Spores and microscopic fragments of mold growth are a natural component of both outdoor and indoor air. However, when molds germinate and grow, they can produce large amounts of spores. Recently, concern has arisen that elevated levels of mold spores in indoor living or working environments may increase the risk of adverse health effects, particularly respiratory problems.

Molds produce tiny spores to reproduce. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet and foods. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed.

Areas that have high mold exposures include bathrooms, kitchens, window areas, flooring and carpets. Potential health effects and symptoms associated with mold exposures include, but are not limited to, allergic reactions, asthma and other respiratory complaints.
