I have the system and am very pleased with the way it performs. ....This unit is quite and most of the dust is captured in the cyclone jar.....I have used it for several months and have only changed the small bag in the vac-unit once, while dumping the jar many times...I also have a 20x20 box fan near the saw with air filter taped to it.....I also have the shop vac air cleaner near by that pulls the finer dust from the shop.....Just my two cents....works for me.
