Reading up on the stuff that's actually coming out of the can, it doesn't look like there are particles that are small enough to actually aerosolize into the air. They tout wool and mohair as candidate things that can be sprayed.

I have my doubts whether breathing the small fibrous particles that are contained in the spray won't have some unhealthy consequences.
