Before buying my second Oneida Dust Deputy I considered the Dustopper for space reasons but then I saw this useful DIY test/review:
The conclusions seem similar to what others are saying here.
Also, I fit my first Oneida Dust Deputy under a standard workbench by creating a recessed lid for the 5 gallon bucket from wood. This cut down on the bucket capacity a little but the extra couple of inches gave me enough space under the bench to connect the hose to the top of the Dust Deputy. I’m not making that change to my new one as I’m opting for a separate enclosure eventually. I used to use a Ridgid vac with “HEPA” filters/bag and the exhaust vented outside but I am now switching to the Festool CT15 with true HEPA filtration (as I understand, better seals around the filter to prevent air from bypassing the filter) and I will still try to vent it outside.
