I dunno. One of those "wait and see" things.

Junk normally shouldn't get in there because the blower is downstream of the cabin filter. It's not a perfect world, though.
The motor brushes are molded out of a fine powder similarly to the way pencil lead is made. Ever encounter a chunk of "something" in a pencil lead that isn't exactly pencil lead? The same thing can happen with motor brushes. When that happens the brush can get a little noisy until the snag breaks free.
