So, slightly hijacking the discussion . . .
Given my shop is in an attached garage, and I have no way to vent outside without opening the garage door, which would be pointless and makes the filter/vent debate irrelevant . . .
I am collecting from a 3hp cabinet saw, router table, 8" jointer, 14" band saw, portable planer, portable oscillating spindle/belt sander, all of which are mobile. I do not have a 220 option for DC.
So, is the BEST DC (not cheapest, but the best) the Harbor Freight 2HP with a Thein Baffle and Wynn Cartridge Filter or the Oneida Mini-Gorilla - HEPA?
