David, as you most probably know I introduced Clearvue to Oz and I very rarely sold any filters at all. The separation is so good no dust can be seen in the exhaust and no dust settling is evident at the exhaust even over a long period of time. I get why users in cold climates need to use filters and that requires very good separation if a cyclone is used and at a larger production scale "hobbyist"?cyclones have limitations that makes them unsuitable for production shops. Having said that timber yards in Oz used to have huge cyclones that made huge noise but those days are gone.?
David, I can understand your friends needing filters if they are not using a cyclone.
