moisture and mold impacts health
The EPA explains that excess moisture in homes or buildings creates an
ideal environment for mold spores to grow. Being exposed to mold can
trigger allergic reactions and asthma symptoms in people who are allergic
to mold. With or without allergies, occupants may experience upper and
lower respiratory problems, as well as irritation of the eyes, skin, nose,
throat, and lungs when exposed to airborne mold particles.
The EPA lists a number of conditions that dampness and mold have been
linked to including:
• Worsening of asthma
• Coughing
• Wheezing
• Nasal congestion
• Sore throat
• Sneezing
• Rhinitis.
The EPA also mentions an uncommon disease known as hypersensitivity
pneumonitis has been associated with exposure to indoor mold in people
