Mold is a fungal growth that comes in different types and varies in color and appearance. It grows when there is an interaction between mold spores, humidity, and a moisture source. Mold usually appears on damp surfaces, cloth, and other porous materials. It is also known as mildew.

A few health effects and symptoms associated with mold exposure are allergic reactions such as nasal stuffiness, eye irritation, wheezing and/or skin irritation, asthma, and respiratory complaints.
