Mildew
A type of mold that appears as a thin, often white or grayish coating on damp surfaces. Mildew typically grows in areas with poor ventilation and high humidity, such as bathrooms, windowsills, and basements. While often less invasive than other molds, it can still cause odors, surface damage, and contribute to indoor air quality issues.
