Have a hanging jet air filtration system and use 2 different vacs that I hook up to band and table saw. I also have a cheap harbor freight 1hp air unit hooked to my sander and grinder. Still have a lot of dust. My one craftsman vac's filter is about shot and the start switch on the other just died so I by passed it to use it. I am starting to think what is a better solution. I always find my vacs are clogged and the filters need cleaning or I lose suction. What about the dust deputy's are they any good? How does any one else solve this problem what out spending a fortune and using up a lot of space?
