I, too, am still using my Ridgid shop-vac for DC, and a fan pointed out
the window as an additional vent. I do have an ultra-fine filter for
the shop vac, which helps. The shopvac works well when attached
directly to my router table/bandsaw/RO sander, and I haven't had any
problems with dust flying around or building up anywhere else in the
basem... shop, as long as I have the shopvac attached directly to the
tool.
Interesting to read about them compared side-by-side, though!
