Aspergillus is a type of mold frequently found indoors. It can cause health problems.
Penicillium is often found growing on materials that have been damaged by water, including carpeting, wallpaper, insulation, and furnishings like mattresses. It’s one of the mold types that spread quickly and easily from one part of the home to another.
