The trouble with wood dust is that the most dangerous particles—the very fine ones—are the most difficult to collect. Under 10 microns in size, they hang longest in the air, penetrate deepest into the lungs, and are the hardest for the body to eject. Our corner of the woodworking world has been slow to tackle the problem of adequate dust collection, but more and more manufacturers are getting serious about the subject, and effective solutions are now available for every size shop. Learn the differences among the cyclone, the single-stage dust collector, and the shop vacuum, how to choose the right filter, and how to use a dust separator to make your system the best it can be.
