I am looking at getting a air cleaner for the shop as I am getting tired of the dust everywhere and in my clock shop. Dust collector does pretty good but not quite good enough when sanding. I have seen the one from PSI and like the features. Body shop here uses 3 of them. My question is if I get this air cleaner, hang it in the shope and use it along with the DC would I need the Trend face shield or would a dust mask with the dust filters be ok? It is getting the fallish time of year and winter won't be far behind which means the doors won't be open and box fans blowing the dust out. Any help would be appreciated.
