White fluffy stuff in attic.

Ideas on what this. It appears white or light gray like a coating of unsettled dust. First of all that white fluffy stuff was actually a blown in fiberglass insulation in my opinion.

The attic of my house is filled with a loose blow in insulation. However mold doesn t always grow in plain sight which is why it is important to get your home tested for mold as soon as you suspect a problem.
