My intent was not to get in a huge discussion over dust but only to present a different viewpoint. Not everyone has the space or money for a 1/2 micron dust collection system. But, people should be aware. Even a 5 micron dust particle can stay in the air for 30 minutes. Is it worth time discussing the hazards of dust….I think so.
Most people on forums are aware of the hazards of dust and do what they can. IMHO a dust collector with a 30 micron bag is a hazard pumping out way too much fine dust.
