Moving that much air HAS to have a noise factor, IMO. As for clearing out the existing dust: Open all the doors & windows. Put a good mask on and have at it with the air compressor - every shelf - every nook and cranny. Mine gets that every 10 years or so.<G></DIV> <DIV>High ceilings help to keep the dust out of your face, BTW.</DIV> <DIV>Best Regards,</DIV> <DIV> </DIV> <DIV> </DIV> <DIV>Joe Garrett, R.P.T.
