Though often used interchangeably, the EPA describes that mold and mildew are not quite the same things. Mold and mildew - and the chemicals produced by them - are not great for your personal health or the air quality in your home. Though more research is needed, some common symptoms of exposure to microbial volatile organic compounds may include: There are hundreds of different MVOCs formed by mold and mildew and many of them may pose health risks. They have a very low odor threshold, which means you may smell them easily and, when you do, the odor is strong. While volatile organic compounds (VOCs) are categorized as man-made or industrial chemicals, MVOCs are naturally occurring. So that musty odor you are smelling is not “just” mold but is a result of the chemical compounds released at different stages of the mold’s growth. As mold forms, grows, and spreads, it emits gasses known as microbial volatile organic compounds (MVOCs). When all of the other environmental elements combine with condensation, moisture from humidity, or leaking water, mold begins to grow.

The last ingredient - moisture - is the biggest problem.
