When you find mold growing in your home, there’s no two ways about it – it’s gross. But how dangerous is it, really?

The truth is that mold spores exist everywhere in nature and we are all constantly breathing them in.

However, when the level of mold indoors exceeds the level of mold outdoors, that can trigger allergic symptoms in sensitive people. And the dreaded toxic or “black” mold can do some serious damage.

The category of Cladosporium includes about 40 different species. It’s quite common and can be found in colors including green, gray, brown, or black.

Typical locations are wallpapers, painted walls, carpets, wood furnishings, and any organic surface that is often damp.

Most Cladosporium mold does not produce mycotoxins, but has been linked to pulmonary edema and emphysema in certain people.
