    The Rainbow Vac is not a HEPA vacuum. It will not do the job safely.
    The particles that you are concerned about are so small that they
    will not be thrown out of the air stream and will just flow with the
    air right on through past the water trap. What you need is a vacuum
    of the type used for asbestos removal they are very expensive and
    this is why wet mopping and wipe down is a more reasonable solution.
    Call the manufacturer and see if they will put in writing that their
    vacuum is certified for removal of asbestos or respirable crystalline
    silica, if not then do not trust that it is safe for this use.
